For most graduate students, the dissertation is the longest and most time-consuming paper they write throughout their education. This project aims to address a research question in the student’s field and build on existing bodies of scholarship.

Additionally, the dissertation showcases the student’s mastery of research methodologies. Because a dissertation must accomplish several goals, they tend to be ambitious and lengthy.

Most dissertations are 100 to 250 pages long. But many factors impact the length of a dissertation, including:

  • Academic field . Each discipline has different norms regarding dissertation content and length. For instance, literature dissertations often include extended close readings of texts, while science dissertations focus more on data analysis and research design. As a result, humanities dissertations are typically longer.
  • Institutional requirements . Most colleges and universities specify a minimum number of pages for the dissertation. You can ask your academic advisor or the graduate studies office about specific dissertation guidelines.
  • Topic complexity . Broad or complex research questions may require more data and analysis to answer, resulting in a longer dissertation.
  • Individual writing style . Some doctoral students enjoy writing elaborate and detailed sentences, while others prefer to get straight to the point.
  • Research methodologies . The approaches and methods used in the research can dramatically affect the length of the dissertation. For example, some dissertations include case studies, which may require lengthy explanations and analyses. Others use quantitative research methods and may include a number of charts and figures.
  • Committee feedback . Graduate students typically write their dissertations under the supervision of a faculty committee. These professors may recommend adding or cutting material during revision, impacting the dissertation’s final length.
  • Future goals . Some doctoral students plan to revise their dissertation and publish it as an academic monograph after graduation. Writing a longer dissertation gives them more material to adapt for their book.

Reading dissertations from your department and field can give you a better sense of the typical length.

How Long Are Dissertations by Discipline?

The answer to “how long is a doctoral dissertation?” varies by field. In some disciplines, it’s common for graduate students to spend several years writing extensive manuscripts. Other fields produce shorter dissertations of approximately 100 pages.

Here are a few examples of dissertation norms for different disciplines:

  • Arts : Students studying art and creative writing may produce a creative dissertation. These projects typically consist of a theoretical introduction and a creative project, such as a poetry collection or a series of paintings. Creative dissertations may have fewer than 100 written pages, but the artistic elements can still be time-consuming.
  • Chemistry : These dissertations typically range from 100 to 150 pages. They typically describe experimental methodologies and draw conclusions from the author’s findings.
  • Computer science : Dissertations in this field are generally 50 to 150 pages long and often include quantitative data and algorithms.
  • English : PhD students in this field frequently write lengthy literature reviews and provide in-depth analyses of novels and other texts. English dissertations may range from 200 to 350 pages.

Faculty in your discipline can help you understand dissertation expectations.

Average Dissertation Length Per Chapter

Dissertations typically have similar components and structures across disciplines. Here are six common chapters and their average lengths:

  • Introduction : The first chapter introduces the primary research topic and explains its relevance to the field. The introduction also provides a brief overview of the investigation method. Most introductions are 10 to 25 pages long.
  • Literature review : This chapter situates the project within the broader discipline. The author analyzes existing sources already written on their research topic and identifies biases or gaps that their own project remedies. Humanities dissertations tend to have 20 to 30 page literature reviews, while STEM dissertations devote 10 to 20 pages to this component.
  • Methodology : The third chapter typically focuses on the methods and techniques used to gather data. Ideally, this description should contain all the details that another researcher would need to duplicate the experiment and verify the results. The methodology chapter ranges from 15 to 25 pages, depending on the complexity of the research.
  • Findings : This section analyzes the collected data and discusses the results of the research project. It often includes charts, diagrams, and other data visualizations illustrating the findings. This chapter could be 20 to 50 pages, depending on the number of images and the amount of text needed to thoroughly examine the results.
  • Discussion : This chapter explains the significance of the results. The author may also compare their findings to previously published scholarship. The discussion is typically 15 to 25 pages.
  • Conclusion : The author summarizes their findings, acknowledges the limitations of their research, and suggests avenues for future studies. Most conclusions consist of 15 to 20 pages.

Some dissertations deviate from this format. For instance, English dissertations may devote several chapters to critical analyses of different genres or authors.

What Is a Dissertation?

A dissertation is a lengthy written document that a doctoral student produces based on their original research. This project demonstrates the student’s expertise in their area of specialty and contributes to existing knowledge in the field.

Dissertations typically fall into one of two categories. Empirical dissertations require students to collect and analyze data. For instance, a psychology student may interview people about their mental health, while a marketing student could interpret sales data.

Theoretical dissertations focus on analyzing existing scholarship and secondary sources. For example, a literature student might research psychoanalysis and apply this approach to superhero comics.

How Many Pages Is a Dissertation?

The length of a dissertation varies by discipline, institution, and research project. Some dissertations can be as short as 50 pages, while others may total 400 pages. But the average dissertation ranges from 100 pages to 250 pages.

Dissertations in the humanities and social sciences are typically the most extensive. These projects often include detailed analyses, case studies, and literature reviews. By contrast, dissertations in STEM fields like economics and mathematics are often 150 pages or less.

Students in these disciplines frequently use mathematical formulas and data visualizations to prove their findings, resulting in less text.

Why Are Dissertations So Long?

Dissertations are typically the most extended assignments that students complete in graduate school. Several factors contribute to their length, including:

  • Depth of research . Doctoral students can spend several years researching their topic and analyzing data. This extensive work often takes hundreds of pages to summarize and explain.
  • Literature review . Most fields have extensive bodies of scholarship, so students spend many pages analyzing sources and contextualizing their projects.
  • Bibliography . Dissertations often cite dozens or even hundreds of sources, resulting in lengthy bibliographies.

Also, colleges often require dissertations to include additional materials like abstracts and tables of content.

What’s the Difference Between a Dissertation vs. Thesis?

Depending on the type of graduate program you enroll in, you may be required to write a dissertation or thesis. Here are the main differences between a thesis vs. dissertation .

If you want to develop your own concepts or theories, a dissertation can help you accomplish this goal.

What’s the Difference Between a Capstone vs. Dissertation?

There are doctorate programs with no dissertation. Like some online doctoral programs in education without dissertation requirements, they have a capstone project instead. Here’s a comparison of a dissertation vs. capstone .

Trapped in dissertation revisions?

How long is a dissertation, published by steve tippins on april 9, 2019 april 9, 2019.

Last Updated on: 2nd February 2024, 05:03 am

How long is a dissertation? This is a question that almost every doctoral student asks at some point. It is not a new question–in fact, it’s been asked every time a paper of some sort is assigned in any class.

The simple answer (for any paper) is, “long enough to answer the question.” Not a really helpful answer, but satisfying from a professor’s perspective.

The truth is, there is no one answer to how long a dissertation is. I can’t say 146 pages is what’s needed, as you may write to page 146 and stop without fully exploring your topic. 90 pages could adequately address your research question, or you could write 200 pages and still not fully answer what you set out to. Every topic is unique, as is each person’s writing style.

Some websites even give specific answers that are simply inaccurate. In my experience, dissertations vary too much to be pinned down like that.

However, there are some practical suggestions I can make about how long your dissertation should be, how to adequately address the requirements of each section, as well as how to expand or reduce the length of specific chapters according to your needs. I’ll explore these below.

But first, let’s try and at least give the beginning of an answer to the question “how long is a dissertation?”

Marcus Beck Sets Out to Answer “How Long Is A Dissertation?”

Any discussion of dissertation length must include the work done by Marcus Beck . As a way to distract himself from his own dissertation writing, Beck calculated the average length of dissertations in the University of Minnesota database.

infographic outlining the different Average Dissertation Lengths

You can see from looking at his data that average length varies by discipline. So the first answer to how long a dissertation is, is that it depends upon what area you are writing your dissertation. It appears that a dissertation in History will be much longer, on average, than one in Chemistry. He also calculated the average across all disciplines.

Don’t be intimidated by how long the average dissertation is.

Many people look at the average length of a dissertation and get intimidated by the high page count. But, as Marcus Beck says in his blog post, “The actual written portion may only account for less than 50% of the page length.”

dissertation length by discipline

I’ve found this to be true. References, appendixes, tables and figures, page breaks, and white space all contribute to the high page count. The actual number of words you need to write is likely considerably less than the page count initially implies.

How Long Should My Dissertation Be?

Even though there’s no single answer about how long a dissertation should be, there probably is an ideal range which your dissertation falls into. This depends on your topic of research, but also on other factors. I’ll discuss some of these below.

Institutional Guidelines

I know of schools that have policies such as “Chapter 2 must be at least 40 pages long and no more than 60 pages.” Why this type of requirement? In my mind, there are two reasons.

First, they want to give some sort of guideline for students that is helpful but does not overburden faculty (a 230-page lit review is daunting to read).

Second, credibility is important. An 8-page lit review does not reflect well upon the student or the institution.

Most schools now have a dissertation template with the headings that are needed for most sections. If you take the time to completely fill in the headings with all of the relevant information, you should come up with an adequate number of pages. Remember, in academic writing, we don’t leave much to chance, we tell the reader everything.

Committee Preferences

It is likely that you will get a committee member who will give you priceless advice such as, “more is needed here.” When you get this type of comment it can be frustrating as specific feedback can be much more helpful.

Usually, what a committee member means by comments like this is that you haven’t really convinced the reader that you have fully explored the area or demonstrated a strong understanding of the material. So, expand what you are saying. Don’t imply anything, state it directly. This lets your committee know that you really do get it.

Sometimes you will get committee members giving contradictory advice. One member may want more information and another may want less. My first piece of advice is to negotiate these types of requests through your Chairperson.

This is where your Chair’s experience and guidance can be very helpful. Second, if a member really wants material included but others do not think it is very helpful, then adding the material in an appendix may make everyone happy.

Practical Suggestions For Dissertation Length, Chapter-By-Chapter

If you adequately and succinctly address each required section, you should end up with the right length for each chapter (and therefore, a dissertation of the right length). I’ll also give some rough guidelines on average page length where appropriate.

This is the introduction to your study. It is important to lay out the agenda for your research. Be sure that your problem statement, title, and research questions are in alignment (all referring to the same idea).

Chapter 1 tends to average in the 15-25 page range. If you get beyond 25 pages, you are usually including material that is better presented elsewhere in the dissertation.

Chapter 2 should thoroughly explore the existing research on your topic. However, it shouldn’t go on and on.

  • If you are looking to beef up Chapter 2, it is always helpful to add research that supports the methodology that you are planning to use.
  • If the chapter is too long, try to reduce the references you cite to those that are the most relevant and recent.

Make sure that you tell the reader what you did and how you did it. What type of analysis did you use and why? How many respondents were involved and how did you find them? The idea is to make sure that readers understand what you did and could replicate it if they want to.

As this is a plan for your research, it seems to naturally fall in the 15 to 20 page range.

The results of your study are presented here. Include all material that will help the reader understand what you found. There is a tendency to inundate the reader with tables, charts, and graphs. If they don’t directly relate to what you found or are redundant they can be included in an appendix. You don’t want to lose your reader in an avalanche of tables and numbers.

In most dissertations, it is Chapter 5 where you get to explain what the results of your research mean and the implications. This is the only chapter where you have some freedom to really express your opinions. Go ahead and do so.

I am always surprised when someone has spent 15 months of their life working on a research topic and they submit a Chapter 5 that is 8 pages long. Spread your wings and really explore what your results mean.

Variations in dissertation length across academic disciplines

Dissertation length varies significantly across academic disciplines due to differences in research methods, data presentation, and writing conventions. Here's a general overview of how dissertation length can differ by discipline:

  • Humanities and Social Sciences: Dissertations in these fields tend to be longer because they often involve comprehensive literature reviews, detailed theoretical analyses, and extensive qualitative data. It's not uncommon for dissertations in history, literature, or sociology to exceed 200 pages.
  • Sciences and Engineering: Dissertations in the sciences and engineering might be shorter in terms of page count but are dense with technical details, data, charts, and appendices. They often range between 100 to 200 pages. However, the length can vary significantly depending on the complexity of the work and the requirements of the specific program.
  • Arts and Design: In creative disciplines, the dissertation might include a practical component (like a portfolio, exhibition, or performance) alongside a written thesis. The written component might be shorter, focusing on the conceptual and contextual analysis of the creative work, usually ranging from 40 to 80 pages.
  • Professional Fields (Business, Education, etc.): Dissertations in professional fields such as business or education often focus on case studies, practical applications, and policy analysis. These dissertations can vary widely in length but often fall in the range of 100 to 200 pages.

Dissertations vary in length due to many factors, which shows the diverse nature of academic research. Disciplinary differences are significant, as each field may have distinct expectations regarding the depth and scope of the study. 

The type of analysis conducted, whether qualitative, quantitative, or a combination of both, also impacts the length. 

