Theme vs. Thesis: Key Differences and How to Write each

• by Judy Jeni
• January 18, 2024

Many students confuse between these two terms, a theme and a thesis. In practice, they are two distinct aspects.

By reading the content in this write-up, you will appreciate the difference between the two items. A theme is a central message in a text, whereas a thesis is an argument about a text.

Theme vs. Thesis

While it is possible to write items based on a theme or a project based on a thesis, the two are different. While their focus may seem similar, they are different.

A theme is a focus topic that a writer bases his argument on. It is the direction that guides the points that a writer argues. On the other hand, a thesis is a stand that a writer seeks to prove in his or her writing.

In a theme, a writer bases points on a concept, but in a thesis, the writer writes to prove a specific assertion.

A theme and a thesis are two different items that we can elaborate through the following points:  

• A theme is the crucial idea of the piece of literature or any art you are writing about.
• It is the recurrent idea in your work before you identify other elements such as characters, conflict, setting, and plot.
• A thesis is a statement that you will try to prove by backing it with necessary facts. It is a position that the author takes to maintain a particular argument.

Differences between a Theme and a Thesis

• A theme is the general topic of your essay, whereas a thesis is the precise statements that the author tries to prove.
• A theme could be more general as the writer cannot necessarily state it expressly. On the other hand, a thesis is a direct message at the beginning of the paragraph that indicates what the entire paper will be talking about.
• A theme is the motif of the piece or an underlying idea, whereas the thesis is the argument in favor of something that you believe you are presenting to your audience.

How to Write a Theme Based Essay

A theme-based essay writes about something based on a theme that you can derive from a novel, song, or short story. Before you begin to write such an essay, you should identify the underlying theme in your literature work.

Steps When Writing a Theme Based Essay

1. identify the character.

One should locate the characters that you will discuss in the essay. Such should relate to the identified theme in your essay.

For instance, if you locate ‘violence’ in the novel ‘The Shadow of Death,’ it is reasonable to talk about the characters that promote violence in the novel.

2. Maintain the Chosen Theme

As indicated above, suppose violence is the main theme in the novel, then you should maintain the same thing by writing about violence.  Such could include incidences of violence, including blood baths and more.

The point is you should endeavor to remain as close to the theme of violence by highlighting incidences and situations from the novel, drama, or story.

3. Avoid Mixing the Theme with the Key Subject

A theme is not a plot but an idea that binds up the story. It is the message that the author wants to convey to the audience or the readers. It is, therefore, wrong to try to write on the plot or story. Stick to the idea only.

Let your thoughts remain organized and well-knitted in the essay body. In the same vein, the body should relate to the central theme as you refer to the characters and incidents in the source matter.

How to Write a Thesis

One can use the following steps to come up with a strong thesis statement:

Start with a Question

One should come up with a question in case the assignment did not offer the question.

After that, you should state your topic, which is the essential idea of the paper.

This thesis statement is usually a phrase or a few words that summarize the main subject of your paper.

The thesis statement makes the topic to be as precise as possible.

Write an Initial Answer

After performing initial research, it is now time to formulate a tentative answer. At this point, it could be just simple, or you can craft it to guide the process of writing and researching.

In case you are writing an argumentative essay, your answer should take a position on the matter. This is different from a thesis statement. Check more about thesis statements to know the idea of the two.

Develop the Answer

This section should prove why you believe it is your answer and convince the reader to agree with your position.

The more you write about the topic, the more you develop more details for your response. The final essay should summarize your overall arguments.

One should know what they are trying to prove in a topic. While you are expressing your opinion, it is vital to state one major idea. Also, you should name the topic and state something specific about it.

Furthermore, you should take a position and back it up with facts and reasons as an author. It is vital to support your reasons with evidence and logical facts.

Include Opposing Viewpoint

The correct thesis statement should acknowledge that there is another side of the argument. It is excellent to include your opposing viewpoints in your opinion. It is also essential to capture another person’s view who may have a different opinion about your topic.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

What are Thesis and Theme?

Going Back to the Basics:

Thesis and theme are two words that everyone knows they know but they typically can’t describe these terms succinctly. Chances are, unless you’re in a writing-dominated field, you probably haven’t given these terms much thought since college or high school English classes.  That’s okay, but if you’re embarking on writing a book, you’ll need to brush up on these key terms.

