How to Write a Thesis Statement (with Examples)
A thesis statement is the one sentence that tells the reader your main argument and how you will support it. Get it right and the rest of the essay almost writes itself.
The formula
A strong thesis = a specific claim + the main reasons. Template: "[Topic] is [your claim] because [reason 1], [reason 2], and [reason 3]."
Weak vs strong
Weak: "Social media is bad." (Too vague — no argument, no reasons.)
Strong: "Social media harms teenagers because it disrupts sleep, fuels comparison, and shortens attention spans." (Specific claim + three reasons that become your paragraphs.)
Quick checklist
Before you commit to a thesis, run it through this list.
- •Does it take a clear position someone could disagree with?
- •Is it specific, not a general topic?
- •Does it preview your main reasons?
- •Can you actually support it with evidence?
Frequently asked questions
Where does the thesis statement go?
Usually as the last sentence of your introduction, so the reader knows your argument before the body paragraphs.
Can a thesis be more than one sentence?
For most school essays, keep it to one clear sentence. Longer or research papers may use two.
