At your speaking pace
The same 20 minutes, at four speaking paces. Time yourself reading a paragraph aloud to find yours.
| Pace | Words a minute | Script length |
|---|---|---|
| Slow and deliberate | 120 | 2,400 words |
| Conversational | 150 | 3,000 words |
| Brisk | 170 | 3,400 words |
| Fast | 190 | 3,800 words |
Where the words go
How 3,000 words split across a 20-minute video, at 150 words a minute.
| Part | Words | Runs | Its job |
|---|---|---|---|
| Hook | 75 | 0:00–0:30 | Confirm the click, open a question, promise the answer. |
| Setup | 210 | 0:30–1:54 | Why this matters now, and what the viewer will leave with. |
| 8 main sections | 2,565 | 1:54–19:00 | About 320 words each. Open each one with a reason to keep watching. |
| Close | 150 | last 1 min | Pay off the hook, then one call to action, not three. |
What changes at this length
- Mid-roll ads open up at 8 minutes
- YouTube lets monetized channels place mid-roll ads in videos that run 8 minutes or longer. Only stretch a video to reach 8 minutes if the extra minutes are worth watching: viewers who leave early cost more than an ad slot earns.
- Re-hook every two or three minutes
- Attention dips at section changes. Open each new section with a short line that gives the viewer a fresh reason to stay: a question, a stake, or a hint of what is coming next.
- Add chapters
- Write the section titles so they double as chapters. YouTube shows chapters when the description lists at least three timestamps, the first at 0:00, each chapter at least 10 seconds long.
- Research before you write
- A script this long is 3,000 words or more. Gather your facts and sources first and outline every section before drafting: long videos lose viewers to vague middles, not to slow intros.

Questions
How many words is a 20-minute script?
About 3,000 words at 150 words a minute, the pace of a relaxed conversation. Between 2,400 and 3,400 covers most speakers.
How long should the hook be?
Plan the first 30 seconds, about 75 words, as the hook: confirm the viewer clicked the right video, open a question, and promise the answer.
Should I write every word or use bullet points?
Write every word if you read from a teleprompter or record a voiceover; use talking points if you are natural on camera. Either way, plan the word budget per section so the video lands on time.