Thesis and theme are the foundations of all writing, professional or informal. They both convey the subject of the text. Despite this similarity, there’s a stark difference between the functions of the thesis and the theme. 

The theme of a piece of writing is less intricate than its thesis. A theme is the main idea of a paper. It can be described in a word or short phrase, and these themes are demonstrated throughout the work by the content. Within a longer piece, such as an article or a book, there can be multiple themes. Oftentimes, these are divided by chapters or headings. Theme offers some room for interpretation—while the overall message should be received the same by each reader, the word(s) they use to describe it has some flexibility.

That’s not the case with the thesis statement. A thesis statement is the argument that a writer constructs throughout the work. It can be described in a phrase, sentence, or even a paragraph. The thesis statement must define the purpose of the paper, mention the points you’ll explore, and serve as an abbreviated summary of the work. There’s the misconception that a thesis statement and a topic sentence are interchangeable terms. While the thesis statement may act as a topic sentence, it usually comes later in the introductory text and it’s more specific than topic sentences are allowed to be.

A strong thesis requires some effort and workshopping. When you’re writing the outline for your book, determine the core ideas that you want to discuss, think about your purpose for writing, and then find a way to piece all of the components together. A key to obtaining a good thesis is to unify your key points and be specific about your intentions for the piece. 

Let’s take a look at an example: 

A paper on traditional vs independent publishing can have themes of diversity, empowerment, change through social media, individual identity, etc. Subheadings would show these themes for each of the sections throughout the paper.

A topic sentence could be: “In the internet age, small independent publishing is growing as an alternative for authors .”  This is a fact that can be proven; it doesn’t show the author’s opinion or intention for the paper.

But a thesis statement would be: “ Small presses use social media as a tool to celebrate the diverse voices that they publish while enacting slow scale social change through challenging identities perpetuated by the media.” Now that thesis encompasses a lot of topics that the reader will expect to have reviewed. It also makes an argument for how small presses operate and what their lasting effects might be. 

Your thesis should be just as specific, though it doesn’t have to be as polished and complete before you start writing your book. However, you should still have a placeholder thesis statement to guide you through your writing. Later, you can refine your thesis to better reflect the content you cover. I suggest having several people review your thesis statement to make sure it’s 1) clear, 2) concise, and 3) accurately describes what your book is about. If your thesis is still giving you trouble, try completing some thesis exercises, available in most writing books and online.

We understand the fundamental importance of crafting a clear and compelling thesis statement to guide your writing journey. Our experienced team is dedicated to helping you articulate your core ideas and intentions effectively, ensuring that your book’s thesis serves as a strong foundation for your narrative.

The thesis statement is a one-sentence statement that expresses the main idea of the essay. The thesis statement is an arguable statement that communicates the author’s stance on a topic to the reader. In order to better understand the differences between a thesis statement and main idea, it's important to understand the components of an essay. Essentially, it's not a “versus” situation because the thesis statement and main idea cannot exist without the other.

Purpose of the Thesis Statement

The thesis statement is the foundation of the essay because it tells the reader what the essay will be about and gives the essay direction. The goals of the thesis statement are to organize and development your argument and provide your reader with a road map or guide to your argument. The thesis statement should answer a question about the topic you are exploring as a writer. A good thesis statement will express only one main idea and will assert your conclusion about a topic.

Identifying the Main Idea

If you are given a topic to write about, it's important to first do your research and identify some main ideas associated with that topic. If you are writing about a piece of literature or specific work, you'll still need to do research but you will also need to read for key concepts or key ideas within that piece of writing first. Consider rereading the piece of literature to locate the main idea of the writer. Once you have located the main idea, you can then generate an opinion about the idea and create your thesis statement.

Developing the Main Idea

The topic of an essay is the subject, or what the essay is all about. An idea is what the writer says about the topic. The ideas include the main idea, which is then expressed in the form of a thesis statement. The main idea is not arguable like the thesis statement should be; it's simply an idea. Before writing, you should first develop the main idea because you cannot generate an arguable thesis statement about a topic until you have identified what you think of the topic.