For instance, qualitative studies may involve extensive textual analysis, resulting in longer manuscripts, while quantitative studies may require detailed statistical analyses. Additionally, the specific area of research within a discipline can also affect the length, as certain topics may necessitate more:

  • extensive literature reviews
  • data collection (e.g., fieldwork, surveys, interviews, lab work)
  • discussion sections

While the average length typically falls within the range of 150-300 pages, it's essential to recognize the nuanced factors contributing to variations in dissertation length. You must remain informed about the variables shaping your document's overall size and structure to deliver exemplary results.

Factors influencing the length of doctoral dissertations

Various factors determine the length of a dissertation, such as the specific guidelines set by universities, the type of research conducted, the extent of analysis required, and the presence of supplementary materials.

Several factors come into play when determining the ideal length of a dissertation. University guidelines set the tone, with institutions offering word count ranges typically between 8,000 to 15,000 words for undergraduates and masters and 75,000 to 100,000 words for PhD. 

Yet, beyond these guidelines, the nature of your research holds sway.

Disciplines vary, with humanities favoring extensive literature reviews and scientific fields emphasizing methodological intricacies. Depth of analysis matters, too; a thorough exploration demands more space. 

Balancing these elements ensures a well-rounded dissertation. So, as you embark on your scholarly journey, consider these factors carefully. By understanding them, you'll craft a dissertation that not only meets academic standards but also showcases your analytical prowess and depth of intelligence.

Length, components, and scholarly dedication

Many aspiring scholars think, "How long is a doctoral dissertation?" However, the answer isn't straightforward. Yes, length varies, but let's not forget to factor in a crucial element: time. And we know because many students have instructed us to “ write my dissertation !”

Remember, a dissertation isn't penned in one sitting. Rather, it often evolves from smaller academic chapters. This gradual process allows students to explore diverse topics before committing to a book-length project they're passionate about.

Beyond the central argument lie various components that contribute to the overall length. Take the literature review, for example—an essential segment that contextualizes the research by analyzing existing scholarship. Then there's the myriad of ancillary elements like the title page, acknowledgments, abstract, and appendix, each adding to the dissertation's page count.

It’s the accumulation of these parts that determines the length. So, while the answer may not be a precise number, it's crucial to acknowledge many elements that make up a doctoral dissertation. And for those embarking on this scholarly journey, we can help you conquer this challenge.

How Long is a Dissertation Chapter? Uncover the Mystery

When it comes to dissertation length, most grad students fret over how long each chapter should be. While there's no one-size-fits-all answer, there is a golden rule–chapters should be long enough to address the research question comprehensively. 

Think quality over quantity! Ask any dissertation adviser, and they’ll say aiming to fill a predetermined number of pages shouldn’t be the goal. Rather, you must thoroughly explore your topic, conduct extensive research, and present your findings effectively. 

Your writing style and the unique nature of your research also play pivotal roles. So, whether your chapter spans 50 pages or 150, ensure it's packed with substantive content that advances your study. Ultimately, it's not about hitting a page count but about delivering a high-quality scholarly contribution.

Dissertation Length: Pitfalls to Know

When you start writing a dissertation, it’s critical to understand that this academic paper has no strictly prescribed length. But we can speak about the average dissertation length. It depends on many factors, including:

  • Your study level
  • Type of your research
  • Number of chapters you’ll cover in your dissertations
  • Specific institutional guidelines

The overall average dissertation length is around 10,000-12,000 words for undergraduates, 15,000-25,000 words for master’s degree students, and around 50,000 words at the Ph.D. level. Some dissertations, at 70,000–100,000 words,  look like massive books!

So, How Long Is a Dissertation?

A more common way to count a dissertation length is by number of pages, not words. 

When you craft a dissertation outline , you’ll see an approximate number of chapters for your future work. Each dissertation chapter also has a prescribed length (average), so you can count the number of pages for your document.

How long should a dissertation be ?

Let’s start with dissertations by the type of research you’ll do. Here are four types:

  • Empirical involves collecting data from the real world (surveys, experiments, observations); the length of such dissertations ranges from 150 to 300 pages, depending on the depth of your collected data.
  • Non-empirical , i.e., based on existing data; these dissertations are usually 100-250 pages long.
  • Theoretical , which either develops new theories or analyzes existing ones; the length ranges from 120 to 270 pages, depending on the complexity of the theory and the depth of your exploration.
  • A case study focuses on an in-depth analysis of one specific situation (case, individual, event) and provides detailed insights into it; the length here ranges from 130 to 300 pages, depending on the depth of the analyzed case.

DISSERTATION LENGTH BY TYPE OF RESEARCH

How Many Pages Is a Dissertation?

Now that we know the average length by the type of research, let’s go on to another critical factor: your major.

Each discipline has its methodologies and expectations, which determine the research depth and the dissertation’s structure. For example, psychology dissertation topics and dissertation topics in education are often 150-250 pages. Papers in medicine can reach 350 pages, and dissertations in social sciences like history, literature, or philosophy have 400+ pages.

How Long Is a Dissertation? Let’s See by Chapters

If you look at psychology dissertation examples , you’ll see that the length of the entire document also depends on its author’s study level. It stands to reason that master’s will be shorter than Ph.D. dissertations.

A dissertation is a complex document with a highly organized structure. When writing, you include particular chapters, each with its own prescribed length. 

How long is a dissertation paper by chapters?

DISSERTATION LENGTH BY CHAPTER

A dissertation abstract is a separate page of your document, summarizing the whole paper for the audience. It highlights your research problem, describes your objectives and methodology, and presents findings, specifying the importance of your research for a scientific community.

In plain English, it’s a mini-version of your dissertation for readers to understand if your dissertation is relevant to them.

Dissertation abstracts are 150-300 words on average for undergraduates. The master’s level requires a more detailed overview, so abstracts expand to 200-500 words. At the Ph.D. level, get ready to write 300-600 words per chapter.

Introduction

It’s the start of your document. Here, you gain readers’ interest and provide background information on your topic. You’ll share the scope and importance of the subject matter, terms related to the issue, and the hypothesis you’ll reveal through your research.

What about the length of this chapter?

  • Undergraduate dissertation: 500-1,000 words
  • Master’s: 1,000-2,000 words
  • Ph.D. dissertations: 2,000-4,000 words

Literature Review

This chapter is a crucial element of all dissertations. It showcases your knowledge of theoretical frameworks and ability to synthesize and analyze existing research in conjunction with yours.

For undergraduate dissertations, write 1,500-3,000 words in your literature review. If master’s, expand it to 3,000-6,000 words.

Are you a Ph.D. dissertation writer ? Go further and present a comprehensive overview of scholarly work; write about 6,000-10,000 words for your literature review.

Methodology

This chapter describes your approach to the research, the data collection methods you used, and the analytical techniques you employed. It will showcase your ability to conduct research with valid and reliable findings to a supervisor.

The length of this chapter:

  • Undergraduate: 800-1,500 words
  • Master’s: 1,500-3,000 words
  • Ph.D.: 3,000-6,000+ words 

Results, Analysis, and Discussion

In some institutional guidelines, this dissertation component goes as two separate chapters. Here, you present and interpret your research findings, support them with relevant analysis, and encourage a discussion about their contribution to the field.

This chapter will be 1,000-2,000 words long for undergraduate papers. At the master’s level, it expands to 2,000-4,000 words, and Ph.D. dissertations have 4,000-8,000 words or more.

This chapter is a summary of your research and a reflection of your findings. It gives a reader a clear understanding of your argument and proves how your research provides a new perspective to the existing scholarly work in your field of study.

How long is a dissertation conclusion?

  • Undergraduate: 500-800 words
  • Master’s: 800-1,500 words
  • Ph.D. dissertations: 1,500-2,500+ words 

How Long Should a Dissertation Be?

Your dissertation is about content depth, not word count. While educational institutions provide length requirements, please note they are approximate: 

Don’t write for the word count; craft a concise document that covers all the necessary information without irrelevant digressions or repetitions.

How long is a dissertation? Yours will be enough with these writing tips:

  • Remove ambiguous interpretations or those unrelated to your findings
  • Eliminate idioms or any other sophisticated, lengthy phrases
  • Say no to redundant adverbs and fancy adjectives
  • Omit findings that lack data support
  • Use tables to organize repetitive information in the text

Also, provide only the necessary background information and write clear sentences without nested phrases. This will help readers digest and understand your research and perspective.

What Is The Average Dissertation Length?

Published by Alvin Nicolas at March 4th, 2024 , Revised On March 5, 2024

There is no one-size-fits-all answer when it comes to answering the question, “How long should my dissertation be?”. However, the standard is as follows. 

Shorter Dissertations

Some fields or programs may have shorter dissertation requirements, particularly in disciplines where the research tends to be more focused or where a shorter document suffices to convey the research findings. In such cases, dissertations might range from 50 to 100 pages or even shorter.

Average-Length Dissertations

For many doctoral programs, particularly in the humanities, social sciences, and some STEM fields, the average dissertation length falls between 150 and 300 pages . This length allows for a thorough exploration of the research topic , a review of literature , methodology , data analysis , and a discussion of findings .

Longer Dissertations

In certain scientific or technical fields and interdisciplinary studies, dissertations can be longer, ranging from 300 to 500 pages or more. These longer dissertations often involve extensive data collection, complex analyses, multiple experiments or case studies, and detailed discussion of results and implications.

Factors Affecting Dissertation Length

There are a number of factors that contribute to the length, including

Field of Study

Your dissertation depends on your discipline. Humanities and social sciences usually have a lower average word count compared to sciences and engineering because the latter requires extensive data analysis and experimentation. 

University Requirements

Most universities have certain specific guidelines influenced by department and faculty expectations. It is important to go through them before you start writing. 

Research Methodology

The complexity of the research design and methodology can impact the length. Dissertations having comprehensive data collection might need additional space for detailed justification. 

Literature Review

Depending on how novel your research topic is, the length of your literature review varies. If there is a lot of research done on your variables, your dissertation will be longer. 

Can a dissertation exceed recommended length?

Yes, but ensure all content is relevant and contributes meaningfully to the research.

How can I manage dissertation length effectively?

Plan meticulously, prioritize content, and seek feedback to ensure conciseness without sacrificing depth.

What’s the difference between a masters dissertation and an undergraduate dissertation.

The Masters thesis is a bridge between undergraduate study and higher level postgraduate degrees such as the PhD .

A postgraduate dissertation may not look that different to its undergraduate equivalent. You’ll likely have to produce a longer piece of work but the foundations remain the same.

After all, one of the purposes of an undergraduate dissertation or final year project is to prepare you for more in-depth research work as a postgraduate. That said, there are some important differences between the two levels.

So, how long is a Masters dissertation? A Masters dissertation will be longer than the undergraduate equivalent – usually it’ll be somewhere between 15,000 and 20,000 words, but this can vary widely between courses, institutions and countries.

To answer your overall research question comprehensively, you’ll be expected to identify and examine specific areas of your topic. This can be like producing a series of shorter pieces of work, similar to those required by individual modules. However, there’s the additional requirement that they collectively support a broader set of conclusions.

This more involved Masters dissertation structure will:

  • Give you the scope to investigate your subject in greater detail than is possible at undergraduate level
  • Challenge you to be effective at organising your work so that its individual components function as stages in a coherent and persuasive overall argument
  • Allow you to develop and hone a suitable research methodology (for example, choosing between qualitative and quantitative methods)

If the individual topics within your overall project require you to access separate sources or datasets, this may also have an impact on your research process.

As a postgraduate, you’ll be expected to establish and assert your own critical voice as a member of the academic community associated with your field .

During your Masters thesis you’ll need to show that you are not just capable of analysing and critiquing original data or primary source material. You should also demonstrate awareness of the existing body of scholarship relating to your topic .

So, if you’ll excuse the pun, a ‘Masters’ degree really is about achieving ‘mastery’ of your particular specialism and the dissertation is where you’ll demonstrate this: showing off the scholarly expertise and research skills that you’ve developed across your programme.

What’s the difference between a dissertation and a thesis?

A dissertation is a long piece of (usually) written work on the same topic. A thesis is a little more specific: it usually means something that presents an original argument based on the interpretation of data, statistics or content.

So, a thesis is almost always presented as a dissertation, but not all dissertations present a thesis.

Masters dissertation structure

As you can probably imagine, no two dissertations follow the exact same structure, especially given the differences found between Masters programmes from university to university and country to country .

That said, there are several key components that make up the structure of a typical Masters dissertation

How long is a Masters dissertation?

Most dissertations will typically be between 15,000 and 20,000 words long, although this can vary significantly depending on the nature of the programme.

You should also check with your university exactly which sections of the dissertation count towards the final word count (the abstract, bibliography and appendices won’t usually be included in the total).

Usually around 300 words long, the abstract is meant to be a concise summary of your dissertation. It should briefly cover the question(s) you aim to answer, your primary argument and your conclusion.

Introduction

The purpose of the introduction is to provide context for the rest of the dissertation, setting out your aims and the scope of what you want to achieve with your research. The introduction should give a clear overview of the dissertation’s chapters and will usually be around 1,000 words long.

