Built for people who write for the ear
Generic "words to minutes" tools are tuned for classroom presentations. This one is built for video and audio production: the pace presets match how narrators, YouTubers and commercial voice talent actually read, and the results panel tells you instantly whether your copy fits a 15, 30 or 60-second spot.
Word counts for standard commercial lengths
| Spot length | Comfortable read (≈140 wpm) | Maximum (≈160 wpm) |
|---|---|---|
| 6s bumper | 10–12 words | 15 words |
| 15s | 30–35 words | 40 words |
| 30s | 65–70 words | 80 words |
| 60s | 135–145 words | 160 words |
Leave headroom for music tails, sound design moments and legally required disclaimers — a "full" 30-second script with no air is the most common rookie mistake in commercial writing.
Why scripts always run longer than the math says
A words-per-minute calculation measures continuous reading. Real narration breathes: pauses at cuts, beats for emphasis, moments where the visuals carry the story. For narrated YouTube videos and documentaries, expect the finished edit to run 10–20% longer than the raw read time. For dialogue scenes, screenwriters use a different rule entirely — roughly one page per minute in standard screenplay format.
FAQ
How many words is a 30-second voice over script?
At a standard narration pace of 150 words per minute, a 30-second spot holds about 75 words. Broadcast commercials often read slightly slower for clarity — 70 words is a safer ceiling if the spot includes a phone number, disclaimer or call to action.
How many words per minute is normal for speaking?
Conversational speech runs 120–150 wpm. Professional voice over narration averages 140–160 wpm. Audiobooks are read closer to 150–160 wpm, while fast promo and trailer reads can hit 170–190 wpm. When in doubt, time it at 150 wpm.
How long does a 1,000-word script take to read aloud?
About 6 minutes 40 seconds at 150 wpm, 7 minutes 40 seconds at a relaxed 130 wpm, or just under 6 minutes at a brisk 170 wpm. Use the calculator above with your own pace for an exact figure.
Does this work for YouTube video scripts?
Yes — paste your script and use 140–160 wpm for typical YouTube narration. Remember to add time for b-roll pauses, on-screen demos and breathing room: most creators find their final video runs 10–20% longer than the raw read time.
Is my script uploaded anywhere?
No. The word count and timing math run entirely in your browser. Your script never leaves your device — nothing is stored, logged or transmitted.
