The number
At 150 words per minute, a fifteen minute speech is 2,250 words. Two thousand words is the safer target, for a reason specific to this length: fifteen minute slots almost always include questions.
Check whether questions are inside the slot
This single question changes the answer by 500 words.
- 15 minutes plus questions: write 2,100 words.
- 15 minutes including questions: plan an 11 minute talk — about 1,650 words — and leave four minutes for the room.
Conference programmes are often ambiguous about which they mean. Ask the organiser. Speakers who assume the generous reading and are wrong get cut off in the middle of their conclusion, which is the worst place to be stopped.
Structure at this length
Fifteen minutes is the first length where you can develop an argument properly rather than assert three points. That means a shape rather than a list:
| Section | Words | Time |
|---|---|---|
| Hook — a specific problem or moment | 200 | 1:20 |
| The claim you are making | 150 | 1:00 |
| Why the obvious answer is wrong | 400 | 2:40 |
| Your answer, with evidence | 600 | 4:00 |
| An objection, answered honestly | 350 | 2:20 |
| What follows from it | 250 | 1:40 |
| Close | 150 | 1:00 |
That is 2,100 words, leaving 150 words of slack. The section worth protecting is the objection: at ten minutes there is no room for it, and its absence is what makes short talks feel like pitches.
Slides
Ten to fifteen slides is right. TED talks — which run at 18 minutes — typically use fewer than twenty, and many use almost none.
The trap at this length is the slide that contains your script. If a slide has forty words on it, the audience reads it in eight seconds and then waits for you to finish saying the same thing. Either the slide is the point or you are; it cannot be both.
Rehearse once, out loud, timed
At 2,250 words the difference between your reading pace and your delivery pace compounds. A rate 15 words per minute faster than you assumed finishes 90 seconds early; 15 slower overruns by the same. That is the difference between a clean finish and being cut off.
One timed run-through out loud, at the pace you will actually use, tells you more than any calculator. Then set the speaking time calculator to the rate you measured and the rest of the script will be accurate.
