Speaking Time Estimator
A speaking time estimator turns a word count into a runtime, so you know whether a script fits its slot before you record a single take.
How a speaking time estimator works
The calculation is one division: minutes = word count ÷ words per minute. Everything else is choosing the right speed.
Generic estimators assume around 130 to 150 words per minute. That is a reasonable default and a poor substitute for your own figure. Measure yours once with the words per minute calculator and every estimate afterwards is yours rather than an average.
Estimates at a typical presentation pace
- 150 words — about 1 minute
- 390 words — about 3 minutes
- 650 words — about 5 minutes
- 1,300 words — about 10 minutes
- 2,600 words — about 20 minutes
These use 130 words per minute. A conversational narrator at 150 will come in roughly 13 percent shorter.
Why real delivery runs longer than the estimate
Three things stretch a script past its estimate, and none of them are in the word count.
- Pauses. Deliberate silence after a key point is invisible on the page.
- Numbers and names. “2026” is one word and four syllables.
- Recovery. Live delivery includes restarts that a clean read does not.
Add ten percent to any estimate you plan to deliver live.
Speaking Time Estimator FAQ
How accurate is a speaking time estimator?
Within about ten percent if you use your own measured speed, and considerably less if you use a generic average. Pauses are the main source of error.
Should I estimate before or after writing?
Before. Knowing you have roughly 650 words for a five-minute slot shapes the draft. Discovering it afterwards means cutting work you already did.
