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.
What is a “thesis statement” anyway?
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.

Writing Tips: Thesis Statements
Defining the Thesis Statement
What is a thesis statement?
Every paper you write should have a main point, a main idea, or central message. The argument(s) you make in your paper should reflect this main idea. The sentence that captures your position on this main idea is what we call a thesis statement.
How long does it need to be?
A thesis statement focuses your ideas into one or two sentences. It should present the topic of your paper and also make a comment about your position in relation to the topic. Your thesis statement should tell your reader what the paper is about and also help guide your writing and keep your argument focused.
Questions to Ask When Formulating Your Thesis
Where is your thesis statement?
You should provide a thesis early in your essay -- in the introduction, or in longer essays in the second paragraph -- in order to establish your position and give your reader a sense of direction.
Tip: In order to write a successful thesis statement:
- Avoid burying a great thesis statement in the middle of a paragraph or late in the paper.
- Be as clear and as specific as possible; avoid vague words.
- Indicate the point of your paper but avoid sentence structures like, “The point of my paper is…”
Is your thesis statement specific?
Your thesis statement should be as clear and specific as possible. Normally you will continue to refine your thesis as you revise your argument(s), so your thesis will evolve and gain definition as you obtain a better sense of where your argument is taking you.
Tip: Check your thesis:
- Are there two large statements connected loosely by a coordinating conjunction (i.e. "and," "but," "or," "for," "nor," "so," "yet")?
- Would a subordinating conjunction help (i.e. "through," "although," "because," "since") to signal a relationship between the two sentences?
- Or do the two statements imply a fuzzy unfocused thesis?
- If so, settle on one single focus and then proceed with further development.
Is your thesis statement too general?
Your thesis should be limited to what can be accomplished in the specified number of pages. Shape your topic so that you can get straight to the "meat" of it. Being specific in your paper will be much more successful than writing about general things that do not say much. Don't settle for three pages of just skimming the surface.
The opposite of a focused, narrow, crisp thesis is a broad, sprawling, superficial thesis. Compare this original thesis (too general) with three possible revisions (more focused, each presenting a different approach to the same topic):
- Original thesis:
- There are serious objections to today's horror movies.
- Revised theses:
- Because modern cinematic techniques have allowed filmmakers to get more graphic, horror flicks have desensitized young American viewers to violence.
- The pornographic violence in "bloodbath" slasher movies degrades both men and women.
- Today's slasher movies fail to deliver the emotional catharsis that 1930s horror films did.
Is your thesis statement clear?
Your thesis statement is no exception to your writing: it needs to be as clear as possible. By being as clear as possible in your thesis statement, you will make sure that your reader understands exactly what you mean.
Tip: In order to be as clear as possible in your writing:
- Unless you're writing a technical report, avoid technical language. Always avoid jargon, unless you are confident your audience will be familiar with it.
- Avoid vague words such as "interesting,” "negative," "exciting,” "unusual," and "difficult."
- Avoid abstract words such as "society," “values,” or “culture.”
These words tell the reader next to nothing if you do not carefully explain what you mean by them. Never assume that the meaning of a sentence is obvious. Check to see if you need to define your terms (”socialism," "conventional," "commercialism," "society"), and then decide on the most appropriate place to do so. Do not assume, for example, that you have the same understanding of what “society” means as your reader. To avoid misunderstandings, be as specific as possible.
Compare the original thesis (not specific and clear enough) with the revised version (much more specific and clear):
- Original thesis: Although the timber wolf is a timid and gentle animal, it is being systematically exterminated. [if it's so timid and gentle -- why is it being exterminated?]
- Revised thesis: Although the timber wolf is actually a timid and gentle animal, it is being systematically exterminated because people wrongfully believe it to be a fierce and cold-blooded killer.
Does your thesis include a comment about your position on the issue at hand?
The thesis statement should do more than merely announce the topic; it must reveal what position you will take in relation to that topic, how you plan to analyze/evaluate the subject or the issue. In short, instead of merely stating a general fact or resorting to a simplistic pro/con statement, you must decide what it is you have to say.
- Avoid merely announcing the topic; your original and specific "angle" should be clear. In this way you will tell your reader why your take on the issue matters.
- Original thesis: In this paper, I will discuss the relationship between fairy tales and early childhood.
- Revised thesis: Not just empty stories for kids, fairy tales shed light on the psychology of young children.
- Avoid making universal or pro/con judgments that oversimplify complex issues.
- Original thesis: We must save the whales.
- Revised thesis: Because our planet's health may depend upon biological diversity, we should save the whales.
- When you make a (subjective) judgment call, specify and justify your reasoning. “Just because” is not a good reason for an argument.
- Original thesis: Socialism is the best form of government for Kenya.
- Revised thesis: If the government takes over industry in Kenya, the industry will become more efficient.
- Avoid merely reporting a fact. Say more than what is already proven fact. Go further with your ideas. Otherwise… why would your point matter?
- Original thesis: Hoover's administration was rocked by scandal.
- Revised thesis: The many scandals of Hoover's administration revealed basic problems with the Republican Party's nominating process.
Do not expect to come up with a fully formulated thesis statement before you have finished writing the paper. The thesis will inevitably change as you revise and develop your ideas—and that is ok! Start with a tentative thesis and revise as your paper develops.
Is your thesis statement original?
Avoid, avoid, avoid generic arguments and formula statements. They work well to get a rough draft started, but will easily bore a reader. Keep revising until the thesis reflects your real ideas.
Tip: The point you make in the paper should matter:
- Be prepared to answer “So what?” about your thesis statement.
- Be prepared to explain why the point you are making is worthy of a paper. Why should the reader read it?
Compare the following:
- Original thesis:
- There are advantages and disadvantages to using statistics. (a fill-in-the-blank formula)
- Revised theses:
- Careful manipulation of data allows a researcher to use statistics to support any claim she desires.
- In order to ensure accurate reporting, journalists must understand the real significance of the statistics they report.
- Because advertisers consciously and unconsciously manipulate data, every consumer should learn how to evaluate statistical claims.
Avoid formula and generic words. Search for concrete subjects and active verbs, revising as many "to be" verbs as possible. A few suggestions below show how specific word choice sharpens and clarifies your meaning.
- Original: “Society is...” [who is this "society" and what exactly is it doing?]
- Revised: "Men and women will learn how to...," "writers can generate...," "television addicts may chip away at...," "American educators must decide...," "taxpayers and legislators alike can help fix..."
- Original: "the media"
- Revised: "the new breed of television reporters," "advertisers," "hard-hitting print journalists," "horror flicks," "TV movies of the week," "sitcoms," "national public radio," "Top 40 bop-til-you-drop..."
- Original: "is, are, was, to be" or "to do, to make"
- Revised: any great action verb you can concoct: "to generate," "to demolish," "to batter," "to revolt," "to discover," "to flip," "to signify," "to endure..."
Use your own words in thesis statements; avoid quoting. Crafting an original, insightful, and memorable thesis makes a distinct impression on a reader. You will lose credibility as a writer if you become only a mouthpiece or a copyist; you will gain credibility by grabbing the reader with your own ideas and words.
A well-crafted thesis statement reflects well-crafted ideas. It signals a writer who has intelligence, commitment, and enthusiasm.
