Table of Contents

A thesis statement is a concise summary of the main point or claim of an essay, research paper, or other piece of academic writing.

It presents the topic of your paper and your position on the topic, ideally in a single sentence.

Think of it as the roadmap to your paper—it guides your readers through your arguments and provides a clear direction.

Key Elements of a Thesis Statement

Clarity: Your thesis should be clear and specific.
Position: It should convey your stance on the topic.
Argument: The statement should make a claim that others might dispute.

Types of Thesis Statements

There are various types of thesis statements depending on the kind of paper you’re writing.

Here are the main ones:

Standard Method – This is the classic thesis statement used in many academic essays. It provides a straightforward approach, clearly stating the main argument or claim and outlining the supporting points.
Research Paper – Designed for research papers, this type involves extensive research and evidence. It presents a hypothesis or a central argument based on your research findings.
Informative Essay – Used for essays that aim to inform or explain a topic. It provides a clear summary of what the reader will learn.
Persuasive Essay – For essays meant to persuade or convince the reader of a particular point of view. It clearly states your position and outlines your main arguments.
Compare and Contrast Essay – Used when comparing two or more subjects. It highlights the similarities and differences between the subjects and presents a clear argument based on these comparisons.
Analytical Essay – Breaks down an issue or idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
Argumentative Essay – Makes a claim about a topic and justifies this claim with specific evidence. It’s similar to the persuasive essay but usually requires more evidence and a more formal tone.
Expository Essay – Explains or describes a topic in a straightforward, logical manner. It provides a balanced analysis of a subject based on facts without opinions.
Narrative Essay – Tells a story or relates an event. The thesis statement for a narrative essay usually highlights the main point or lesson of the story.
Cause and Effect Essay – Explores the causes of a particular event or situation and its effects. It provides a clear argument about the cause and effect relationship.

Thesis Statement Tips

Writing a strong thesis statement is crucial for a successful essay. Here are some tips to help you craft a killer thesis statement:

Be Specific: Avoid vague language. Make sure your thesis statement clearly defines your argument or main point.
Be Concise: Keep it to one or two sentences. Your thesis statement should be brief and to the point.
Make It Arguable: Ensure that your thesis statement presents a claim or argument that can be disputed.
Place It Appropriately: Typically, your thesis statement should be placed at the end of your introduction paragraph.
Revise and Refine: Don’t be afraid to revise your thesis statement as you write and refine your essay. It should evolve as your ideas develop.

Common Thesis Statement Errors

Avoid these common errors when crafting your thesis statement:

Too Broad: A thesis statement that is too broad makes it difficult to focus your essay. Narrow it down to a specific point.
Too Vague: Avoid vague language that lacks specificity. Be clear about what you’re arguing.
Lacks an Argument: Ensure that your thesis statement makes a clear argument or claim. Avoid statements that are purely factual or descriptive.
Too Complex: A thesis statement should be straightforward and easy to understand. Avoid overly complex sentences.
Off-Topic: Make sure your thesis statement is directly related to the topic of your essay. Stay on track.

How Do You Start a Thesis Statement?

Starting a thesis statement involves using clear and concise language that sets the stage for your argument.

Here are some exact words and phrases to begin with:

“The purpose of this paper is to…”
“This essay will argue that…”
“In this essay, I will demonstrate that…”
“The central idea of this paper is…”
“This research aims to prove that…”
“This study focuses on…”
“This analysis will show that…”
“The main argument presented in this paper is…”
“The goal of this essay is to…”

How Long Should a Thesis Statement Be?

A thesis statement should be clear and concise, typically one to two sentences long.

Aim for 20 to 30 words, ensuring it includes the main topic, your position, and the key points that will be covered in your paper.

This provides a focused and precise summary of your argument, making it easier for readers to understand the main direction of your essay or research paper.

While brevity is essential, it’s also crucial to provide enough detail to convey the scope of your argument.

Avoid overly complex sentences that can confuse readers. Instead, strive for a balance between clarity and comprehensiveness, ensuring your thesis statement is straightforward and informative.

How to Write a Strong Thesis Statement

A thesis can be found in many places—a debate speech, a lawyer’s closing argument, even an advertisement. But the most common place for a thesis statement (and probably why you’re reading this article) is in an essay.

Whether you’re writing an argumentative paper, an informative essay, or a compare/contrast statement, you need a thesis. Without a thesis, your argument falls flat and your information is unfocused. Since a thesis is so important, it’s probably a good idea to look at some tips on how to put together a strong one.

Guide Overview

What is a “thesis statement” anyway.

