Speaking Time Calculator
Calculate how long it takes to speak your text aloud for presentations and speeches.
Every speaking slot has a hard edge: the emcee waving from the side of the stage, the professor pointing at the clock. Writing a script that fits the slot means knowing your delivery speed, and most people have never measured theirs. The calculator defaults to 130 words per minute - a deliberate presentation pace audiences can follow without effort.
Word count divided by pace only gets you a first estimate, though. Pauses, slide changes and audience reactions all add time, which is why the timing advice further down leans toward writing short.
How Many Words Do You Need?
This is the question everyone asks. Here's a quick reference based on a comfortable presentation pace of 130 WPM:
- 3-minute speech: about 390 words
- 5-minute speech: about 650 words
- 7-minute speech: about 910 words
- 10-minute presentation: about 1,300 words
- 15-minute presentation: about 1,950 words
- 20-minute presentation: about 2,600 words
If you speak faster (around 150 WPM), bump those numbers up by about 15%. If you speak slower or your content is dense, aim a bit lower.
Speaking Speeds by Context
- Formal presentations and lectures: 120-150 WPM
- TED Talks: averaging about 163 WPM (faster than typical presentations)
- Conversational speech: 150-170 WPM
- Audiobook narration: 150-160 WPM
- Auctioneers: 250+ WPM
TED speakers tend to talk a bit faster than your average conference presenter. That's partly because they rehearse heavily and their content flows naturally. Don't try to match that speed unless you've practiced just as much.
Timing Tips That Actually Help
Always aim to finish under your time limit. Got a 10-minute slot? Write 8-9 minutes of content. That buffer is for pauses, audience reactions and the fact that you'll probably talk slower than you practiced.
Speaking of practice - do it out loud at least three times with a stopwatch. Reading silently is much faster than speaking, so a silent read-through tells you nothing about timing. Live delivery also tends to run slower than rehearsal: nerves, pauses for emphasis and audience reactions all stretch the clock. Treat your timed out-loud run as the minimum.
Find Your Personal Speaking Rate
Everyone speaks at a different speed. The best way to find yours is to read a 500-word passage out loud and time it. Divide 500 by however many minutes it took. That's your WPM. Plug that number into the calculator for the most accurate estimate.
How to Use
- Paste your speech or presentation script into the editor.
- Check the estimated speaking time that shows up below.
- Use the WPM slider to match your personal speaking speed.
- Add or cut content until you hit your target time.
Frequently Asked Questions
How many words is a 5-minute speech?
At a comfortable presentation pace of 130 WPM, that's about 650 words. If you speak faster at around 150 WPM, aim for about 750 words. When in doubt, go a bit short and leave room for pauses.
How many words for a 10-minute presentation?
About 1,300 words at 130 WPM. If you have visual slides, you might need fewer words since you'll pause to let people look at them. Factor in Q&A time too if that's part of your slot.
What's the average TED Talk speaking speed?
TED speakers average about 163 words per minute, which is faster than a typical conference presentation. They rehearse a lot and their talks are tightly scripted, which allows for the quicker pace.
Should I memorize my speech or use notes?
Most experts recommend using brief notes or bullet points rather than a full script. When people read from a script, they tend to sound robotic. Knowing your key points and speaking naturally gets better audience response.
Why is my actual speech longer than the estimate?
You're probably pausing more than you think. Natural pauses for emphasis, slide transitions and audience reactions add up, so live delivery usually runs slower than practice at home. Time a full out-loud dress run and treat that as your minimum.
Does talking faster make my presentation worse?
Usually, yes. Rushing makes you sound nervous and your audience can't absorb the information. Slowing down and pausing between key points actually makes you seem more confident and helps people remember what you said.