Purpose of the Topic Sentence

The main idea of an essay is conveyed through the thesis statement and carried out through the topic sentences. An idea cannot be a statement, but a statement conveys an idea, hence the purpose of a thesis statement to state the point of an idea to convey to the reader in the development of an essay. Topic sentences also express the main idea. It's the first sentence of each subsequent paragraph in the essay and should be followed by supporting details, all supporting the topic sentence, which should support the main idea expressed in the thesis statement.

Thesis vs. Topic

As you begin to formulate a thesis for your essay, think about the following distinction between topic and thesis. A topic is a general area of inquiry; derived from the Greek topos (place), "topic" designates the general subject of your essay. For instance, "Munro Leaf's The Story of Ferdinand (1936) and Dr. Seuss's And to Think That I Saw It on Mulberry Street (1937) both respond to the rise of fascism" would be a weak thesis but a good a topic for an essay. From a topic, many specific theses can be extracted and developed. A thesis is more specific and delimited; it exists "within" your topic. In your essay, you need to use an argumentative thesis.

        In argumentative writing, the writer takes a stance and offers reasons in support of it. Crucial to any piece of argumentative writing is its thesis. The thesis arises from the topic, or subject, on which the writing focuses, and may be defined as follows:

A thesis is an idea, stated as an assertion, which represents a reasoned response to a question at issue and which will serve as the central idea of a unified composition.

        If we've selected as a topic the notion that these books show the power of unions we need to ask, "So what?" Do both stories make exactly the same argument in exactly the same way? How do they differ? How are they similar? In each tale, what are the workers' demands? With what degree of sympathy are those demands presented? In sum, what does focusing on this theme tells about what the books might mean? One possible thesis is:

If Munro Leaf's The Story of Ferdinand (1936) and Dr. Seuss's And to Think That I Saw It on Mulberry Street (1937) both respond to the rise of fascism, neither clearly articulates a political position on the subject: Although Leaf's book offers more allusions to European fascism than Seuss's does, both can be read as critical of fascism, indifferent to it, or proposing another political strategy entirely.

        When you compose a thesis statement, think about how it satisfies the following tests:

1. Is it an idea? Does it state, in a complete sentence, an assertion? 2. Does it make a claim that is truly contestable and therefore engaging? (Yes, because one could also argue for a greater difference between these two tales, or that one or both more clearly advances a particular political ideology.) 3. Are the terms you are using precise and clear? (Key terms here seem to be: "fascism," "articulates," "political position," and "critical.") 4. Has the thesis developed out of a process of reasoning?

        Once these questions have been satisfactorily answered, use the resulting thesis to organize your evidence and begin the actual writing. As you do so, bear in mind the following questions:

1. What is my purpose in writing? What do I want to prove? (Notice the explicit purpose in the thesis statement: it does not merely point out that both books show the power of organizing. Instead, the thesis takes a position on this topic, and then answers the question "So what?") 2. What question(s) does my writing answer? 3. Why do I think this question is important? Will other people think it equally important? 4. What are my specific reasons, my pieces of evidence? Does each piece of evidence support the claim I make in my thesis? 5. Where does my reasoning weaken or even stop? Am I merely offering opinions without reasoned evidence? 6. How can I best persuade my reader?

Theme vs. Thesis Statement vs. Topic Statement

by Kinglove | Writing

Related article: What is a thesis?

A thesis statement is a statement that says what you are going to argue or prove, not what you’re going to attempt to do. It’s not your plan but your argument.

Identifying a thesis

“The first thing to remember is that a thesis is the  point the author is trying to prove .  That means that a topic, which can be expressed in a phrase, like “alcoholism” or “effect of corruption on poverty,” is  not  a thesis.  A thesis can only be expressed by a complete, declarative sentence  (not a question, either). So be sure to write out a complete sentence when identifying the source’s thesis. (Review “ What is a Thesis ” for more details.)

Often all you need to identify the thesis of an article is the  abstract —the brief summary, usually just a short paragraph, provided with the listing of many articles in most databases. This explains the main idea of the article and states what point it is trying to prove.

However, an abstract is not always provided. In those cases, you may need to read the first few paragraphs to get the gist of the article. This is typically where the author will lay out the argument and, again, state the point that they are trying to prove. In more difficult cases it may be necessary to read the conclusion as well, since this is often where they sum up the argument one last time. Sometimes it’s clearer in the conclusion than in the introduction.

