80 TED Talk Topics You Can Actually Finish (2026)

A good TED talk topic is one idea you can state as a claim, prove with something you lived or built, and finish in 18 minutes or less. "Innovation" is a theme. "We banned phones on one production line and made fewer mistakes" is a talk.

This page lists 190 TED talk topics: the 80 core ideas on work, science, cities and culture, plus 110 more for students, teachers, personal stories, motivational and funny talks, and 5-minute slots. They are original TED-style ideas, not titles copied from TED.com.

After the lists, you get 4 steps to choose one and a 12-minute outline. Tap Create next to a topic to start a deck on it in GenPPT.

The TED-shaped idea

A TED-shaped idea is one sentence the audience can repeat on the way home. Chris Anderson's book TED Talks: The Official TED Guide to Public Speaking calls this the through-line. It is a claim, not a topic cluster.

Use this filter before you commit:

• I have a scar or a build, not only an opinion
• I can show one object, photo, or demo
• A smart skeptic has a fair objection I will answer

Most weak topics are themes. Narrow the theme until it has a verb and a point of view.

If you need two sides, use debate topics. If you need to teach a process, use informative speech topics.

TED talk topics for students

Good TED talk topics for students come from the school day: a class, a job, a team, a bus ride, a family rule. You do not need a big life story. You need one small true event and what it changed.

For a class assignment, plan 5 to 8 minutes unless your teacher sets a length.

How to choose a TED talk topic

Choose in 4 steps. Do them before you write a word of the script, so you do not start a talk you cannot finish.

1. List what you have done, not what you have read. Write down 10 things you built, fixed, failed at, measured or lived through. A topic from this list comes with a scene. A topic from an article does not.

2. Write the through-line. Fill in this template for your best three items:

Most people think ____.
I learned ____ when ____.
So we should ____.

3. Run the five tests. Drop any idea that fails two or more.

The New and Skeptic tests follow the questions that TED gives TEDx organizers for speaker preparation: what misconception would you clear up, why does the idea matter and to whom, and who would disagree.

4. Say it out loud to one person. Time it. If you cannot explain the idea in 60 seconds without slides, the topic is still a theme, so narrow it again.

Then match the topic to the occasion:

What real TED talks are about

Look at the titles on TED's playlist of its most popular talks. None of them is a theme. Each one is a question or a claim.

Lengths are the ones TED lists on that playlist. They run from about 8 minutes to about 19, so a short talk is not a lesser talk.

To see every subject TED covers, browse TED's topic index from A to Z. Use it to find the theme. Then narrow the theme to a claim with the steps above.

12-minute shape

Twelve minutes is a good default. It sits under the 18-minute ceiling that TEDx rules set for most talks, and it leaves no room for a second idea.

The first minute decides if the room stays with you. For first lines you can adapt, see presentation hook examples.

Slides for a TED-style talk

Slides: title, one photo, one diagram, one number, close. If you need speaker notes on-screen, it is not a TED-style talk.

Put notes in presenter view. See PowerPoint speaker notes.

TED's slide guidance for TEDx speakers says the same thing in more detail:

• Slides are optional. Many of the best TED and TEDx talks have none.
• Remove slides that are a headline plus bullet points.
• Let each slide support one point only.
• Keep text short. One or two lines is enough most of the time.
• Make text large enough to read from the back of the room.

Other talk lengths

Write the full script, then cut 20%. The word counts below assume 130 words per minute. Time yourself for one minute to find your own rate.

For a 10-minute class or work slot with a slide-by-slide grid, see 10-minute presentation topics.

Worked through-line: a shop floor without phones

This is an invented example that shows the shape. The 400 days and the 18% are placeholders, not real data. Replace them with numbers you measured.

Claim. When we banned phones on one production line for 400 days, defects fell 18%. Attention was the process control we had been missing.

Slides. Title, photo of the box, one chart, the exception, close.

Notice what the outline leaves out: the company history, the speaker's resume and a list of five lessons. One claim, one number, one exception, one action.

Student TED-style (claim-shaped)

These 10 student topics are already sharpened into claims. Each one names what happened and what changed.

They are shapes to copy, not facts to repeat. Say "attendance doubled" only if you counted it.

• I stopped counting participation points. Quiet students started writing betterCreate
• The cafeteria tray taught me more about waste than the climate unitCreate
• We translated parent-teacher night. Attendance doubledCreate
• My "learning style" was an excuse. Retrieval practice was the methodCreate
• The club nobody joined was a bus-schedule problemCreate
• I read the last page first. Here is what that costsCreate
• Group projects punish the writer unless you grade the partsCreate
• Captions in class helped the kids who would never askCreate
• The field trip form is the real civics lessonCreate
• I memorized a poem. It was a better focus drill than an appCreate

Turn your topic into slides

A TED-style talk needs few slides, so most of the work is the script. When the script is done, GenPPT can make the slides:

1. Type your through-line, or upload your script as a PDF, a Word document or a text file.
2. GenPPT researches the topic and drafts an outline. You approve it before any slide is designed.
3. Pick a visual concept. GenPPT generates full-slide designed slides in about 2 to 3 minutes.
4. Edit slides in chat. For a TED-style talk, ask for less text on each slide.
5. Export to PowerPoint (.pptx) or PDF. The .pptx file opens in PowerPoint, Google Slides and Keynote.

Know the limits. Slides are image-native designs, so charts do not link to Excel. Check every number and claim yourself before you say it on stage.

There is no free plan. The trial costs $1 for 3 days of full access, and it requires a card. After that, GenPPT costs $25 per month or $99 per year, with 20 decks per month and watermark-free .pptx and PDF export.

FAQ

What is a good topic for a TED talk?

A good TED talk topic is one claim you can say in one sentence and support with your own experience or work. It is new to the audience, and a fair skeptic could disagree with it. "Why shade is a public good" is a topic. "Climate change" is a theme.

How long is a TED talk?

TED's TEDx rules say talks are typically under 18 minutes, and that 3 to 9 minutes is ideal for one focused idea. Some of TED's most popular talks run slightly longer than 18 minutes. For a class or a team event, 5 to 12 minutes is enough.

What are good TED talk topics for students?

Good student topics come from daily school life: a grade, a part-time job, a group project, a move to a new school. Pick one event and say what it changed in how you think or act. Start with the student lists on this page.

What is the difference between a TED talk and a class speech?

A class speech can explain a process or argue a side. See informative speech topics for those. A TED-style talk needs a turn: the moment where you, and then the audience, stop believing the common story.

Can a TED talk be a personal story?

Yes, if the last three minutes are useful to strangers. Tell the story to carry the idea, not to describe your life. If the audience cannot use the ending, it is a memoir, not a talk.

Do you need slides for a TED talk?

No. TED's guidance for TEDx speakers says slides are optional. If you use them, plan 5 to 8 slides for 12 minutes, with one image or one number on each and no bullet walls.

How do you get to speak at TED or TEDx?

TED takes speaker nominations all year, and you can nominate yourself. TEDx events are organized locally, so you contact the organizer of that event. TEDx rules do not allow talks that promote the speaker's own product or business, or that push an inflammatory political or religious agenda.

The topics on this page are TED-style ideas. Using one does not get you onto a TED stage.

Your next step is the first line. Use these presentation hook examples.
