Your words per minute is words divided by minutes: read a known word count aloud, time it, and divide. A 750-word script delivered in 5 minutes 12 seconds is 144 wpm (750 / 5.2 = 144). Typical rates run 110 to 180 wpm; knowing your own number makes every speech-length estimate exact instead of approximate.
Words per minute is exactly what it sounds like: the number of words you say divided by the number of minutes it takes. If you read a 750-word script aloud and it takes 5 minutes, your pace is 750 / 5 = 150 wpm. If it takes 5 minutes 12 seconds (5.2 minutes), your pace is 750 / 5.2 = 144 wpm.
That is the entire calculation, and it is the single most useful number a speaker can know. Every speech-length estimate in every guide on this site is words = minutes x wpm. Plug in your measured pace instead of the 150 average and the estimates stop being estimates.
You need a word count and a stopwatch. Your phone has both.
Count the words with any word counter, or paste the sample into the speech time calculator, which counts words as you type and shows the time at every pace from 110 to 180 wpm.
Example 1: the rehearsal check. Your script is 750 words. Rehearsal one runs 5 minutes 12 seconds. 750 / 5.2 = 144 wpm. Your 5 minute slot needs 5 x 144 = 720 words, so trim 30 words or accept finishing 12 seconds over.
Example 2: the fast talker. A 1,300-word conference script rehearses at 8 minutes 40 seconds (8.67 minutes). 1,300 / 8.67 = 150 wpm exactly. The 10 minute slot wants 1,500 words at this pace, so there is room to add a 200-word story, about 80 seconds.
Example 3: the slow, deliberate speaker. 300 words of a keynote opening takes 2 minutes 5 seconds (2.08 minutes). 300 / 2.08 = 144 wpm. Same number as example 1, different speaker: pace is personal, and the table below is a map, not a verdict.
| situation | typical wpm | notes |
|---|---|---|
| slow, deliberate keynote | 110-130 | heavy pauses, emphasis on each point |
| conversation | 130-150 | thinking pauses slow the average |
| rehearsed presentation | 150 | the standard planning number |
| audiobook narration | 150-160 | trained clarity at speed |
| energetic pitch | 160-180 | excitement pushes the rate up |
| auctioneer | 250+ | specialist skill, not a target |
Notice the gap between conversation and presentation. People who estimate from how they talk with friends (130 to 140 wpm) and then deliver a rehearsed talk often find they ran fast: rehearsal removes the thinking pauses, and nerves add 10 to 20 percent on top. Measure on the material, in delivery mode, and budget for the faster number.
The 150 wpm average is a planning default, and defaults are for strangers. Once you have measured 144 wpm twice on your own material, 144 is your planning number, and the difference matters: over a 10 minute talk, 150 vs 144 is a 90-word gap, more than half a minute of stage time. Professionals do not guess this; newsreaders, voice actors, and trial lawyers all know their number cold, because their time slots are non-negotiable.
Your pace also drifts by context. Most people speak 10 to 15 wpm faster on familiar material and 10 wpm slower on technical material they are reading carefully. If your talk mixes both, measure a sample of each and use the slower number for planning. It is better to finish 20 seconds early than 20 seconds late.
Sometimes the answer is not a new word count but a new pace. To slow down: mark [pause] in your script at every transition and honor it; drop your volume slightly, which forces slower articulation; and rehearse at 90 percent speed until it feels normal. To speed up: cut adjectives rather than talking faster, because rushed delivery at 180 wpm tires an audience over more than a few minutes. Pace is a tool, and like any tool it works best set deliberately: slow for the lines that matter, conversational for the rest.
Know your number. Paste any script and the calculator counts the words and shows your time at every pace, so you can plan from your measured wpm instead of the 150 average.

Read a known word count aloud at delivery pace, time it in minutes, and divide words by minutes. 750 words in 5 minutes 12 seconds (5.2 minutes) is 750 / 5.2 = 144 wpm. Repeat with a second sample and average the two.
About 150 wpm is the standard planning number for rehearsed presentations. Conversational delivery runs 130 to 150, deliberate keynote style 110 to 130, and energetic pitches 160 to 180. Clarity matters more than speed.
Over 250 wpm, which is a trained specialist skill, not a target for normal speaking. For comparison, audiobook narrators, who train for clarity at speed, sit around 150 to 160 wpm.
Adrenaline shortens pauses and quickens articulation, typically adding 10 to 20 percent to your rehearsed pace. Budget your word count for the faster pace, and rehearse slightly slower than feels natural to compensate.
For short bursts it is fine, but over several minutes 180 wpm feels rushed to most audiences and leaves no room for pauses or emphasis. If your material needs 180 wpm to fit the slot, cut words instead of speeding up.