With books, the thesis may be stated on the back, on the jacket flap, in the preface or introduction, or early on in the first chapter. On the back and on the jacket look for phrases like “the author argues that…” In the preface, introduction or first chapter, look for “I argue…” or similar phrases.

Keep in mind:   Reference works do not have theses.  Remember the  definition of a thesis : a point that an essay is trying to prove. Reference works don’t try to prove a point. They simply report information. Usually it’s the more in-depth general interest works, and especially the scholarly sources, that have theses. So those are the ones you’ll want to focus on.” From Shoreline community college .

Merriam Webster’s dictionary:

Definition of thesis:

“a: a proposition to be proved or one advanced without proof:   HYPOTHESIS

“ 5.3 Turn Your Working Hypothesis into a Claim We described the early stages of research as finding a question and imagining a tentative answer. We called that answer your working hypothesis. Now as we discuss building an argument to support that hypothesis, we change our terminology one last time. When you think you can back up your hypothesis with good reasons and evidence, you’ll present that hypothesis as your argument’s claim . A claim is an assertion (which could be one sentence or several) that demands support. Your main claim is the assertion supported by your whole research argument. Some call this assertion your thesis. ” From the Turabian Manual, 9th Edition

Thesis Statements vs. Topic Statements

“ Thesis Statements Every paper must argue an idea and every paper must clearly state that idea in a thesis statement. A thesis statement is different from a topic statement.  A topic statement merely states what the paper is about.  A thesis statement states the argument of that paper. Be sure that you can easily identify your thesis and that the key points of your argument relate directly back to your thesis.

Topic statements: This paper will discuss Harry Truman’s decision to drop the bomb on Hiroshima. The purpose of this paper is to delve into the mindset behind Truman’s decision to drop the bomb on Hiroshima. This paper will explore how Harry Truman came to the decision to drop the bomb on Hiroshima.

Thesis statements: Harry Truman’s decision to drop the bomb on Hiroshima was motivated by racism. The US confrontation with the Soviets was the key factor in Truman’s decision to drop the bomb on Hiroshima. This paper will demonstrate that in his decision to drop the bomb on Hiroshima, Truman was unduly influenced by hawks in his cabinet.” Source: University of Mary Washington .

The theme is the central idea of a piece. It is an implicit  or  recurrent   idea in the work.

“ To identify the central idea or theme, one must also look at the other elements of fiction (plot, characters, setting, conflict, etc.) to explain how the author has tied all of these together. In order to understand the central idea or theme of the story ask yourself the following questions:

• How is the central idea or theme expressed through the characters, setting, point of view, tone, language, or conflict?
• In what way does the resolution of the external conflict indicate the central idea or theme? How does the resolution of the internal conflict express the story’s theme?
• Are symbols, metaphors, or similes used to portray the central idea or theme?
• What are the repeated images, words, or expressions in the story?
• How does the title make sense in terms of the story? Is it significant?
• What the story reveals about society, people in general, the roles of men and women, the time period in which the story takes place?
• Does the central idea make sense in light of the story and the title?

Remember, there is no one way to express the central idea of a story (but some statements are definitely better than others). The best stories have multiple levels of meaning and require MORE THAN ONE READING before the central idea becomes clear. ” http://www.austincc.edu/bvillarr/theme.htm

What is the difference between a thesis statement and a theme?

“Theme is the main idea of the piece of literature, art, film, etc.– whatever it is you are being asked to write about. It is the “lesson” that is being taught. For example, “greed” in an incomplete theme, but “greed is the root of all evil” would be a valid theme of a work.