Literature review

This part of the dissertation should examine the scholarship that has already been published in your field, presenting various arguments and counter-arguments while situating your own research within this wider body of work.

You should analyse and evaluate other publications and explain how your dissertation will contribute to the existing literature in your subject area. The literature review sometimes forms part of the introduction or follows immediately on from it. Most literature reviews are up to 1,000 words long.

Research methodology

Not all dissertations will require a section covering research methodology (Arts and Humanities dissertations won’t normally undertake the kind of research that involves a set methodology). However, if you are using a particular method to collect information for your dissertation, you should make sure to explain the rationale behind your choice of methodology. The word count for this part of the dissertation is usually around the 1,500 mark.

Those in the Arts and Humanities will usually outline their theoretical perspectives and approaches as part of the introduction, rather than requiring a detailed explanation of the methodology for their data collection and analysis.

Results / findings

If your research involves some form of survey or experiment, this is where you’ll present the results of your work. Depending on the nature of the study, this might be in the form of graphs, tables or charts – or even just a written description of what the research entailed and what the findings were.

This section forms the bulk of your dissertation and should be carefully structured using a series of related chapters (and sub-chapters). There should be a logical progression from one chapter to the next, with each part building on the arguments of its predecessor.

It can be helpful to think of your Masters dissertation as a series of closely interlinked essays, rather than one overwhelming paper. The size of this section will depend on the overall word count for your dissertation. However, to give you a rough idea for a 15,000-word dissertation, the discussion part will generally be about 12,000 words long.

Here you should draw together the threads of the previous discussion chapters and make your final concluding statements, drawing on evidence and arguments that you’ve already explored over the course of the dissertation. Explain the significance of your findings and point towards directions that future research could follow. This section of the Masters thesis will be around 1,500 words long.

References / bibliography

While planning and writing your dissertation, you should keep an extensive, organised record of any papers, sources or books you’ve quoted (or referred to). This will be a lot easier than leaving all of it until the end and struggling to work out where a particular quotation is from!

Appendices won’t be necessary in many dissertations, but you may need to include supplementary material to support your argument. This could be interview transcripts or questionnaires. If including such content within the body of the dissertation won’t be feasible – i.e. there wouldn’t be enough space or it would break the flow of your writing – you should consult with your supervisor and consider attaching it in an appendix.

It’s worth bearing in mind that these sections won’t always be discretely labelled in every dissertation. For example, everything up to ‘discussion’ might be covered in introductory chapter (rather than as distinct sections). If you’re unsure about the structure of your Masters dissertation, your supervisor will be able to help you map it out.

How does supervision work for a Masters dissertation?

As a Masters student at the dissertation stage you’ll usually be matched with an academic within your institution who will be tasked with guiding your work. This might be someone who has already taught you, or it may be another scholar whose research interests and expertise align well with what you want to do. You may be able to request a particular supervisor, but taught postgraduates are more likely to be assigned them by their department.

Specific arrangements with your supervisor will vary depending on your institution and subject area. They will usually meet with you at the beginning of the dissertation period to discuss your project and agree a suitable schedule for its undertaking. This timetable will probably set dates for:

  • Subsequent discussions and progress checks
  • The submission of draft chapters or sections
  • Feedback appointments

Though your supervisor is there to help and advise you, it is important to remember that your dissertation is a personal research project with associated expectations of you as an independent scholar.

As a rule of thumb, you can expect your supervisor to read each part of your dissertation once at the draft stage and to offer feedback. Most will not have time to look at lots of subsequent revisions, but may respond favourably to polite requests for exceptions (provided their own workload permits it).

Inundating your supervisor with emails or multiple iterations of draft material is best avoided; they will have their own research to manage (as well as other supervision assignments) and will be able to offer better quality feedback if you stick to an agreed schedule.

How is a Masters dissertation assessed and examined?

On most courses your dissertation will be assessed by an external examiner (as well as additional members of faculty within your university who haven’t been responsible for supervising you), but these will read and critique the work you submit without personally questioning and testing you on it.

Though this examination process is not as challenging as the oral defence or ‘ viva voce ’ required for a PhD thesis, the grading of your Masters dissertation is still a fundamental component of your degree.

On some programmes the result awarded to a student’s dissertation may determine the upper grade-band that can be awarded to their degree.

Average Dissertation Length

How long is a dissertation.

When discussing the average dissertation length it’s important to understand that it will depend upon your discipline. Most dissertations are  100 to 300 pages in length . All dissertations should be divided into appropriate sections, and long dissertations may need chapters, main divisions, and subdivisions. Source

Why Should We Care About the Ph.D. Dissertation Length?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 Ph.D. theses, the average thesis length is  between 80,000 and 100,000 words .

The average Ph.D. dissertation length in the US is around 100,000 words. This is a long read for anyone who is not familiar with the academic writing style and doesn’t have any background in the subject.

The length of a dissertation has a direct impact on the number of citations it gets in academic journals and on its success rate at conferences.

A shorter dissertation will have less depth and breadth, but it will be easier to read and more likely to be accepted by an academic journal or conference organizers.

Dissertation Length Varies by Discipline

The average dissertation length depends on the subject you’re studying. Economics and mathematics tend to have the shortest average page length, while biostatistics, history, political science, and anthropology have the longest average page counts.

The length of your dissertation will depend on the type of research, how clear your point of view is, and whether your findings are in agreement with prior theories. The conclusion section of the dissertation should be between fifteen and twenty pages, and it should make your point without being too wordy.

You should include a research findings section in your dissertation, which should not be more than 10 pages. In this section, you should state whether your hypotheses were supported or rejected, and then draw a conclusion.

Contrary to the findings section, the discussion section, which typically ranges between 15 and 20 pages, should explain the implications of your research and how it contributes to the field. It should also acknowledge the limitations of the study.

The average dissertation length at universities can vary depending on the discipline, though most tend to be between 100 and 200 pages long. You can compare average dissertation lengths by topic to see what is typical in your department.

The shortest dissertations tend to be in quantitative disciplines, while those in the humanities and social sciences have the longest averages. If you have a question about the length of your dissertation, use the graph below to find out.

Average dissertation length at universities

dissertation length by discipline

Examples of the average length of Ph.D. dissertation by major:

  • Computer Science: In the field of computer science, the average length of a Ph.D. dissertation can range from 100 to 150 pages, depending on the nature of the research topic and the inclusion of technical diagrams, algorithms, and code samples.
  • Engineering: Engineering disciplines often have longer dissertations due to the extensive research involved. On average, an engineering Ph.D. dissertation can span between 150 to 300 pages. The length can vary based on the subfield, such as civil engineering, mechanical engineering, or electrical engineering.
  • Psychology: How long is a dissertation in psychology? Doctoral dissertations in psychology typically range from 80 to 120 pages. This includes the literature review, methodology, data analysis, and discussion of findings. However, specific subfields within psychology may have variations in length.
  • Biology: Ph.D. dissertations in biology can vary depending on the area of specialization, such as molecular biology, ecology, or genetics. On average, a biology dissertation can be around 150 to 200 pages, considering the inclusion of research methodology, data analysis, and detailed scientific explanations.
  • History: In the field of history, the length of a Ph.D. dissertation can range from 250 to 400 pages. Historical research often involves extensive literature reviews, archival work, and analysis of primary sources, resulting in a comprehensive and in-depth study.
  • Literature : Doctoral dissertations in literature can vary in length based on the focus and research scope. On average, a literature dissertation may span between 150 to 250 pages, encompassing the analysis of literary works, critical interpretations, and theoretical frameworks.

Please note that these are general examples, and the actual lengths of Ph.D. dissertations can still vary within these ranges based on the specific research topic, methodology, and requirements of the academic institution.

It’s A Good Idea to Review Published Dissertations

When you’re writing your dissertation, you should always have a plan in mind. By reviewing published dissertations and discussions with your chair and committee, you can estimate the number of pages and the overall amount of content you’ll need. Remember, that less is not better, and writing more is an unnecessary waste of time. Regardless of what type of degree you have, make sure you’re writing your dissertation in a way that makes sense. Long, detailed work can save you a lot of money and time.

A student’s average dissertation length will vary depending on the topic and requirements of the university. It is important that the paper is as detailed and accurate as possible. The average dissertation length is not always the same as the average Ph.D. thesis, but it should be as comprehensive as possible. It’s also important to remember that a dissertation is not just a collection of essays. It’s an academic project.

When it comes to the average dissertation length, the length of the dissertation depends on the topic of study, design, and method. Most PhDs are based on quantitative research, while humanities and social sciences are longer dissertations using a qualitative design. The average dissertation length depends on the methods of research and how the dissertation is structured. Using a computer program, you can easily compute the average dissertation length. It’s a good idea to have a plan before you begin writing each chapter, as a rough estimate is much more likely to lead to open communication between you and your chair.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

  • master the academic foundational skills (research, writing, ability to navigate different modalities)
  • time-management skills and the ability to focus on reading and writing
  • determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

dissertation length by discipline

  • How Long Is a PhD Thesis?
  • Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

  • University of Edinburgh: 100,000
  • University of Exeter: 100,000
  • University of Leister: 80,000
  • University of Bath: 80,000
  • University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

  • Arts & Humanities: 75,000
  • Medicine, Dentistry & Health: 75,000
  • Science: 80,000
  • Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

DiscoverPhDs_How-long-is-a-PhD-Thesis_Poll

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

  • Average number of pages = 204
  • Median number of pages = 198
  • Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How Long Is A Dissertation? Here Is The Average Length

A dissertation represents the pinnacle of a graduate student’s academic journey. This extensive project requires years of study, research, writing, and editing to complete. But given its multifaceted nature, how long should a dissertation be? 

While individual requirements vary, gaining insight into typical length expectations provides helpful guidance for students undertaking this monumental effort. Let’s closely examine common dissertation lengths and chapter word counts.

Average Dissertation Length 

While specific length requirements vary, the average dissertation length falls between 80,000-100,000 words . Some succinct dissertations certainly come in under that range, but others may extend to or even surpass 100,000 words when including all core chapters, supplementary sections, back matter, citations, and references.

So realistically, most dissertation students should expect to produce a project spanning 200-300 pages by the time final revisions are complete. However, it is wise to focus more on developing robust scholarly content rather than rigidly adhering to page counts. The depth of knowledge and analysis takes priority over length.

How Long Is a PHD Dissertation? 

For a doctoral dissertation, length specifications differ based on the university and academic discipline. However, many institutions set an upper limit stipulating that dissertations should remain under 80,000 words or around 250 pages. This aims to restrain projects from becoming overly long or unmanageable.

Yet even at the maximum of 80,000 words, a PhD dissertation still greatly exceeds most other forms of academic writing. This substantial length reflects the advanced rigor and breadth of research expected for a doctoral-level project. Students must put in an immense amount of time and effort to thoroughly investigate their specialized research problem and present sophisticated analysis across multiple chapters.

Why Write a Thesis or Dissertation?

Why do graduate students undertake this intensive process? In disciplines like the humanities and social sciences, completing a dissertation is mandatory to earn a PhD. The dissertation represents an original substantive contribution to knowledge in the student’s specialized field.

This distinction arises because the student must exhibit mastery of advanced research methodologies to investigate their complex chosen research problem systematically. The project involves comprehensively reviewing the literature to establish context, identifying a knowledge gap or area needing further analysis, conducting rigorous primary research, critically analyzing findings, and drawing informed conclusions.

The final dissertation formats this long academic journey into a formal document. It involves the student’s expertise regarding disciplinary concepts, theories, models, and investigative techniques developed through their intensive program of study. The dissertation proves the student’s readiness to receive their doctoral degree based on the new knowledge their diligent efforts produced. Hence, its extensive length captures the breadth of scholarship undertaken.

How Long Is a Dissertation Chapter?

Let’s examine typical length expectations for each chapter within a complete dissertation:

Introduction

This short opening chapter ranges between 10 and 15 pages . It identifies the specific research problem or gap being addressed, the purpose or objectives of the study, the research questions and/or hypotheses proposed, and the overall significance of the topic. It also provides the necessary background context to orient readers.

Literature Review

This lengthy chapter ranges between 20 and 25 pages . It comprehensively synthesizes the scholarly literature related to the research focus. It should demonstrate command of the academic landscape surrounding the topic by organizing themes, comparing theories, revealing gaps or contradictions, and providing context for the study’s aims and methodology.

Methodology

Here, the student outlines and precisely justifies the chosen research design, data sources or collection procedures, variables examined, instruments utilized, data analysis methods applied, methodology limitations, ethical considerations, and other details needed to facilitate replication. Ranging between 10 to 15 pages , a rigorous methodology underpins valid results.

This section should not exceed 10 pages . Succinctly report key quantitative or qualitative findings derived from the research without interpretation. Use data visualizations to summarize significant patterns. Reserve extensive analysis for the discussion chapter.

