Work out how long a script takes to read aloud, or how many words fit a 30-second intro or a 60-second ad read — at a slow, average or fast pace, or your own.

Open Episode modeConverts between a number of words and the time it takes to say them, using a speaking pace in words per minute. The average is 150 words per minute — the National Center for Voice and Speech's figure for English speakers in the US — with slow and fast presets 30 words either side, or your own measured pace.
Every result is shown at your chosen pace and at all three presets side by side, because nobody reads at exactly one speed: the slow-to-fast spread is the range your recording will probably land in. Scripts with pauses, music beds or ad breaks run longer than the words alone.
The National Center for Voice and Speech gives the average rate of speech for English speakers in the United States as about 150 words per minute. That's an average, not a rule — pace changes with the speaker, the language, the material and whether it's read or spoken off the cuff.
This calculator's slow (120) and fast (180) presets are simply 30 words per minute either side of that average, to show the range — they're not a published standard. Your own measured pace is always the better number.
Intros, ad reads and trailers have hard time slots, and a script that's 20% too long is only discovered in the edit. Knowing the word budget up front means writing to the slot instead of cutting to it.