The thesis is the actual statement in your paper that expresses what the idea behind your essay is. It is what YOUR paper is about, which in turn, is a statement that also conveys what the work being discussed is about. Therefore, a “thesis” normally contains a “theme”. An example might be: In “The Pardoner’s Tale”, Chaucer expresses through both the actions of the Pardoner as well as through the actions of the characters in his tale, the notion that greed is the root of all evil. ” Source: From Yahoo Answers

“There are some very strong parallels between both themes and thesis statements.  I think you will find there will be much in the way of responses to how each will be different.  For my bet, I would like to think of themes as something that can be found in writing that expresses the intent of what the author is trying to show.  Themes can be found in literature and other forms of writing where an idea is explored in a complex and intricate manner.  Examples of themes can be courage, the quest for justice, the collision between equally desirable, but ultimately incompatible courses of action, or the notion of identity formation. These themes are proven from a base that is not purely evidential and argumentative, which differentiates them from a thesis statement.  For example, when Homer explores the theme of equally desirable, but ultimately incompatible courses of action, he does not do so in a strictly linear and evidential manner.  Rather, he shows us a character who must endure such a theme and how it plays out is built within the development of the character.  Hektor’s character evolution is how we, as the reader, see Homer’s theme develop.

In contrast to this, a thesis statement is something that is built through evidence, analysis, and persuasion.  It seems to me to be more linear and directed than a theme.  For instance, a thesis statement can be analytical, which analyzes an idea and deconstructs it through a paper.  A thesis statement could also be persuasive, and it hopes to do so through evidence and analysis.  The websites below give examples of thesis statements.  I think I differentiate both concepts as a thesis statement trying to prove something, while a theme seeks to explore it.” Source: https://www.enotes.com/homework-help/what-difference-between-thesis-statement-theme-110021

Thesis vs. Dissertation: What’s the difference?

Thesis and dissertation are extensive research papers that differ in terms of their requirements, length, and purpose, with the former being associated with a master's degree and the latter with a doctoral degree, but are often used interchangeably.

Updated on September 15, 2023

A thesis and a dissertation are both extensive research papers, and both require literature searches and novel findings, but the two differ in various ways. Their definitions also differ across regions. Typically, in North America, a thesis is required for the completion of a master’s degree, while a dissertation is required for the completion of a doctoral degree. The former is long, while the latter is longer and more intensive.

Despite these differences, the two terms are often used interchangeably, especially among those who haven’t completed one or the other. Here, we’ll compare the components, length, and purpose of these two academic documents to clearly understand the differences between these important papers in the life of a graduate student.

What’s a thesis?

The term “thesis” explained here is generally consistent with how the word is used in North America to describe this substantive research paper.

A thesis is an extended argument (PDF). It is a research-based document that displays the student’s/author’s knowledge and understanding of a specific subject within their field of study. It generally presents findings on a particular topic. 

See this and this (PDFs) for examples. These superb master’s theses from Canada will give you an idea of the size and format of these papers.

Who would write a thesis?

You generally write a thesis if you’re undertaking a research-oriented master's degree program (as opposed to a practical program, which may require a capstone, internship, exam, etc.). 

The thesis is the essential part of a program’s research component, demonstrating the student's ability to critically analyze the literature and complete independent research. The process of writing a thesis involves exploring a specific research question, conducting a comprehensive literature review, collecting and analyzing data, and presenting findings in a structured and cohesive way.

A thesis' specific requirements and expectations differ depending on the academic institution, department, and program.

Components of a thesis

A thesis is typically presented in chapters. How many chapters will vary, but a common structure is:

• Introduction: Presents the research topic, purpose, and objectives, setting the context for the work.
• Literature review: Comprehensive survey of existing scholarly material related to the research topic, highlighting key theories and findings.
• Methodology: Describes the methods, procedures, and tools used in doing the research.
• Research: The actual performing of the study, collecting, and analyzing data relevant to the research question.
• Findings and conclusions: Gives the results obtained and explains their significance in relation to the research question.
• Limitations and future research: Outlines the study’s shortcomings and suggests potential areas for future investigation.

Within that structure, and in addition to those parts, a thesis may also include: 

• Cover page: Contains the thesis title, author's name, institution, department, date, and other relevant information
• Abstract : A brief summary of the thesis, highlighting the research objectives, methods, key findings, and conclusions.
• Certificates of own work
• Certificate of readiness to be included in the library
• Certificate that the research has not been presented to another university
• Acknowledgments
• Table of contents: List of the main sections, subsections, and corresponding page numbers.
• Index of figures and tables
• References: A comprehensive list of all the sources cited in the thesis, following a specific citation style (e.g., APA, MLA).
• Appendices (optional): Additional materials include:
• Abbreviations and/or acronyms used
• Questionnaire or interview schedule/s (if used)
• Data acquired in the form of transcripts or numeric tables
• Research protocol
• Ethics protocol

What’s a dissertation?

