How many words per minute should you speak in a presentation?

As a starting point for a presentation, aim for about 170 to 190 words per minute while you are actually speaking. That is the range where listeners recognized the most content in a controlled study of recorded news ¹. The same listeners rated that speed as normal and easy to understand ². The study used recordings of radio news, not live talks, so treat the range as a starting point and check it with your own audience.

Conversation sets the baseline, and the presentation slot runs slower

The overall rate in recorded telephone conversation is 196 words per minute, counting every pause ³. Once the silences are removed, the rate while people are actually talking is 236 words per minute ⁴. A presentation is not a chat, though. It has slides, questions and deliberate silences, so the overall rate across the whole slot will be lower than the rate you speak at.

That distinction matters when you plan. Set the 170 to 190 figure as the rate while you talk, and expect the slot to take longer than the words alone suggest. The speaking speed guide explains the two measures in more detail, and the articulation rate entry defines the spoken-only figure.

The best-supported range is for news, and no study fixes one number for presenters

The most useful measured evidence comes from a 2016 study by Emma Rodero, in which 200 students heard one-minute radio news items at different speeds ¹. The study shows where listeners follow best. It does not test a live speaker, and it does not test a talk with slides.

A comparison of TED talks and university lectures found that speech was significantly faster in TED talks, measured in syllables per second ⁵. That tells you how the two genres differ, not how fast a presenter should go. We found no large measured study that sets a single target for presenters, so the 170 to 190 range is the best available reference, not a rule.

A 2005 study of dictation gives normal speaking speed as 125 to 150 words per minute ⁶. That is a round figure in the abstract rather than a measured result, so it works as a lower reference, not a target.

Content density changes the right speed

Rodero's design varied how much information each clip carried, and the best results moved with it. Recognition was highest at 170 words per minute for high-density content and 190 for low-density content ¹. In practice, a talk packed with figures, names and dates belongs at the slower end of the range, and a talk built on stories and examples can sit near the top.

Turn the target into a script length

Multiply the time you have by your target to get the number of words you should speak. At 170 words per minute, a ten-minute talk holds about 1,700 words of speech ⁷. Write the script to that count, not to the length of the slide deck.

1. Set the slot, for example 10 minutes, and subtract any time for questions.
2. Multiply the minutes by 170 for the low end of the range, and by 190 for the high end.
3. Write the script to that count, then read it aloud with a timer.
4. Record the run and count the words in the transcript. The method in the speaking speed guide walks through the count.
5. If you finish early, add a pause where a slide should land rather than more words.

The last step is the one most speakers skip. A talk that pauses to let a slide register will run below its spoken rate, so plan the pauses into the time, not around it.

When to go slower or faster

Go toward 170 when the material is dense, with many figures, names or steps, because the study's best recognition at the slower end came with high-density content. Go toward 190 for lighter material. The study does not test large rooms or one-time listening, so for those cases, slowing down is a judgment call you should test with a rehearsal audience.
