From words to minutes on stage
Estimate how long your speech, presentation, or thesis defense will take — from a word count or a pasted script.
How many words do you need?
| Talk length | Slow (110 wpm) | Average (140 wpm) | Fast (170 wpm) |
|---|---|---|---|
| 3 min | 330 | 420 | 510 |
| 5 min | 550 | 700 | 850 |
| 10 min | 1,100 | 1,400 | 1,700 |
| 15 min | 1,650 | 2,100 | 2,550 |
| 20 min | 2,200 | 2,800 | 3,400 |
| 30 min | 3,300 | 4,200 | 5,100 |
| 45 min | 4,950 | 6,300 | 7,650 |
| 60 min | 6,600 | 8,400 | 10,200 |
Frequently asked questions
How many words is a 10-minute presentation?
About 1,400 words at an average pace of 140 words per minute — roughly 1,100 if you speak slowly, 1,700 if fast.
What pace should I plan for a thesis defense?
Plan around 130–140 words per minute. Nerves speed you up, while slides, pauses, and pointer time slow the effective pace — leave 10–15% headroom.
How accurate is the estimate?
It's a planning estimate. Rehearse with a timer at least once: pauses for slides, questions, and demos add time that raw word counts can't capture.
What's the difference between speaking and reading time?
Silent reading averages about 238 words per minute — much faster than speech. Use reading time for handouts and abstracts, speaking time for talks.