In the dissertation discussion section which ranges between 15 to 20 pages , deeply analyze the implications and importance of the results within the context of prior literature and established theories in the field. Identify how the findings expand knowledge related to the specific research problem by revealing new insights, angles, or relationships.

This section ranges between 15 to 20 pages . Synthesize the overall significance of the research and the new contribution it makes to the academic discipline. Reflect on limitations and make logically justified suggestions for future work building on the study. Close with final thoughts regarding lessons learned through the intensive process.

How Long Should a Dissertation Proposal Be? 

A dissertation proposal introduces and justifies the proposed research focus for faculty approval before launching the full project. These persuasive proposals generally span 15-20 pages including a condensed introduction, targeted literature review, and thorough outline of the intended methodology. The proposal demonstrates the originality, significance, and feasibility of the impending study.

How Long Should a Dissertation Abstract Be? 

The abstract serves as a one-page overview summarizing the entire dissertation research process and findings. It highlights the core focus, methods, results, and conclusions in a condensed form, typically ranging from 150-300 words . This snapshot helps readers quickly gauge the essence of this massive project.

How Long Is a Dissertation?

Dissertation writing represents substantial scholarly undertakings that reflect the pinnacle of graduate study in academia. While individual specifications vary, they commonly exceed 80,000 words and 100 pages across several core chapters. Gaining insight into the purpose and typical length of each section helps prepare students for this enormous endeavor essential for earning a PhD in their field of study.

Undoubtedly, completing a dissertation with its expansive research and writing demands requires immense focus, perseverance, and time management skills. Yet the extensive length simply indicates the wealth of specialized knowledge a successful dissertation contributes when completed. The final work represents genuine advancement within the academic discipline.

So embrace the process and don’t become overwhelmed by worrying about length or page counts early on. Maintain focus on developing solid content demonstrating your subject matter expertise. With dedication and support, you can craft a dissertation that makes a meaningful impact, regardless of its exact length. The journey leads to enormous personal and professional growth.

How long is a Thesis or Dissertation? [the data] PhD, Masters +

Writing a thesis for your undergraduate, master’s, or PhD can be a very daunting task. Especially when you consider how long a thesis can get. However, not all theses are the same length and the expected submission length is dependent on the level of study that you are currently enrolled in and the field in which you are studying.

An undergraduate thesis is likely to be about 20 to 50 pages long. A Master’s thesis is likely to be between 30 and 100 pages in length and a PhD dissertation is likely to be between 50 and 450 pages long.

In the table below I highlight the typical length of an undergraduate, master’s, and PhD.

Level of studyPagesWords
20 – 5010,000 – 30,000
30 – 10025,000 – 50,000
50 – 45060,000 – 80,000

It is important to note that this is highly dependent on the field of study and the expectations of your university, field, and research group.

If you want to know more about how long a Masters thesis and PhD dissertation is you can check out my other articles:

  • How Long is a Masters Thesis? [Your writing guide]
  • How long is a PhD dissertation? [Data by field]
  • How to write a masters thesis in 2 months [Easy steps to start writing]

These articles go into a lot more detail and specifics of each level of study, including master’s and doctoral degrees.

Let’s take a more detailed look at the length of a thesis or dissertation. We’ll start from the very basics including what a dissertation or thesis really is.

What exactly is a thesis or a dissertation?

A thesis or a dissertation is a research project that is typically required of students in order to gain an advanced degree.

A dissertation is usually much longer and more detailed than a thesis, but they both involve extensive research and provide an in-depth analysis of their given subject.

Many people use the term interchangeably but quite often a Masters level research project results in a thesis. While a PhD research project results in a much longer dissertation.

Thesis work is usually completed over the course of several months and can require multiple drafts and revisions before being accepted. These will be looked over by your supervisor to ensure that you are meeting the expectations and standards of your research field.

PhD Dissertations are typically even more involved, taking years to complete. My PhD took me three years to complete but it is usual for them to take more than five years.

Both a thesis and a dissertation involve researching a particular topic, formulating an argument based on evidence gathered from the research, and presenting the findings in written form for review by peers or faculty members.

My Master’s thesis was reviewed by the chemistry Department whilst my PhD thesis was sent to experts in the field around the world.

Ultimately, these experts provide a commentary on whether or not you have reached the standards required of the University for admittance into the degree and the final decision will be made upon reviewing these comments by your universities graduation committee.

There are several outcomes including:

  • accepted without changes – this is where you must make no changes to your thesis and is accepted as is.
  • accepted with minor changes this is where your thesis will require some minor changes before being admitted to the degree. Usually, it is not sent back to the reviewers after the thesis defence.
  • Major changes – this is where the committee has decided that you need to rework a number of major themes in your thesis and will likely want to see it at a later stage.
  • Rejected – this is where the dissertation or thesis is rejected and the recommendation to downgrade your degree program is made.

What is the typical length of a thesis or dissertation?

The length of a thesis or dissertation varies significantly according to the field of study and institution, especially in social sciences.

Generally, an undergraduate thesis is between 20-50 pages long while a PhD dissertation can range from 90-500 pages in length.

However, longer is not necessarily better as a highly mathematical PhD thesis with proofs may only be 50 pages long.

It also depends on the complexity of the topic being studied and the amount of research required to complete it.

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field, including social sciences.  It has been created by Marcus Beck  from all of the dissertations at the University of Minnesota.

how long is a thesis

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a master’s or doctoral degree in your field. 

How Many Pages Should a Master or PhD Thesis Have? Length of a thesis?

The length of a master’s thesis can vary greatly depending on the subject and format.

Generally, a masters thesis is expected to be around 100 pages long and should include:

  • a title page,
  • table of contents,
  • introduction,
  • literature review, 
  • main test and body of work, 
  • discussions and citations,
  • conclusion,
  • bibliography
  • and (sometimes) appendix.

Your supervisor should provide you with a specific format for your dissertation or thesis that you are expected to follow.

Depending on your field of study and the word count specified by your supervisor, these guidelines may change. The student must ask their advisor for examples of past student thesis and doctoral dissertations. 

For example, if there is a limited number of words allowed in the thesis then it may not be possible to have 100 pages or more for the thesis.

Additionally, if you are including a lot of technical information such as diagrams or tables in the appendix of your dissertation or thesis, then this could increase the page count as well. For example, my PhD thesis contained a page like the one below.

This page only contains images from atomic force microscopy. Because my PhD was very visual, many pages like this exist.

Ultimately it is important to consult with your supervisor and determine how many pages your master’s thesis or PhD dissertation will be expected to have.

How long does it take to write a graduate thesis? Write your thesis quickly

Writing a graduate thesis can be a daunting task.

It is typically expected to take anywhere from one to three years, depending on the subject and scope of the project.

However, this is not just writing. A typical thesis or dissertation will require you to:

  • formulate a research question
  • do a literature review
  • create research methodology
  • perform original research
  • collect and analyse results
  • write peer-reviewed research papers
  • write a PhD/masters thesis
  • submit thesis and respond to examiners comments.

The actual writing component of a thesis or dissertation can take anywhere from one month to 6 months depending on how focused the PhD student is.

The amount of time it takes to write a thesis or dissertation can vary based on many factors, such as the type of research required, the length of the project, and other commitments that may interfere with progress.

Some students may have difficulty focusing or understanding their topic which can also add to the amount of time it takes to complete the project.

Regardless, writing a thesis is an important part of obtaining a graduate degree and should not be taken lightly.

It requires dedication and determination in order for one to successfully complete a thesis or dissertation within an appropriate timeframe.

Wrapping up

This article has been through everything you need to know about the typical length of a dissertation or thesis.

The answer to this question is highly dependent on your field of study and the expectations of your supervisor and university.

Frequently Asked Questions: How Long is a Thesis

How long is a thesis.

A thesis is typically a document submitted in support of an academic degree, presenting the author’s research and findings. The length of a thesis can vary depending on the level of study and specific requirements of the institution. It can range from 60 – 100 pages for a master’s thesis to several hundred pages for a doctoral dissertation.

What is the difference between a thesis and a dissertation?

While the terms thesis and dissertation are often used interchangeably, they can have different meanings depending on the region or academic context. In some countries, a thesis is associated with a bachelor’s or master’s degree, while a dissertation is typically required for a doctoral degree.

Is there a specific word count for a thesis?

While there is no universal word count for a thesis , institutions may provide guidelines on the expected length based on the type of degree and academic discipline. It’s essential to adhere to the specified word count to meet academic standards.

How does the length of a thesis vary across different fields of study?

The length of a thesis can differ based on the field of study and the nature of the research being conducted. For example, a thesis in the social sciences may be shorter compared to one in a scientific or technical field that requires extensive data analysis and documentation.

Decoding Academic Length: How Long Are Dissertations in Various Disciplines?

How long are dissertations? In most fields, students prepare for 100 to 200 pages, but the exact length can differ dramatically. This guide breaks down the elements that influence whether you’ll trend toward the concise end of the STEM spectrum or navigate the more voluminous humanities territory.

A dissertation project is a significant research endeavor that marks a crucial part of an undergraduate or postgraduate degree. It demands months of preparation, independent research skills, and a topic of genuine interest, varying in length depending on the subject, writing style, and academic discipline.

Key Takeaways

● Dissertation lengths vary significantly by discipline, with humanities and social sciences often producing longer dissertations due to in-depth literature reviews and theoretical analysis, while STEM field dissertations are generally more concise, focusing on data and experimental results.

● The structure of dissertations can differ across academic fields; components such as introduction, literature review, methodology, findings, discussion, and conclusion influence the length, informed by variations in research focus and methodological approaches.

● University guidelines, research nature (empirical vs. non-empirical), and logistical considerations such as inclusion of figures, tables, and appendices play critical roles in determining the final length of a dissertation.

The Spectrum of Dissertation Length Across Disciplines

The phd dissertation length varies considerably across academic disciplines, with humanities and social sciences typically requiring more extensive documents than fields like sciences. Social science dissertations, for instance, typically fall within an 80 to 120-page range. On the other hand, STEM dissertations average around 159 pages, while non-STEM dissertations average 223 pages, demonstrating a clear length distinction between these fields and academic programs.

Factors like the depth of literature review and theoretical analysis account for the variation in dissertation length across disciplines. These elements contribute to the longer lengths observed in humanities and social science dissertations in academia, compared to the oftentimes more concise dissertations in STEM fields.

Humanities and Social Sciences: A Deeper Dive

The inherent structure and focus on comprehensive literature and case studies render most dissertations from within the humanities and social sciences field typically lengthy. The expansive nature of these disciplines requires a broad exploration of existing knowledge and an in-depth analysis of various case studies, which inevitably contributes to a greater page count.

These dissertations often resemble extended essays, structured around themes explored through extensive literature and case studies. This approach necessitates a thorough evaluation of the chosen theme, often leading to a more extensive exploration of the academic discipline and ultimately, a longer dissertation.

STEM Fields: Concise and Data-Driven

Conversely, dissertations in science, technology, engineering, and mathematics (STEM) fields usually comprise articles of 100 to 300 pages. These dissertations are often more concise, focusing on the analysis of data and experimental results rather than extensive literature reviews or theoretical analysis.

In particular, quantitative dissertations, which are common in STEM fields, are often shorter, consisting of fewer than 100 pages. This brevity is primarily due to the nature of quantitative research, which relies heavily on numerical data and statistical analysis, allowing the researcher to present their findings in a more concise format.

The Structure of a Doctoral Dissertation

Another significant factor influencing the length of a doctoral dissertation is its structure. A typical dissertation includes:

● Introduction

● Literature review

● Methodology

● Discussion

● Conclusion

● References

However, the arrangement and extent of these components can vary by academic discipline, which directly impacts the overall length of the dissertation for doctoral candidates. Consultation with a dissertation advisor can provide valuable insights into these variations.

For instance, humanities dissertations may be structured around thematic chapters, each presenting a unique argument supported by specific material and analysis. On the other hand, dissertations in the social sciences often employ the IMRAD format, an entire document which includes Introduction, Methods, Results, and Discussion sections. This variation in structure influences the length of PhD dissertations, and consequently, the phd thesis requirements across different disciplines.

Crafting the Introduction

The introduction chapter of a dissertation serves as the gateway to your academic research. It should clearly present:

● the topic

● relevant facts

● the significance of the research

● the objectives of the work

Creating an engaging, insightful, and comprehensive introduction sets the stage for the following chapters of your dissertation, including the presentation of your complete theoretical framework.

While the introduction is not typically the longest chapter in a dissertation, it provides a more detailed explanation of the research’s goals and context than what is included in the abstract. The introduction’s length can thus vary depending on the complexity of the research topic and the researcher’s style.

Conducting a Thorough Literature Review

Being a critical assessment of the existing body of knowledge relevant to the research question, the literature review constitutes a substantial part of any dissertation. It involves:

● extensive reading

● analyzing the collected information

● identifying knowledge gaps

● establishing connections among various research findings.