The qualities of a solid thesis statement (video)

You may have heard of something called a “thesis.” It’s what seniors commonly refer to as their final paper before graduation. That’s not what we’re talking about here. That type of thesis is a long, well-written paper that takes years to piece together.

Instead, we’re talking about a single sentence that ties together the main idea of any argument . In the context of student essays, it’s a statement that summarizes your topic and declares your position on it. This sentence can tell a reader whether your essay is something they want to read.

2 Categories of Thesis Statements: Informative and Persuasive

Just as there are different types of essays, there are different types of thesis statements. The thesis should match the essay.

For example, with an informative essay, you should compose an informative thesis (rather than argumentative). You want to declare your intentions in this essay and guide the reader to the conclusion that you reach.

To make a peanut butter and jelly sandwich, you must procure the ingredients, find a knife, and spread the condiments.

This thesis showed the reader the topic (a type of sandwich) and the direction the essay will take (describing how the sandwich is made).

Most other types of essays, whether compare/contrast, argumentative, or narrative, have thesis statements that take a position and argue it. In other words, unless your purpose is simply to inform, your thesis is considered persuasive. A persuasive thesis usually contains an opinion and the reason why your opinion is true.

Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.

In this persuasive thesis statement, you see that I state my opinion (the best type of sandwich), which means I have chosen a stance. Next, I explain that my opinion is correct with several key reasons. This persuasive type of thesis can be used in any essay that contains the writer’s opinion, including, as I mentioned above, compare/contrast essays, narrative essays, and so on.

2 Styles of Thesis Statements

Just as there are two different types of thesis statements (informative and persuasive), there are two basic styles you can use.

The first style uses a list of two or more points . This style of thesis is perfect for a brief essay that contains only two or three body paragraphs. This basic five-paragraph essay is typical of middle and high school assignments.

C.S. Lewis’s Chronicles of Narnia series is one of the richest works of the 20th century because it offers an escape from reality, teaches readers to have faith even when they don’t understand, and contains a host of vibrant characters.

In the above persuasive thesis, you can see my opinion about Narnia followed by three clear reasons. This thesis is perfect for setting up a tidy five-paragraph essay.

In college, five paragraph essays become few and far between as essay length gets longer. Can you imagine having only five paragraphs in a six-page paper? For a longer essay, you need a thesis statement that is more versatile. Instead of listing two or three distinct points, a thesis can list one overarching point that all body paragraphs tie into.

Good vs. evil is the main theme of Lewis’s Narnia series, as is made clear through the struggles the main characters face in each book.

In this thesis, I have made a claim about the theme in Narnia followed by my reasoning. The broader scope of this thesis allows me to write about each of the series’ seven novels. I am no longer limited in how many body paragraphs I can logically use.

Formula for a Strong Argumentative Thesis

One thing I find that is helpful for students is having a clear template. While students rarely end up with a thesis that follows this exact wording, the following template creates a good starting point:

_____ is true because of _, _, and _____.

Conversely, the formula for a thesis with only one point might follow this template:

_ is true because of ___.

Students usually end up using different terminology than simply “because,” but having a template is always helpful to get the creative juices flowing.

The Qualities of a Solid Thesis Statement

When composing a thesis, you must consider not only the format, but other qualities like length, position in the essay, and how strong the argument is.

Length: A thesis statement can be short or long, depending on how many points it mentions. Typically, however, it is only one concise sentence. It does contain at least two clauses, usually an independent clause (the opinion) and a dependent clause (the reasons). You probably should aim for a single sentence that is at least two lines, or about 30 to 40 words long.

Position: A thesis statement always belongs at the beginning of an essay. This is because it is a sentence that tells the reader what the writer is going to discuss. Teachers will have different preferences for the precise location of the thesis, but a good rule of thumb is in the introduction paragraph, within the last two or three sentences.

Strength: Finally, for a persuasive thesis to be strong, it needs to be arguable. This means that the statement is not obvious, and it is not something that everyone agrees is true.

Example of weak thesis:

Peanut butter and jelly sandwiches are easy to make because it just takes three ingredients.

Most people would agree that PB&J is one of the easiest sandwiches in the American lunch repertoire.

Example of a stronger thesis:

Peanut butter and jelly sandwiches are fun to eat because they always slide around.

This is more arguable because there are plenty of folks who might think a PB&J is messy or slimy rather than fun.

Composing a thesis statement does take a bit more thought than many other parts of an essay. However, because a thesis statement can contain an entire argument in just a few words, it is worth taking the extra time to compose this sentence. It can direct your research and your argument so that your essay is tight, focused, and makes readers think.
