What this calculator does
Speaking is far slower than reading, which is why a script that looks short on the page can overrun a slot by ten minutes. This tool converts your word count into spoken duration at the pace you actually deliver, and lets you add the overhead that live talks always need.
If you give it your slot length, it also tells you how much to cut — in words, not just in minutes.
How to use it
- Paste your script, including everything you intend to say out loud.
- Choose the pace that matches your delivery. Most presenters land between 130 and 160 words per minute.
- Add a pause allowance if the talk is live: 10 percent for a straightforward presentation, 20 percent or more if there are demos, slide transitions or laughs.
- Enter your slot length to see the gap and, if you are over, roughly how many words to cut.
- Rehearse once against a timer and adjust the custom rate to your real pace — that makes every future estimate accurate.
How speaking time is estimated
The base calculation is word count ÷ words per minute, then the pause allowance is added as a percentage on top. The four presets come from commonly cited delivery rates:
- 100 wpm — deliberate delivery: ceremonial speeches, difficult material, or an audience listening in a second language.
- 130 wpm — conversational: podcasts, interviews, relaxed webinars.
- 150 wpm — average presenting pace, and a reasonable default for a rehearsed talk.
- 180 wpm — fast: energetic conference talks, advertising reads, and most people when nervous.
Audiobook narration is usually recorded between 150 and 160 words per minute, and broadcast news reads faster, often near 180. Voiceover for explainer video tends to sit at 140 to 160 so viewers can follow visuals at the same time.
The estimate covers the words only. It does not know about the silence you leave after a key point, the thirty seconds spent finding the right slide, or the question that arrives mid-demo. That is exactly what the pause allowance is for, and it is why rehearsing remains the only real measurement.
Examples
Conference talk. An 18-minute slot at 150 wpm holds about 2,700 words — but with a 15 percent pause allowance the practical target is closer to 2,350. Scripts written to the raw number are the reason so many talks get cut off.
Wedding speech. Five minutes at a deliberate 110 wpm is roughly 550 words. That is about one page and a half, double spaced.
YouTube narration. A 10-minute video at 150 wpm needs around 1,500 words of script, minus whatever time the visuals carry alone.
Elevator pitch. Thirty seconds at a conversational 130 wpm is 65 words. If your pitch is 150 words, it is a two-minute pitch wearing a costume.
Who this is for
- Conference and meetup speakers fitting a talk into a fixed slot with time for questions.
- Video creators matching narration length to a target runtime.
- Podcasters planning segment lengths before recording.
- Teachers and trainers pacing a lesson so the last section is not rushed.
- Voice actors quoting on a script by duration rather than word count.
- Anyone giving a toast who would like to sit down before the room does.

Frequently asked questions
How many words is a five-minute speech?
At an average presenting pace of 150 words per minute, about 750 words. At a slower, more deliberate 110 words per minute it is about 550. Add a pause allowance and aim slightly under either figure.
What is a normal speaking rate?
Conversational English runs roughly 120 to 150 words per minute. Prepared presentations tend to be a little slower and more even. Radio and advertising reads run faster, often 180 or more.
Should I include pauses in the estimate?
For a live talk, yes. Use 10 percent for a straightforward reading, 15 to 20 percent for a presentation with slides, and more if you expect audience interaction. For recorded narration that will be edited, 0 to 5 percent is usually enough.
Why is my rehearsal slower than the estimate?
Almost everyone slows down when they add emphasis, breathe properly and look at the audience. That is a feature, not a fault. Time one rehearsal, divide your word count by the minutes it took, and use that number as your custom rate from then on.
Does it work for languages other than English?
The arithmetic works for any language, but the word-based presets do not. Languages differ in how much meaning a word carries and how fast it is spoken. For a non-English script, time yourself on a sample and enter your measured rate as a custom value.