The breadth of the literature review may lead to it occupying a substantial portion of the dissertation, particularly in areas with vast data and publications. By comprehensively reviewing existing literature, a researcher not only establishes a knowledge base but also frames the research questions that guide the remainder of the dissertation work.

Presenting Research Methods and Results

The essence of your research lies within the methodology and results sections. The methodology section should focus on:

● The methods used to conduct the research, which may involve collecting data

● Specific method and data-selection processes

● Ways of contacting the sample population

● Gathered data

● Encountered challenges

The depth of research methodologies, whether qualitative or quantitative, has a significant impact on the dissertation’s length.

On the other hand, the Results section typically should not exceed 10 pages, maximum length but this can vary based on the complexity of the research. These sections, although not necessarily extensive, provide essential insights into your research process and findings, contributing to the overall length of the dissertation.

Average Dissertation Length: By the Numbers

Given the clear variation of dissertation length across disciplines and depending on the nature of the research, how does this translate numerically? The average length of a dissertation typically falls within the range of 100 to 200 pages. This can vary based on the specific requirements of the academic institution and field of study. However, detailed disciplinary breakdowns show humanities and social sciences dissertations ranging from 200 to over 400 pages.

For example, the average length of dissertations in different fields is as follows:

● Education, environmental health, and political science: around 100 pages

● Empirical dissertations in the UK: 60,000 to 100,000 words

● Non-empirical dissertations in the UK: 15,000 to 25,000 words

It’s important to note that these are just averages and each field may have its own expectations for the document length. The range can vary widely, with the shortest recorded dissertation being 14 pages and disciplines like anthropology and history boasting some of the longest dissertations.

Empirical vs. Non-Empirical Dissertations: Size Matters

Dissertation length can be significantly influenced by the nature of the research conducted. Specifically, the difference between empirical and non-empirical dissertations is notable. Empirical dissertations involve the collection of real-world data, presenting and analyzing this data in detail. This process often requires extensive data presentation, which can increase the page count.

On the other hand, non-empirical dissertations are based on existing data or literature rather than on newly collected data. These dissertations are typically shorter as they focus on analyzing and synthesizing existing information. However, case study dissertations, which are a form of empirical dissertation, often have greater length due to their focus on in-depth analysis of a particular case or event.

The Role of University Guidelines in Dissertation Size

Not only the nature of the research and academic discipline but also university guidelines play significant roles in determining dissertation length. Specific formatting requirements can affect the layout and consequently the length of a dissertation. Universities may recommend optimal dissertation lengths with minimum and maximum page ranges, along with a suggested number of chapters to maintain proportion. Moreover, the formation of dissertation committees and the rules governing their operations, such as the review of each chapter by the committee, can lead to revisions that influence the length of a dissertation.

Even general university formatting rules that dictate aspects such as line spacing, margins, and paper quality can contribute to the overall page count of a dissertation.

Maximizing Page Count: Figures, Tables, and Appendices

Incorporating figures, tables, and appendices can notably augment a dissertation’s page count. These elements should be placed as close as possible separate page one to when they are first mentioned in the text, often contributing to a longer page count.

Tables that extend beyond one page can add additional pages to the dissertation, particularly when they adhere to margin rules which impact the layout. Similarly, additional figures and tables not placed within the main text should be included in an appendix, effectively adding subsequent pages to the dissertation’s total page count. Even statistical tables within a dissertation are typically accounted for as approximately 150 words each, thereby influencing the overall page length.

Writing Your Dissertation: Factors That Influence Length

Multiple factors influence the complex process of writing a dissertation. These factors not only impact the quality of the dissertation but also its length. Dissertations are expected to demonstrate skills expected of assistant professors, which include text analysis and scholarly engagement. These skills, when effectively applied, can influence the extent and depth of the dissertation and thereby its length.

There is no universally set number of words or pages that determine the length of a dissertation as it varies based on the university, faculty, or journal requirements. Other factors such as the subject of study, logistical considerations, and the complexity of the research being undertaken with other students can influence the length of time required to write a dissertation. Even the length of different dissertation chapters can vary significantly based on:

● the nature of the research conducted

● the data gathered

● the academic discipline

● the specific requirements of the learning institution

● the goals of the study.

The Final Stretch: Concluding Your Academic Journey

The conclusion chapter, a crucial long is a dissertation chapter, should:

● Be concise, engaging, and provide a clear understanding of the research’s main findings

● Answer the research question posed

● Signal the completion of your research

● Offer a synopsis of your hard work

● In writing the conclusion, it is written and is recommended to:

● State the answer to the main research question

● Summarize the research

● Make recommendations for future work

● Avoid repetition of the results already discussed

● Restate the research aims in a way that reflects the findings

● Leave a strong impression of the research’s contribution to the field by summarizing the most important points and situating the project in a broader context.

Navigating the world of dissertation writing can be daunting, but understanding the factors that influence its length can make the journey less arduous. From the academic discipline, research complexity, university guidelines, to the writer’s personal style - many elements come into play when determining the length of a dissertation. Remember, it’s not about meeting a specific word count, but effectively presenting your research and contributing to your field of study.

Frequently asked questions

How long is a dissertation.

Dissertation word counts vary widely across different fields, institutions, and levels of education:

  • An undergraduate dissertation is typically 8,000–15,000 words
  • A master’s dissertation is typically 12,000–50,000 words
  • A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

Frequently asked questions: Dissertation

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

  • Plan to attend graduate school soon
  • Have a particular topic you’d like to study more in-depth
  • Are considering a career in research
  • Would like a capstone experience to tie up your academic experience

The conclusion of your thesis or dissertation should include the following:

  • A restatement of your research question
  • A summary of your key arguments and/or results
  • A short discussion of the implications of your research

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

For a stronger dissertation conclusion , avoid including:

  • Important evidence or analysis that wasn’t mentioned in the discussion section and results section
  • Generic concluding phrases (e.g. “In conclusion …”)
  • Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

A theoretical framework can sometimes be integrated into a  literature review chapter , but it can also be included as its own chapter or section in your dissertation . As a rule of thumb, if your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

A literature review and a theoretical framework are not the same thing and cannot be used interchangeably. While a theoretical framework describes the theoretical underpinnings of your work, a literature review critically evaluates existing research relating to your topic. You’ll likely need both in your dissertation .

While a theoretical framework describes the theoretical underpinnings of your work based on existing research, a conceptual framework allows you to draw your own conclusions, mapping out the variables you may use in your study and the interplay between them.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

  • Your anticipated title
  • Your abstract
  • Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.

Include a note directly beneath the image acknowledging where it comes from, beginning with the word “ Note .” (italicized and followed by a period). Include a citation and copyright attribution . Don’t title, number, or label the image as a figure , since it doesn’t appear in your main text.

Definitional terms often fall into the category of common knowledge , meaning that they don’t necessarily have to be cited. This guidance can apply to your thesis or dissertation glossary as well.

However, if you’d prefer to cite your sources , you can follow guidance for citing dictionary entries in MLA or APA style for your glossary.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, an index is a list of the contents of your work organized by page number.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one to your thesis or dissertation. Your educational institution may also require them, so be sure to check their specific guidelines.

A glossary or “glossary of terms” is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. Your glossary only needs to include terms that your reader may not be familiar with, and is intended to enhance their understanding of your work.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, dictionaries are more general collections of words.

An abbreviation is a shortened version of an existing word, such as Dr. for Doctor. In contrast, an acronym uses the first letter of each word to create a wholly new word, such as UNESCO (an acronym for the United Nations Educational, Scientific and Cultural Organization).

As a rule of thumb, write the explanation in full the first time you use an acronym or abbreviation. You can then proceed with the shortened version. However, if the abbreviation is very common (like PC, USA, or DNA), then you can use the abbreviated version from the get-go.

Be sure to add each abbreviation in your list of abbreviations !

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

A list of abbreviations is a list of all the abbreviations that you used in your thesis or dissertation. It should appear at the beginning of your document, with items in alphabetical order, just after your table of contents .

Your list of tables and figures should go directly after your table of contents in your thesis or dissertation.

Lists of figures and tables are often not required, and aren’t particularly common. They specifically aren’t required for APA-Style, though you should be careful to follow their other guidelines for figures and tables .

If you have many figures and tables in your thesis or dissertation, include one may help you stay organized. Your educational institution may require them, so be sure to check their guidelines.

A list of figures and tables compiles all of the figures and tables that you used in your thesis or dissertation and displays them with the page number where they can be found.

The table of contents in a thesis or dissertation always goes between your abstract and your introduction .

You may acknowledge God in your dissertation acknowledgements , but be sure to follow academic convention by also thanking the members of academia, as well as family, colleagues, and friends who helped you.

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .  

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

In the discussion , you explore the meaning and relevance of your research results , explaining how they fit with existing research and theory. Discuss:

  • Your  interpretations : what do the results tell us?
  • The  implications : why do the results matter?
  • The  limitation s : what can’t the results tell us?

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Results are usually written in the past tense , because they are describing the outcome of completed actions.

The results chapter of a thesis or dissertation presents your research results concisely and objectively.

In quantitative research , for each question or hypothesis , state:

  • The type of analysis used
  • Relevant results in the form of descriptive and inferential statistics
  • Whether or not the alternative hypothesis was supported

In qualitative research , for each question or theme, describe:

  • Recurring patterns
  • Significant or representative individual responses
  • Relevant quotations from the data

Don’t interpret or speculate in the results chapter.

To automatically insert a table of contents in Microsoft Word, follow these steps:

  • Apply heading styles throughout the document.
  • In the references section in the ribbon, locate the Table of Contents group.
  • Click the arrow next to the Table of Contents icon and select Custom Table of Contents.
  • Select which levels of headings you would like to include in the table of contents.

Make sure to update your table of contents if you move text or change headings. To update, simply right click and select Update Field.

All level 1 and 2 headings should be included in your table of contents . That means the titles of your chapters and the main sections within them.

The contents should also include all appendices and the lists of tables and figures, if applicable, as well as your reference list .

Do not include the acknowledgements or abstract in the table of contents.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

In a thesis or dissertation, the acknowledgements should usually be no longer than one page. There is no minimum length.

The acknowledgements are generally included at the very beginning of your thesis , directly after the title page and before the abstract .

Yes, it’s important to thank your supervisor(s) in the acknowledgements section of your thesis or dissertation .

Even if you feel your supervisor did not contribute greatly to the final product, you must acknowledge them, if only for a very brief thank you. If you do not include your supervisor, it may be seen as a snub.

In the acknowledgements of your thesis or dissertation, you should first thank those who helped you academically or professionally, such as your supervisor, funders, and other academics.

Then you can include personal thanks to friends, family members, or anyone else who supported you during the process.

How Long Is a Dissertation?

When thinking about the realities of graduate school, one topic that looms large in the mind of every doctoral student is the dissertation. A dissertation is a complex document that elicits many burning questions, both from doctoral candidates and those outside of academia:

  • How long does my dissertation need to be? 
  • How much research is involved? 
  • Can I choose my own topic?
  • What does academic research actually look like, and am I capable of it?
  • What will I do with my dissertation?
  • How much time will I spend writing my dissertation?

Like many aspects of academia, the length of a dissertation is a bit complicated, and it varies by field of study. It’s determined by multiple factors, including: discipline, type of analysis (qualitative or quantitative), and the area of research. Generally speaking, the average length of a dissertation is between 150-300 pages. However, it’s important to consider a number of contributing factors. It also pays to be well-informed about variables that can influence the length of the document. 

Why Write a Dissertation?

In addition to considering the length of a dissertation, also think about what is contained within its pages, and what purpose it serves. As a key metric used to evaluate scholarly preparedness and expertise, few documents incite as much fear and anxiety as the dissertation. 

Since it represents the culmination of graduate education, the dissertation is the pinnacle of a graduate student’s research. A dissertation is an expression of years’ worth of academic training and study. In other words, it’s a pretty big deal. 

The dissertation also serves as an indicator of the student’s long-term potential as a scholar. A strong dissertation can be mined for the writer’s first few academic publications–maybe even a monograph, if the stars align. 

It generally sets the tone for the doctoral candidate’s experience on the job market and transition into their professional career, as well as within their scholarly community. The dissertation is also most students’ first opportunity to find a gap in the body of knowledge and stake their claim as experts on a narrow topic. For most researchers, it’s their first foray into primary investigation and a major project of their own. 

Dissertation Length By Discipline

Types of Dissertations

When asking how long a dissertation is, one of the first things to consider is the field of study. Most dissertations are the product of either quantitative or qualitative research, or a hybrid of both. When thinking about length, first consider the research methods that will be used. Is your research primary or secondary? Qualitative or quantitative? The answer will offer insight into how much you can expect to write. 

How Long Are Quantitative Dissertations?

Doctoral candidates in academic disciplines that rely on quantitative research, like scientific studies and analyses of human behavior, tend to produce shorter dissertations. Fields like chemistry, biology, and some social sciences are driven by statistical analysis of primary research. 

