It divides your word count by a speaking rate (words per minute). Most narration runs 130–160 wpm; this tool lets you pick slow, average or fast.
At an average pace (~150 wpm) about 150 words. A 30-second spot is ~75 words, and a 10-minute video is ~1,500 words.
A calm explainer reads slower than a punchy ad. Matching the pace to your content gives a far more accurate runtime estimate.
Yes — paste as many scripts as you like. It runs in your browser, free, with no sign-up.
This is how to know how long a script will run before you record: paste your text and the timer estimates the spoken runtime from the word count and pace. It runs in the browser, free, and adds no watermark to the runtime.
Writing to a time limit — a 30-second ad, a 60-second Reel, a 10-minute YouTube video — is much easier when you can see the runtime as you write.

Speaking pace is roughly 130–150 words a minute, but a rough guess isn't enough for a tight ad. This timer converts your script's word count into an accurate estimated runtime so you can trim or expand to hit the mark.
Paste the script, read the time.

Plan to an exact length

A TikTok hook, a 30-second spot, a 60-second Reel — each has a length that performs. Use the timer to write to that limit exactly, instead of recording and discovering you're 20 seconds over.
Fit the format before you film.

No download, no sign-up — the script timer works instantly in the browser on any device.