This is also viewed from a North American perspective, where a dissertation is usually the main research work toward completing a research-based doctoral program.

A dissertation is a comprehensive and in-depth research project completed as part of the requirements for a doctoral degree. It’s a substantial piece of original work that contributes new knowledge to a specific field of study.  Naturally, when it’s completed as the major requirement for earning a PhD, it’s longer, more detailed, and the expectations are higher.

Dissertations themselves can add to the literature in the field. For this reason, some students choose to publish them and have them indexed. The research and the data acquired while working on a dissertation can potentially lead to more publications and help define the researcher’s growing area of expertise.

See this and this (PDFs)  top-ranking dissertation on ProQuest for good examples.

Who would write a dissertation?

Completion and defense of a dissertation is a standard requirement for doctoral students to earn a PhD or another doctorate such as an EdD or DM. But some specialized degrees, such as a PsyD (Doctor of Psychology), JD (Juris Doctor) or DPT (Doctor of Physical Therapy) may have practice-based requirements in place of a research project, as these courses of study are geared more toward practical application.

Components of a dissertation

A dissertation’s components are generally the same as those of a thesis. You can look at the list above for a thesis to see what typically goes into a dissertation. But, if compared with a master’s thesis, most aspects are longer and more rigorous.

The word count requirements for theses can vary significantly, but doctoral dissertations often range 40,000–80,000 words or, per Harvard , 100–300 pages.

Differences between a thesis and a dissertation

As already touched on, the key differences are in where the two documents are used, length, and rigor. There are also regional differences.

A thesis typically demonstrates a master’s degree program student's grasp and presentation of a specific subject in their field of study. It normally involves a literature review, data analysis, and original research, but it is usually shorter and less comprehensive than a dissertation. The standards for rigor and novelty may also be lower.

A dissertation requires more extensive research, original contributions to the field, and a deeper exploration of the research topic. A dissertation is typically the output associated with a doctoral degree program.

The main differences in structure between a thesis and a dissertation are in the scope and complexity.

The word count requirement for theses and dissertations can vary depending on the institution and program.

A thesis is usually 20,000–40,000 words. However, there have been cases of mathematics dissertations that were only a few pages long!

Doctoral dissertations may range 60,000 to upward of 100,000 words, and exceed 100 pages. Many universities, however, seek around 80,000 words.

Oversight and process

A thesis may simply be submitted to the student's instructor, though rigorous thesis programs require a committee and defense. A dissertation will nearly always require the student to choose a chair, a committee, and then go through a more rigorous defense and revision (if necessary).

• Committee: Master's thesis committees usually have fewer members (typically 2–3) than doctoral dissertation committees (often 4–5, or even more).
• Guidance: Master's students often receive more detailed direction from advisers than doctoral students, who are expected to work more independently.
• Review: Dissertation reviews are typically more rigorous, often involving external reviewers, while thesis reviews are usually internal.
• Defense: A dissertation defense is generally more intense and formal, as it often involves a presentation to the wider academic community, while a thesis defense might be more confined and informal.
• Revision: The revision process for a doctoral dissertation is typically more extensive, given the larger scope of the project and higher stakes involved, compared with those for a master's thesis.

Regional differences

The terms' use varies among (and even within) countries. Here are some general regional differences:

In the United Kingdom, a thesis is commonly associated with both master's and doctoral degree programs. For example, the University College London  refers to a thesis for EngD, MPhil, MD(Res), and PhD degrees. At the University of Nottingham , a dissertation is written for a research master’s degree.

In Australia and New Zealand , “thesis” is generally used to refer to a substantial research project completed for a higher degree, though not limited to a master’s (you’ll find ample references to a “PhD thesis”).

In Latin American countries,  the thesis is commonly used to refer to both master's and doctoral research projects.

Closing thoughts

Both theses and dissertations are necessary documents for students in graduate programs. Despite the differences in expectations, and even in definitions of these papers, the student-author must do a diligent and rigorous job to earn their degree.

What is the Difference Between a Dissertation and a Thesis?

And to make it even more confusing, some institutions or departments will even use the terms differently!

But what are we all really talking about when we refer to a dissertation or a thesis? And does the term you use actually impact on what you actually end up writing?