This means they adhere to methods-based practices and studies that follow a clear, linear trajectory. Likewise, researchers in fields like economics, business, psychology, and health sciences may defend dissertations that are fewer than 100 pages long. 

How Long Are Qualitative Dissertations?

In academic disciplines that use qualitative research to add to the body knowledge, it’s a very different story. Fields like history, which have a notoriously lengthy process for completing the dissertation and earning the Ph.D., are known for producing dissertations that are well over 300 pages, often stretching to 400 pages or more. These dissertations are a compilation of secondary and tertiary materials, documents, images, and hundreds of references acknowledging thousands of pages read and consulted during the research process. 

Sounds exhausting, right? It is, but there are benefits to writing a longer dissertation. The good news is that dissertations of this length and scope often produce enough research for multiple scholarly journal articles and conference papers. Rather than having just one study to publish, writers that complete dissertations in fields like anthropology, theology, art history, and literature will have several articles and conference presentations ready to go. With such a competitive job market, particularly with post-docs and tenure track positions , the more prepared scholars are to start publishing, the better. 

Creative Dissertations

When thinking about how long a dissertation is, another, lesser-known variant to consider is the creative dissertation. Though still comparatively small, a growing number of programs are offering this option to students in creative fields. 

In what is best-described as a hybrid model of original creative work presented within the theoretical framework of a critical introduction, creative dissertations have been embraced by poets, fiction writers, and essayists who have made a place for themselves within academia. These dissertations are book-length manuscripts that typically clock in around 200 pages.

So how long is a dissertation? Length varies, as we’ve discovered, but you should also think about how long you have to write it. There’s a common assumption that a dissertation is a singular document, written all at once. 

Not true! Dissertation chapters , especially in qualitative research, often get their start as final papers in academic seminars. This gives students an opportunity to dip their toes into a variety of topics before diving into one they love and committing to a book-length project. 

When thinking about how long a dissertation is, also consider all the parts of the project that are not the writer’s central argument. Many dissertations will include a literature review. This is an overview of existing publications used to illustrate a gap in peer-reviewed scholarship that will ideally be filled by the dissertation. There is also a lot of minutiae that adds to the page count of a dissertation, including:

  • Acknowledgements 
  • Introduction

Long story short, it all adds up. 

How Long Is a Dissertation? Summary

Keep in mind that dissertation lengths vary by field. Here’s what to expect: 

  • Quantitative Dissertations (math, science, psychology, physics, etc.)–100-150 pages. 
  • Quantitative Dissertations (history, art, linguistics, literature, etc.)–150-300+ pages. 
  • Creative Dissertations (fiction, poetry, memoir, translation, etc.)–150-200 pages.

Length of the average dissertation

dissertation length by discipline

On R is My Friend, as a way to procrastinate on his own dissertation, beckmw took a look at dissertation length via the digital archives at the University of Minnesota.

I’ve selected the top fifty majors with the highest number of dissertations and created boxplots to show relative distributions. Not many differences are observed among the majors, although some exceptions are apparent. Economics, mathematics, and biostatistics had the lowest median page lengths, whereas anthropology, history, and political science had the highest median page lengths. This distinction makes sense given the nature of the disciplines.

I was on the long end of the statistics distribution, around 180 pages. Probably because I had a lot of pictures.

As I was working on my dissertation, people often asked me how many pages I had written and how many pages I had left to write. I never had a good answer, because there’s no page limit or required page count. It’s just whenever you (and your adviser) feel like there’s enough to get a point across. Sometimes that takes 50 pages. Other times it takes 200.

So for those who get that dreaded page-count question, you can wave your finger at this chart and tell people you’re somewhere in the distribution.

As a student at Minnesota, I’m not sure our digital archive is representative, as it is optional, and and certain fields are more or less likely (either due to subject matter, or internal politics) to include their works within the archive. Other than that, this is neat!

what do the colors mean? at first glance I thought the colors had to do with subject area, but on closer examination that are same colored major that are very different (i.e. anthropology/aerospace engineering,

The colors look like they are reverse alphabetical.

Kyle, thanks – I figured I was missing something super simple – its been a long day. So the colors are meaningless then?

Yes, the colors are useless. They convey no information that is not already transparently conveyed.

For that matter, the box plot itself is thoroughly obsolete. Read Edward Tufte’s books, specifically chapter 6 of “The Visual Display of Quantitative Information” for the description of the successor to the box plot.

As for the topic of the post, my math dissertation was 88 pages. My advisor’s was (not a typo) 23 pages, double-spaced, including front matter and references.

And Presburger’s was 19 pages or so. But his supervisor, Tarski, would not give him his PhD. He thought the thesis was too short. So there is a lower bound.

would be interesting to see if they have been getting longer over time and by how much by subject

The chart would be more useful if the majors were ordered by median or average dissertatin length. But it is interesting to note that the more mathematical and objective the mayor, the less pages needed. Llongest dissertations: sociology and anthropology. Shortest: biostatistics.

Out of curiosity, Nathan, what was your dissertation on? (Not that I’d understand it anyway!)

Then, there are the departments’ or universities’ format standards. Single spaced? Double spaced? That, of course doubles the plage length. Better, what was the word count in the dissertations?

So with the current trend of dissertation chapters being prepared/formatted as manuscript submissions for journals up front (which have limits to the manuscript length), I would expect to see overall dissertation lengths get shorter over time (to present). Mine started out much longer, but as I started conforming to target journal format standards, I would say the overall length was reduced by a third or so. Is this true outside of ecology as well?

Oh, dear, my dissertation wouldn’t even appear on this chart, but would be off the right edge. And yes, I’m in one of the ‘runs long’ disciplines. Then again, my opus would count as short for, say, a German Habilitation or a French These d’Etat in my field, so it all depends!

This is very interesting. One variable that isn’t accounted for, but varies greatly between institutions and individual authors, is the number of words per page – determined by spacing, margins, font size, and so on. A more helpful plot would count theses by words, instead of pages, as a measure of content.

How Long Is a Dissertation? Here’s the Average Length

How Long Is A Dissertation

How long is a dissertation? This is a question that you’re likely to ask if you’ve just enrolled for a doctoral program. But, this question is not new because other students have asked it too. Perhaps, the simplest answer to this question is that a dissertation should be sufficiently long to answer the stated question satisfactorily.

How Long Is a Dissertation?

There is no single answer to the question of a doctoral dissertation length. But most dissertations are on average 100-200 pages long. Somebody can say it should be 146 pages while somebody else can say 90 pages. Another person can say it should be 200 pages. Essentially, the length of this important academic document should depend on the topic, writing style, and goals of the writer.

Universities require students to write dissertations when pursuing masters and PhD degree programs. This paper forms an invaluable part of these academic programs in reputable learning institutions. As such, most undergraduate students are worried about the length of this document because it forms an important aspect of their academic life.

There are generally practical suggestions about how long should a dissertation be. For instance, the areas that your dissertation project focuses on should influence its length. For instance, a dissertation on a history topic will most likely be longer than an average dissertation on a chemistry topic. That means your academic discipline will influence the length of your dissertation.

How Long Is a PhD Dissertation?

Most academicians say that a PhD dissertation length should not exceed 80, 000 words . Thus, your text should be near this length. This word count includes the appendices while excluding references, footnotes, and bibliography. The footnotes of a dissertation shouldn’t exceed 20% of the text.

Students are discouraged from including discursive footnotes. What’s more, they should not use footnotes to include materials that should be in their main text. Doing so would circumvent the average length of the dissertation.

The statistical tables of a dissertation are counted as around 150 words each . But, the Degree Committee can allow learners to exceed the limits after application and under exceptional situations. Therefore, students should apply for this exception early before the date they propose to submit their thesis. The Graduate Committee evaluates the application and decides whether to allow the student to alter the average dissertation length.

The committee considers the dissertation proposal, as well as, a signed statement attesting to their proposed dissertation length. If they don’t and their dissertation exceeds the average length, it will be referred back for revision before it is forwarded to the institution’s examiners.

Average Dissertation Length

Many factors should generally be considered when answering the question of how long is a PhD dissertation. However, students should limit their writing between 80,000 and 100,000 words . On average, this document should have around 204 pages. But, the average length of a PhD thesis also depends on the university and the specific subject.

Essentially, a university can set the requirements of a dissertation, including the length. Nevertheless, most institutions opt for around 100,000 words. Research has shown that STEM dissertations have a medium length of 159 pages. Non-STEM dissertations, on the other hand, have a medium length of about 223 pages. Thus, there is a significant difference in length between STEM and non-STEM dissertations.

How Long Is a Dissertation Chapter?

Another question that might be lingering in your mind is how long is a dissertation chapter? Well, this varies because each chapter is a separate section that should address something specific. If you include the right information succinctly and adequately, your final write-up should have the right length. So, how long is a doctoral dissertation in every section? Here is a rough estimate.

Introduction

This section of a dissertation should tell readers why the topic is important. It should also mention relevant facts about the topic. Essentially, the introduction should tell readers why you have chosen the topic or issue and what makes it relevant. On average, the introduction should be between 10 and 15 pages . This is a perfect size because it allows you to mention everything concisely. Focus on intriguing the audience without disclosing or revealing anything in detail. Thus, your dissertation introduction should be more of a teaser.

Literature review

This is the section where you analyze relevant sources that you have chosen for your paper. It should include only sources that can be used to write the dissertation. In this section, you analyze and point out the strengths and weaknesses of your chosen sources. The literature review should be between 20 and 25 pages long.

Methodology

The length of this part of a dissertation ranges from 10 to 15 pages . It focuses on the methods used to conduct the research. Here, you discuss the specific method and data-selection processes used. This section also includes ways of contacting the sample population, as well as, the gathered data. What’s more, the encountered challenges can be included.

This section of a dissertation should not exceed 10 pages . It features the list and clarification of the obtained findings. Research findings are mentioned alongside the hypotheses explicitly. For instance, you should state whether they were refuted or confirmed. This section should also include a conclusion for everything done as far as your investigation is concerned.

This is also called the discussion section. Its length should range between 15 and 20 pages . This is the section where you explain the implications of your research. Provide a current and bigger perspective regarding your research. What’s more, diversify the current evidence base regarding the topic. Also, provide recommendations while acknowledging limitations in this section.

So, how long is a dissertation chapter? Well, it boils down to factors of the topic, learning institution, and goals of the study. Each section varies in length based on the nature of the research conducted and gathered data.

But, exactly how long does a dissertation have to be? There is no clear answer to this question. However, psychology, history, communication, nursing, and management dissertation can be up to 300 pages long. Education, Environmental Health, and Political Science dissertations can be around 100 pages. Overall, this length is influenced by the nature of the conducted research and the data that must be included in the document.

How Long Should a Dissertation Proposal Be?

You’re no longer asking how long is a dissertation word count because this question has been answered. But, you probably want to know the length of its proposal. Well, there is no specific length for this document. However, it should be considered as a long, formal treatise.

Well, most faculties recommend between 15 and 20 pages . However, the length of a proposal should depend on factors like the problem to be pursued, reasons to address the problem, where the answers will come from, and why you will go for certain sources.

This document proposes the work to be done. The focus of this text should be on convincing the thesis committee of your faculty that you have a research question that’s worth pursuing. Thus, you must present a convincing document for your faculty to allow you to proceed with the dissertation writing project. So, how long should it be?

How Long Should a Dissertation Abstract Be?

Lastly, you may want to know how long the abstract section of your dissertation should be. This is a separate page of the entire document. It is a summary of the dissertation. It reports the outcomes and aims of the research. Essentially, readers should know what your document is all about by reading the abstract. As such, this section should be written at the end. It should state the research objectives, problem, methods, key results, and the conclusion.

The dissertation abstract length ranges between 150 and 300 words . But just like with the main sections of a dissertation, there is a strict limit on the number of words that can be included. Therefore, check with the journal or university for which you are writing the dissertation.

Your faculty committee supervises the intellectual content of your manuscript and your committee chair will guide you on the arrangement within the text and reference sections of your manuscript. Consult with your committee chair early in the preparation of your manuscript.

The specifications in the following pages were developed in consultation with University Library. These standards assure uniformity in the degree candidates’ manuscripts to be archived in the University Library, and ensure as well the widest possible dissemination of student-authored knowledge.

If your research activities involve human or animal subjects, you must follow the guidelines and obtain an approved protocol  before you begin your research.  Visit our web page for more information  or contact the Committee for the Protection of Human Subjects ( http://cphs.berkeley.edu/  or 642-7461) or the Animal Care and Use Committee ( http://www.acuc.berkeley.edu/  or 642-8855).

In addition to the considerations explained below, your Expected Graduation Term (EGT) must match the term for which you intend to file. EGT can be updated at any time using an eForm available in CalCentral.

