How Long Should a YouTube Script Be? Words by Video Length

"How long should my script be?" has a simple answer: it depends on how fast the narrator speaks. Most narration for explainer-style videos runs at about 150 words per minute. That's a good planning number, and it makes the maths easy.

Words by video length (at 150 words per minute)

Video lengthScript length
3 minutesabout 450 words
5 minutesabout 750 words
8 minutesabout 1,200 words
10 minutesabout 1,500 words
12 minutesabout 1,800 words
15 minutesabout 2,250 words
20 minutesabout 3,000 words

Real narration usually falls between 130 and 170 words per minute. A calm, documentary-style voice sits lower; a quick explainer voice sits higher. Plan with 150, then adjust.

Check your own pace in two minutes

  1. Pick a paragraph of about 150 words from your script.
  2. Read it aloud the way you will in the final video, with natural pauses.
  3. Time it. If it takes 1 minute, your pace is 150. If it takes 55 seconds, you read faster (about 165); if it takes 70 seconds, slower (about 130).
  4. Use your number: script words = target minutes x your words per minute.

Remember the pauses

The words-per-minute figure already includes normal sentence pauses. But if you add long silences, music-only sections, or on-screen reading time (for a chart, say), subtract those seconds from the narration. A 10-minute video with 40 seconds of silence needs about 1,400 words, not 1,500.

Longer isn't better

Viewers don't reward length by itself; they reward a video that holds their attention. A tight 6-minute video beats a padded 12-minute one. Pick the length the story needs:

How to hit the length without padding

A beat budget for a 10-minute video looks like this: hook 75 words, setup 150, middle 900, payoff 225, close 110. See the full beat tables in our six-step workflow.
