The short answer: about 650 words for five minutes at a comfortable speaking pace. The useful answer is that speaking rates vary far more than word-count guides suggest, and the difference decides whether you finish early or get cut off.
The table
Measured speaking rates for prepared talks cluster around 130 words per minute. Conversational delivery runs faster, and anything with data or unfamiliar names runs slower.
| Talk length | Slow (110 wpm) | Normal (130 wpm) | Fast (160 wpm) |
|---|---|---|---|
| 1 minute | 110 words | 130 words | 160 words |
| 3 minutes | 330 words | 390 words | 480 words |
| 5 minutes | 550 words | 650 words | 800 words |
| 10 minutes | 1,100 words | 1,300 words | 1,600 words |
| 20 minutes | 2,200 words | 2,600 words | 3,200 words |
A TED-style 18-minute talk is therefore roughly 2,300 words — which surprises people who have written 4,000.
Why the spread is so wide
Three things move your rate more than nerves do:
- Pauses. A talk with deliberate pauses after key points can lose 15% of its word budget, and it is almost always the better talk for it.
- Complexity. Numbers, names and technical terms need to be said slowly enough to land. A finance update is not delivered at the pace of a personal story.
- Audience. A second language in the room, a large hall, or a translated session all slow delivery down, and none of them show up in a word count.
Measure your own pace instead of guessing
This takes two minutes and beats any table:
- Pick a passage of your actual talk — not a random text, because your material is what sets your pace.
- Read it aloud at the speed you intend to present, and time yourself.
- Paste the passage into the word counter to get its word count.
- Divide the words by the minutes. That number is your rate, and it is the only one that matters for your script.
The counter also shows a speaking time estimate at 140 words per minute as you type, so you can watch a draft grow against its slot rather than discovering the overrun in rehearsal.
Writing to a time, not a length
Write the talk first and cut second. When you cut, take out whole points rather than trimming words from every sentence — a script cut evenly loses its rhythm and still overruns, because the pauses are what actually cost time.
A practical rule: aim for 90% of your budget. Five minutes of material for a five-minute slot leaves nothing for the laugh, the slide that will not advance, or the question you decide to answer. 585 words for a five-minute talk is a more realistic target than 650.