To be eligible to file for your degree, you must be registered or on approved Filing Fee status for the semester in which you file. We encourage you to file your dissertation as early in the semester as you can and to come in person to our office to submit your supporting documents. If you cannot come to our office, it is helpful if you have a friend bring your documents. The deadline to file your dissertation in its final form is the last day of the semester for your degree to be awarded as of that semester.

Filing during the summer has a slightly different set of eligibility requirements. If you were fully registered during the immediately preceding Spring semester, and have not used Filing Fee already, you may file your dissertation during the summer with no additional cost or application required. Summer is defined as the period from the day after the Spring semester ends (mid-May) until the last day of the Summer Sessions (mid-August).

International students completing a degree in the Summer should consult Berkeley International Office before finalizing plans, as in some cases lack of Summer enrollment could impact visa status or post-completion employment.

If you have already used Filing Fee previously, or were not registered the preceding Spring semester, you will need to register in at least 1.0 unit in Summer Sessions in order to file.

Dissertations filed during the summer will result in a summer degree conferral.

You must be advanced to candidacy, and in good standing (not lapsed), in order to file.

All manuscripts must be submitted electronically in a traditional PDF format.

  • Page Size : The standard for a document’s page size is 8.5 x 11 inches. If compelling reasons exist to use a larger page size, you must contact the Graduate Division for prior approval.
  • Basic manuscript text must be a non-italic type font and at a size of 12-point or larger. Whatever typeface and size you choose for the basic text, use it consistently throughout your entire manuscript. For footnotes, figures, captions, tables, charts, and graphs, a font size of 8-point or larger is to be used.
  • You may include color in your dissertation, but your basic manuscript text must be black.
  • For quotations, words in a foreign language, occasional emphasis, book titles, captions, and footnotes, you may use italics. A font different from that used for your basic manuscript may be used for appendices, charts, drawings, graphs, and tables.
  • Pagination:  Your manuscript is composed of preliminary pages and the main body of text and references. Page numbers must be positioned either in the upper right corner, lower right corner, or the bottom center and must be at least ¾ of an inch from the edges. The placement of the page numbers in your document must be consistent throughout.

Be Careful!  If you have any pages that are rotated to a landscape orientation, the page numbers still need to be in a consistent position throughout the document (as if it were printed and bound single-sided).

Do not count or number the title page or the copyright page. All other pages must have numbers. DO NOT SKIP PAGE ” 1 “. The remaining preliminary pages may include a table of contents, a dedication, a list of figures, tables, symbols, illustrations, or photographs, a preface, your introduction, acknowledgments, and curriculum vitae. You must number these preliminary pages using  lower case Roman numerals  beginning with the number “i” and continue in sequence to the end of the preliminary pages (i, ii, iii, iv, v, etc.). Your abstract must have  Arabic numeral  page numbers. Start numbering your abstract with the number “1” and continue in sequence (1, 2, 3, etc.) The main body of your text and your references also use Arabic numerals. Start the numbering of the main body with the number “1” and continue in sequence (1, 2, 3, etc.), numbering consecutively throughout the rest of the text, including illustrative materials, bibliography, and appendices.

Yes! The first page of your abstract and the first page of your main text both start with ‘1’

  • Margins:  For the manuscript material, including headers, footers, tables, illustrations, and photographs, all margins must be at least 1 inch from the edges of the paper. Page numbers must be ¾ of an inch from the edge.
  • Spacing:  Your manuscript must be single-spaced throughout, including the abstract, dedication, acknowledgments, and introduction.
  • Tables, charts, and graphs  may be presented horizontally or vertically and must fit within the required margins. Labels or symbols are preferred rather than colors for identifying lines on a graph.

You may choose to reduce the size of a page to fit within the required margins, but be sure that the resulting page is clear and legible.

  • Guidelines for Mixed Media:  please see Appendix B for details.

Certain pages need to be formatted in a very specific way. Links are included here for examples of these pages.

Do not deviate from the wording and spacing in the examples, except for details applicable to you (e.g. name, major, committee, etc.)

  • As noted in the above section on pagination, the abstract must be numbered  separately with Arabic numerals starting with ‘1’
  • If you have a Designated Emphasis, it must be listed on your abstract.
  • IMPORTANT: A physical signature page should no longer be included with your dissertation. Approvals by your committee members will be provided electronically using an eForm.
  • The title page does not contain page numbers.
  • Do not bold any text on your title page.
  • The term and year listed on the title page must be the term of your degree. If you filed during the summer, write  Summer .
  • The yellow bubbles in the sample are included for explanatory purposes only. Do not include them in your submission.
  • If you have a Designated Emphasis, it must be listed on your title page ( DE Title Page Sample )
  • If you are receiving a joint degree, it must be listed on your title page ( Joint Title Page Sample )

The proper organization and page order for your manuscript is as follows:

  • Copyright page or a blank page
  • Dedication page
  • Table of contents
  • List of figures, list of tables, list of symbols
  • Preface or introduction
  • Acknowledgments
  • Curriculum Vitae
  • Bibliography

Please do not include an approval/signature page.

After you have written your dissertation, formatted it correctly, assembled the pages into the correct organization, and obtained verbal approval from your committee, you are ready to file it with UC Berkeley’s Graduate Division.

  • Step 0: Confirm your eligibility to file. Your Expected Graduation Term (EGT) must be current term (i.e. the term in which you expect to file your dissertation). If you need to update your EGT you can use the eForm available in CalCentral. Once your EGT is correct, you will see a number of checklist items (“Tasks”) created for you in CalCentral. You use these checklist items to proceed with filing.
  • Step 1: Convert your dissertation into a standard PDF file.
  • Step 2:  Upload your PDF to ProQuest/UMI ( http://www.etdadmin.com ) Follow the instructions on the site. NOTE: DO NOT UPLOAD A DRAFT.  Once your dissertation has been submitted, you will not be allowed to make changes. Be sure that it is in its final form!
  • Step 3:  When you have successfully submitted the document, a message will be sent to the Graduate Degrees Office to review it on-line.  After Degrees staff has reviewed it you will either receive a message that the manuscript has been accepted or that you need to make further changes. If you need to make more changes, you will need to edit your manuscript, create a new PDF, and resubmit it to ProQuest.  Degrees staff will then need to review it again. An email approval will be sent to you once the manuscript is accepted.
  • Step 4: There are two surveys to be completed:the Survey of Earned Doctorates and the Berkeley Doctoral Exit Survey. You will find these surveys as “Tasks”in your CalCentral dashboard (as long as you have a current-term EGT). Follow the instructions to complete the surveys and enter the verification codes. You should see the checklist items complete automatically.
  • Review the your committee and email addresses listed — the form will route to each of your committee members for approval.
  • If you chose to embargo your dissertation, you will not receive any copies you order from ProQuest until the embargo is lifted.
  • Once the form has been filed, you may not make any changes to your embargo selections
  • Attach a copy of the approval letter for your study protocol from the Committee for Protection of Human Subjects, or the Animal Care and Use Committee if your research involved human or animal subjects.

A Note on Deadlines

You must upload your electronic dissertation AND submit your final signature eform before 5 p.m. on the last day of the term. Both of these steps must be done before the deadline, regardless of whether your submission has been reviewed and approved. We can not provide a receipt of filing until your dissertation has been reviewed and accepted (which can take up to 4 business days), but you will get credit for the date of first submission.

If you plan use of your own previously published and/or co-authored material in your manuscript, your committee chair must attest that the resulting dissertation represents an original contribution of ideas to the field, even if previously published co – authored articles are included, and that major contributors of those articles have been informed.

Previously published material must be incorporated into a larger argument that binds together the whole dissertation. The common thread linking various parts of the research, represented by individual papers incorporated in the dissertation, must be made explicit, and you must join the papers into a coherent unit. You are required to prepare introductory, transitional, and concluding sections. Previously published material must be acknowledged appropriately, as established for your discipline or as requested in the original publication agreement (e.g. through a note in acknowledgments, a footnote, or the like).

If co-authored material is to be incorporated (whether published or unpublished), all major contributors should be informed of the inclusion in addition to being appropriately credited in the dissertation according to the norms of the field.

If you are incorporating co-authored material in your dissertation, it is your responsibility to inform major contributors. This documentation need not be submitted to the Graduate Division. The eform used by your committee chair to sign off on your dissertation will automatically include text indicating that by signing off they attest to the appropriateness and approval for inclusion of previously published and/or co-authored materials. No addition information or text needs to be added.

Publishable papers and article-length essays arising from your research project are acceptable only if you incorporate that text into a larger argument that binds together the whole dissertation or thesis. Include introductory, transitional, and concluding sections with the papers or essays.

You own copyright in your dissertation. Copyright is automatically created once your work is fixed in a tangible medium (such as saved on your computer hard drive or in cloud storage). Thus, you do not need to register copyright in your dissertation in order to be the copyright holder.

However, registering copyright in your dissertation has certain advantages: First, if your work is registered, you have evidence that you are indeed the author and owner. Second, registration allows greater enforcement of your copyright against an infringer or plagiarist, making available statutory damages set out in Title 17, Section 504 of the U.S. Code, which range from $750 – $150,000 plus attorney fees per copyright infraction. Accordingly, UC Berkeley recommends that you register copyright for your dissertation. You can register copyright through the Copyright Office’s website, www.copyright.gov , for a fee of $35, or through the ProQuest ETDAdmin system when you submit your PDF; doing so through ProQuest costs $55.

You continue to own copyright in your dissertation unless and until you transfer your copyright to another party. By complying with the UC Berkeley Graduate Division’s publishing policies, you are permitting the university to make available a copy of your dissertation online in eScholarship, but you are not transferring your copyright. You grant a similar permission to ProQuest/UMI, the exact terms of which are governed by the agreement with ProQuest you sign in the online submission process. You may request delays (i.e. embargoes) in the release of your dissertation both on eScholarship and in ProQuest. Please see “Publishing Your Dissertation; Embargoes”.

If you are including content in your dissertation not authored or created by you, be sure to consider copyright issues. The University Library can help guide you as you consider these questions. For more detail, please consult the Library’s helpful online guide, entitled Copyright and Publishing Your Dissertation .

To briefly summarize:

  • If the content is in the public domain, then you need not get any permission to use the material. For questions about the public domain, see http://copyright.universityofcalifornia.edu/use/public-domain.html.
  • If the content you wish to use is subject to a Creative Commons license of some form, you need simply abide by the term of that license. For instance, a CC-BY license means you can use the work without seeking the author’s permission, but must attribute the work to the author. For more on Creative Commons licenses, see https://creativecommons.org/licenses/.
  • If the content you wish to use is protected by copyright and no Creative Commons license governs its use, then you must consider whether your use constitutes Fair Use under 17 USC § 107. If your use of the content is a fair use within copyright law, then you need not seek the author’s permission before using it. See http://copyright.universityofcalifornia.edu/use/fair-use.html.
  • If your use of the content would exceed fair use under the Copyright Act, then you will need to seek the copyright holder’s permission in order to use the material. Be sure to request the copyright owner’s permission in writing so that you can keep track of permissions granted. Your letter to the copyright holder should make clear that you seek permission to preserve and publish the content in your dissertation through UC Berkeley’s institutional repository, eScholarship, and ProQuest/UMI. For help seeking permission, see http://copyright.universityofcalifornia.edu/use/obtaining-permission.html.

If you have additional questions about copyright and third party content in your dissertation, please contact the University Library .

UC Berkeley’s Graduate Council regulations stipulate that you have an obligation to make your research available to other scholars as part of the degree requirement.  This obligation is consistent with the long-standing principle that doctoral students share their significant scholarly contributions to advance knowledge. This requirement is fulfilled when you submit your dissertation for publishing through the ProQuest online administration system and the Graduate Division forwards your manuscript to the University Library. Your dissertation is subsequently published online in the UC system’s scholarship repository ( eScholarship ) and made available within ProQuest/UMI after your doctoral degree is officially conferred by the Academic Senate.

Making your work available to be read online immediately in eScholarship or ProQuest has many advantages. First, it clearly establishes when your work was created and published, which are powerful resources in preventing or combatting plagiarism. Others will be able to discover your prior publication. Second, it can help support your scholarly profile because people can read and begin citing your work. Citation of your dissertation by others can be offered as evidence of research significance in employment reviews. Further, research available through searches on the Internet can promote contacts that are international in scope and interdisciplinary in reach.

Occasionally, there are circumstances in which you prefer that your dissertation not be published immediately. Such circumstances may include the disclosure of patentable rights in the work before a patent can be granted, similar disclosures detrimental to the rights of the author, or disclosures of facts about persons, institutions, or locations before professional ethics would permit.

The Dean of the Graduate Division may permit the dissertation to be withheld from full-text publication in eScholarship for a specified and limited period of time. An embargo of up to 2 years can be selected on the Final Signature eForm. Once you make a selection regarding an embargo, it may not be changed. Discuss the pros and cons of withholding your dissertation with your faculty committee and departmental advisors. For more information, see the memo Advising doctoral candidates on dissertation embargoes and eScholarship repository  (PDF).