This article covers the main differences between a dissertation and thesis, and how the terms may differ depending on the course, university and location.

What is a dissertation?

A dissertation is a piece of academic writing centred around original research. In their dissertations, students review existing research but also build on this with unique hypotheses and approaches.

A dissertation can be used to disprove a previous theory or take existing theories and research in a new direction. It is a large research project that is usually completed at the end of the academic year.

Usually, a dissertation starts with a dissertation proposal , which is approved by a study supervisor. The student then completes the research and writes up the methodology , findings, evaluations and conclusions from the research.

Dissertations can be undertaken by both undergraduate and postgraduate students. At undergraduate level the word count is around 5,000 to 8,000 and at postgraduate level it is usually 10,000 to 15,000.

What is a thesis?

A thesis is an academic paper covering an in-depth review of existing research in a particular discipline. It will involve an academic argument, although it doesn’t usually require original research from the student. The existing research is used to support and evaluate the proposed argument.

A thesis is not usually required at undergraduate level and is more common at postgraduate level.

This large piece of written-up research is usually completed at the end of a masters degree. Some masters courses require a thesis to graduate.

Differences between a dissertation vs thesis

The main purpose of a writing a dissertation is to add new findings to the existing literature in that field with original research. Whereas theses tend to evaluate existing findings, as their purpose is to demonstrate knowledge and skills within the course’s subject matter.

In terms of how long it takes to complete a thesis or dissertation project, a thesis is typically shorter than a dissertation since there are fewer original research aspects involved. This means that it will probably take less time. However, this can differ depending on the university and the course.

Dissertations sometimes require an oral presentation, known as a viva , where findings are showcased to academics who ask questions about the research. Theses usually do not require this.

The root of the words 

The word ‘dissertation’ originates from the Latin word ‘dissertare’, meaning to continue to discuss and the Latin word ‘disserere’ which means to examine and discuss .

The word ‘thesis’ originally comes from the Greek word ‘tithenai’, which means to place or position. This later evolved into the Latin ‘thesis’, which had two meanings: an abstract question and to put something forward .

Similarities between a dissertation vs thesis

Although there are some key differences between a dissertation and a thesis, there are also similarities.

• Both are generally long pieces of academic writing, much longer than a typical essay.
• Both explore a topic in depth, whether you are conducting totally unique research or structuring an argument based on existing research.
• Both are considered a final project and usually required to graduate from a degree, masters or PhD. Students can graduate without a thesis or dissertation if they choose to complete a postgraduate diploma or postgraduate certificate instead.
• Excellent academic writing skills are highly important for both types of research project.

Is a dissertation harder than a thesis?

Though, the difficulty of a thesis or dissertation depends on your personal skill set. For instance, students that learn better by developing their own research ideas may find a dissertation easier than a thesis.

Difficulty can also depend on the level of the course. For instance, a thesis completed at doctorate level is likely to require more advanced knowledge than a thesis at undergraduate level.

The difficulty of either type of research project can also vary depending on the subject matter and the resources available to you.

Both dissertations and theses can be challenging, but don’t be put off by the thought of having to produce a larger body of work. Your supervisor will be there to support you.

Definitions depend on where you are

The terms ‘dissertation’ and ‘thesis’ are sometimes used interchangeably, and the meanings can differ depending on the country and university.

There are plenty of differences between the variant forms of English, such as British English and American English. Around the world, different English-speaking countries use the words ‘dissertation’ and ‘thesis’ differently. 

Generally, nations with British-based academic systems of university education use dissertation to refer to the body of work at the end of an undergraduate or masters level degree . British-based institutions generally use thesis to refer to the body of work produced at the end of a PhD . 

In countries and institutions that are based on the American system of education, the words tend to be used in reverse. However, institutions and even different departments in the same university can use the words differently. 

If you're in doubt, then stick with the way the university and department you're currently attending use the terms. 

Definitions can depend on the subject

In the UK, the terms ‘dissertation’ and ‘thesis’ are generally applied equally across institutions and subjects. 

However, in the US the meanings can differ between different subject areas. The term ‘thesis’ can be used to describe a piece of original research in US academia, whereas original research is usually referred to as a dissertation in the UK. 

