Script duration calculator
Turn words into estimated speaking time—or start with a target duration and calculate a practical word budget.
Estimate your delivery
Words, pace, time.
Speaking-rate results are estimates. Pauses, emphasis, breathing, demonstrations, and audience interaction all add time.

Calibrate with your own voice
Read the sample naturally. Start the timer before the first word and stop it after the last. The result becomes your speaking-rate estimate.
Clear delivery is not a race. Give each idea enough room to land, pause where the meaning changes, and keep your eyes close to the camera. A short rehearsal helps you find the pace that sounds like you instead of forcing your voice to match a generic setting.

How to interpret the result
750 words at 150 WPM is about 5 minutes.
The calculation is words ÷ words per minute = minutes. At 120 WPM, 750 words takes about 6 minutes 15 seconds. At 180 WPM, it takes about 4 minutes 10 seconds.
Deliberate
120 WPM
Useful as a slower planning estimate when a script needs space for emphasis or instruction.
Conversational
150 WPM
A practical starting estimate—not a rule for how you should sound.
Brisk
180 WPM
Useful for energetic delivery, provided the words remain clear.
Microsoft's Speaker Coach guidance treats pace as something to evaluate rather than one universal number. Published speech research also reports substantial variation between speakers and contexts; see the study indexed by PubMed. Time the delivery that fits your script.
Once the length fits, use the iPhone recording guide to set the text near the lens and reduce visible eye movement.