Embargoes beyond the initial 2-year option must be requested pursuant to a petition process using the E mbargo Extension Petition Form . Extensions are granted at the discretion of the Graduate Division, and are based on substantiated circumstances of the kind indicated above and with the endorsement of and an explanatory letter from the chair of the dissertation committee (or, if the dissertation chair is unavailable, the current department chair). Be sure to submit the petition form with sufficient time (at least three months) prior to the expiration of your original embargo to ensure adequate processing time prior to your dissertation’s scheduled release. If a renewal request is submitted less than three months from when the original embargo is set to expire, the Graduate Division cannot guarantee that the request will be processed and granted in time to preclude your dissertation from being made publicly available. Please note that it is your responsibility to request an extension beyond the two-year maximum from both the University and separately through ProQuest/UMI if you would like to extend your embargo both on eScholarship and on ProQuest/UMI.

Changes are normally not allowed after a manuscript has been filed.  In exceptional circumstances, changes may be requested by having the chair of your dissertation committee submit a memo to the Associate Dean and sent to Graduate Services: Degrees, 318 Sproul Hall.  The memo must describe in detail the specific changes requested and must justify the reason for the request. Such requests will not be approved for typographical errors, acknowledgments, or other minor revisions. It is your responsibility to ensure that your manuscript is in its final form before submitting it. If such a request is approved, the changes must be made prior to the official awarding of the degree. Once your degree has been awarded, you may not make changes to the manuscript.

After your dissertation is accepted by Graduate Services: Degrees, it is held here until the official awarding of the degree by the Academic Senate has occurred. This occurs approximately two months after the end of the term. After the degree has officially been awarded, the manuscripts transmitted to the University Library and to ProQuest Dissertations Publishing.

Posting the Degree to Your Transcript

Your degree will be posted to your transcript approximately 10 weeks after the conferral date of your degree. You can order a transcript from the Office of the Registrar (https://registrar.berkeley.edu/academic-records/transcripts-diplomas/).

Your diploma will be available from the Office of the Registrar approximately 4 months after the conferral date of your degree. For more information on obtaining your diploma, visit the Registrar’s website.  You can obtain your diploma in person at the Office of the Registrar, 120 Sproul Hall, or submit a form and pay the current mailing fees to have it mailed to you.

Unclaimed diplomas are retained for a period of five (5) years only, after which they are destroyed.

  • The most common mistake is following a fellow (or previous) student’s example. Read the current guidelines carefully!
  • An incorrect committee — the committee listed on your title page (and on the final signature eform you will submit) must match your currently approved committee. If you have made any changes to your committee since Advancement to Candidacy, you must request an official change from the Graduate Division. Consult your departmental adviser for details.
  • Do not use a different name than that which appears in the system (i.e. the name on your transcript and Cal Central Profile ). Students are allowed to use a Lived Name, which can be updated by self-service in CalCentral.
  • Page numbers — Read the section on pagination carefully. Many students do not paginate their document correctly.
  • Page rotation — some pages may be rotated to a landscape orientation. However, page numbers must appear in the same place throughout the document (as if it were bound like a book).
  • If you have an approved designated emphasis, it must be listed on your title page  and  your abstract.
  • Do not include the signature/approval page in your dissertation. The abstract must be  unsigned .
  • Do not include previous degrees on your title page.
  • There should be no bold text on your title page.

In May 2005, the Graduate Council established new guidelines for the inclusion of mixed media content in dissertations. It was considered crucial that the guidelines allow dissertations to remain as accessible as possible and for the longest period possible while balancing the extraordinary academic potential of these new technologies.

The dissertation has three components: a core thesis, essential supporting material, and non-essential supplementary material.

Core Thesis.  The core thesis must be a self-contained, narrative description of the argument, methods, and evidence used in the dissertation project. Despite the ability to present evidence more directly and with greater sophistication using mixed media, the core thesis must provide an accessible textual description of the whole project.

The core thesis must stand alone and be printable on paper, meeting the formatting requirements described in this document. The electronic version of the thesis must be provided in the most stable and universal format available — currently Portable Document Format (PDF) for textual materials. These files may also include embedded visual images in TIFF (.tif) or JPEG (.jpg) format.

Essential Supporting Material.  Essential supporting material is defined as mixed media content that cannot be integrated into the core thesis, i.e., material that cannot be adequately expressed as text. Your faculty committee is responsible for deciding whether this material is essential to the thesis. Essential supporting material does  not include the actual project data. Supporting material is essential if it is necessary for the actual argument of the thesis, and cannot be integrated into a traditional textual narrative.

Essential supporting material  must  be submitted in the most stable and least risky format consistent with its representation (see below), so as to allow the widest accessibility and greatest chance of preservation into the future.

Non-essential Supplementary Material.  Supplementary material includes any supporting content that is useful for understanding the thesis, but is not essential to the argument. This might include, for example, electronic files of the works analyzed in the dissertation (films, musical works, etc.) or additional support for the argument (simulations, samples of experimental situations, etc.).

Supplementary material is to be submitted in the most stable and most accessible format, depending on the relative importance of the material (see below). Any supplemental material must be uploaded to the ProQuest website under the “Supplemental Files” section.

Note . ProQuest and the Library will require any necessary 3rd party software licenses and reprint permission letters for any copyrighted materials included in these electronic files.

The following is a list of file formats in descending order of stability and accessibility. This list is provisional, and will be updated as technologies change. Faculty and students should refer to the Graduate Division website for current information on formats and risk categories.

Category A:

  • TIFF (.tif) image files
  • WAV (.wav) audio files

Category B:

  • JPEG, JPEG 2000 (.jpg) image files
  • GIF (.gif) image files

Category C:

  • device independent audio files (e.g., AIFF, MIDI, SND, MP3, WMA, QTA)
  • note-based digital music composition files (e.g., XMA, SMF, RMID)

Category D:

  • other device independent video formats (e.g., QuickTime, AVI, WMV)
  • encoded animations (e.g., FLA or SWF Macromedia Flash, SVG)

For detailed guidelines on the use of these media, please refer to the Library of Congress website for digital formats at  http://www.digitalpreservation.gov/formats/index.shtml .

Q1: Can I file my dissertation during the summer?

A1: Yes. There are 2 ways to file during the summer:

  • Register for at least 1.0 unit through Berkeley Summer Sessions. With this option, you can file any time before the summer deadline .
  • Register the preceding spring semester. As long as you were registered in the spring, and have not used filing fee before, you will be allowed to file during the summer without additional fees or applications.

Q2: If I chose that option, does it matter which session I register in during the summer session?

A2: No. You can register for any of the sessions (at least 1.0 unit). The deadline will always be the last day of the last session.

Q3: If I file during the summer, will I receive a summer degree?

A3: Yes. If you file before the end of the summer sessions, you will receive a summer degree. Remember to write “Summer” on your title page!

Q1: I’ve seen other dissertations from former students that were / that had  __________, should I follow that format?

A1: No. The formatting guidelines can be changed from time to time, so you should always consult the most current guidelines available on our website. This question is most frequently asked in regard to the issue of double vs. single spacing.

Q2: I want to make sure that my dissertation follows the formatting rules. What’s the best way to do this?

A2: If you’ve read and followed the current guidelines available on our website, there shouldn’t be any problems. You can upload your dissertation as soon as it is in its final form. If any changes are necessary, you will be given the opportunity to make them without penalties. If you’ve heard horror stories from other students about formatting changes in their manuscripts, you’ve likely been talking to past students who didn’t follow the directions and had to print out their dissertations on expensive, archival paper. Current students submit their dissertations electronically and, as such, it’s much easier and more painless to make changes!

You are also always welcome to bring sample pages into the Graduate Degrees Office at 318 Sproul Hall to have a staff member look over your manuscript.

Q3:  Does my signature page need to be printed on some special paper?

A3: Signatures are now an eForm process. A physical signature page is no longer required.

Q1: I’m away from Berkeley. Is there any way to file my dissertation remotely?

A1: Yes! The whole process is done remotely.

Q2: Can I have a friend bring my dissertation materials for me?

A2: Yes. Please see the answer above regarding filing remotely.

Q3: I read something about needing to allow 4 days to review my dissertation. So what is the actual deadline?

A3: Two things must happen before the end of the business day on the stated deadline: 1) you must have uploaded your dissertation to the ProQuest website and 2) you must have completed all the checklist items that appear in CalCentral (final signature eform and 2 surveys). Though it is not recommended, you can do both of these things on the very last day.

Q4: So what’s this thing about the 4 days?

A4: As you might expect, the Degrees Office receives hundreds of dissertations near the end of the term (in fact, half of all dissertations are submitted during the final week). This means that it may take several days for us to review your dissertation. Don’t worry. You’ll get credit for the date that you uploaded your dissertation. However, it may take up to 4 business days to review your submission and, if everything is acceptable, provide you a Receipt of Filing.

Q5: Can I do the Final Signature eForm before I upload my dissertation?

A5: Yes. We won’t be able to finalize your filing until everything has been reviewed and approved, but you are welcome to do those in any order.

Q6: What’s a Receipt of Filing? Do I need one?

A6: The Receipt of Filing is an official document that we produce that certifies that you have successfully filed your dissertation on the specified day and that, if all other requirements are met, the date of the degree conferral.

Some students may need the receipt in order to prove to an outside agency that they have officially filed their dissertation. Many students simply keep the receipt as a memento. Picking up your receipt is not required.

Q7: What’s the difference between a Receipt of Filing and a Certificate of Completion?

A7: A Receipt of Filing is automatically produced for all students upon successful filing of their dissertation. However, it only certifies that the dissertation has been accepted. The Certificate of Degree Completion  must be requested. It will state that all requirements  have  been met and notes the date that the degree will be conferred. This is a useful document for students who file early in the semester and need some verification of their degree in advance of its conferral (note: degrees are only conferred twice each year).

Q8: How do I know if I’m eligible for a Certificate of Completion?

A8: In order to be eligible to receive a Certificate of Completion, you must:

  • Successfully file your dissertation (your online submission accepted as well as paperwork turned in)
  • Have a fully satisfied Academic Progress Report (APR). The APR all the degree requirements as noted by your department. If there are requirements showing as “unmet” but you believe you have completed, please contact your GSAO.
  • Pay all of your registration fees. While it may not necessarily hold up the production of your certificate, it is important that all fees are paid before the degree is conferred.

Q9: I’m supposed to bring in my approval letter for research with human subjects or vertebrate animals, but it turns out my research didn’t use this after all. What should I do?

A9: If your research protocol has changed since you advanced to candidacy for your degree, you’ll need to ask you dissertation chair to write a letter to the Graduate Division explaining the change. It would be best to submit this in advance of filing.

Q10: My dissertation uses copyrighted or previously published material. How do I get approval?

A10: The policy on this has recently changed. There is no need to for specific approval to be requested.

Q12: I uploaded my dissertation on the last day. What if I’m told I need to make changes?

A12: This won’t be a problem. If there are formatting issues that need to be resolved, you will be notified and be given the opportunity to make revisions – even if it is a few days after the deadline. As long as your dissertation was originally uploaded before the deadline. Obviously, we won’t be able to provide you a receipt (see Q above on Receipt of Filing) until everything has been finalized.

Q13: I found a typo in dissertation that has already been accepted! What do I do?

A13: Once a dissertation has been submitted and accepted, no further changes will be permitted. Proofread your document carefully. Do not upload a draft. In extreme circumstances, your dissertation chair may write a letter to the Graduate Division requesting additional changes to be made.

Q14: Oh no! A serious emergency has caused me to miss the filing deadline! What do I do? Are extensions ever granted?

A14: In general, no. In exceptional circumstances, the Head Graduate Advisor for your program may write to the Graduate Division requesting an extension. Requests of this type are considered on a case-by-case basis and, if granted, may allow you to file after the deadline. However, even if such an exception is granted you will receive the degree for the subsequent term. Your first step is to consult with your department if an emergency arises.

How long was your thesis/dissertation?

I'm suddenly very curious about comparative lengths of theses and dissertations between disciplines (could be because I'm procrastinating finishing up my second official draft). So, if you have a moment of free time, could you tell me whether your degree, your field/discipline and the length of your document?

COMMENTS

  1. How long is a PhD dissertation? [Data by field]

    It takes many years to accumulate enough original and new data to fill out a dissertation to the satisfaction of experts in your field. Interestingly, the PhD dissertation length and content vary significantly based on the field you are studying and the publishing conventions. A PhD can be anywhere from 50 pages to over 450 pages long.

  2. How Long is a Dissertation for a PhD?

    The length of a dissertation varies by discipline, institution, and research project. Some dissertations can be as short as 50 pages, while others may total 400 pages. But the average dissertation ranges from 100 pages to 250 pages. Dissertations in the humanities and social sciences are typically the most extensive.

  3. How Long Is a Dissertation?

    The truth is, there is no one answer to how long a dissertation is.