If you’re studying in the US , you may complete a thesis at masters level in another subject area that involves wide-ranging reading and understanding rather than original research and still call it a thesis.

With so much interchangeability between the two terms, it’s understandable that there is often confusion in the debate between a dissertation vs thesis, as there is no clear answer. 

Always read specific course details to understand exactly what’s involved in the research project that you are required to produce.

Examples from US and UK universities

Georgetown University in the US refers to a dissertation and a thesis as both adding to your 'field of knowledge' . The University of Edinburgh recommends that you refer to your individual course handbook for guides to dissertations, so each department will have their own guidelines to using the word dissertation and thesis. At University College London they refer to a thesis as the piece of work at the end of an EngD, MPhil, MD(Res) or PhD, which are all research degrees. 

In conclusion

Ultimately, it doesn't really matter which word you use as both refer to a serious and lengthy piece of work where you can show what you have researched and understood as part of your postgraduate studies.

As long as you are referring to the piece of work that you are compiling in the same way as those in your department then you will avoid confusion.

It is important to check whether the research piece involves original research or expects you to build upon existing research.

Writing a dissertation or a thesis requires a substantial amount of planning and work and you don't want to let yourself down at the last hurdle with poor presentation of your work, so always keep an eye on your course or department guidelines.

What is a dissertation vs. a thesis?

In American English, a dissertation is a research paper that’s required to earn a doctorate degree, while a thesis is a research paper required to earn a master’s degree. Dissertations and theses (the plural of thesis ) are often mixed up because they’re both lengthy research papers written for higher education, especially as part of a master’s or doctorate program. A thesis or dissertation is often a requirement for obtaining an academic degree, and both are usually seen as a gatekeeper for becoming eligible to graduate.

Informally the words dissertation and thesis are often used interchangeably, which only adds to the confusion. However, in the formal academic world, their meanings are different, although some universities occasionally have their own unique definitions. Let’s take a look at what dissertation and thesis actually mean.

What is a dissertation?

In American English, a dissertation is a highly involved research paper written as a requirement to earn a doctorate degree. When we say “highly involved,” we mean it; dissertations run 300 pages or more, essentially becoming a book-length research paper.

The central attribute of a dissertation is original research: To earn a doctorate, a person must submit new discoveries and data to their chosen field. This is symbolic of becoming part of a body of academic knowledge, and a systemic way to encourage the advancement of science.

In scientific fields of study, dissertations are empirical , drawing on data collected by the writer. In less-scientific fields, like literature or philosophy, dissertations are nonempirical : Instead of new data, “original research” is replaced by innovative new ideas, interpretations, analyses, or perspectives.

Dissertation may also involve what’s known as a dissertation defense , an oral presentation in front of a panel of experts, in addition to the paper. In a dissertation defense, the experts ask questions about the findings to test their validity, and the student must “defend” their research by explaining their methods and reasoning. The panel then decides whether or not the student graduates and earns their degree.

What is a thesis?

In American English, a thesis paper is a lengthy research paper written as a requirement to earn a master’s degree (or sometimes a bachelor’s degree, depending on the university). Also referred to as a “senior thesis” for undergraduate courses, these papers are written at the end of a program as a culmination of their studies, similar to dissertations.

Unlike a dissertation, a thesis doesn’t necessarily involve original research or ideas, although many master’s theses do. Generally, a thesis is less about adding to a body of knowledge, and more about testing a student’s skills in research, comprehension, or analysis. Regardless, a thesis paper is still a considerable amount of work and requires more effort than a standard academic paper.

Dissertation vs. thesis in American and British English

We’ve talked before about how British English and American English are different , and the definitions of dissertation versus thesis are just another example.

In short, the meanings are reversed: In British English, the term dissertation is used for bachelor’s and master’s programs, whereas thesis is used for doctorates. Keep in mind that academic institutions are very different in the US and the UK, not to mention in each individual English-speaking country, so what’s involved in a bachelor’s, master’s, and doctorate program is also different.

Do you need to write a thesis or dissertation?

It’s important to remember that the words dissertation and thesis are frequently used interchangeably, so the technical definitions are just for formal situations—like when submitting one or the other. If you’re confused, you can also ask your adviser. Each school or institution may have their own definitions of the terms.
