At your speaking pace
The same 30 minutes, at four speaking paces. Time yourself reading a paragraph aloud to find yours.

|---|---|---|
| Slow and deliberate | 120 | 3,600 words |
| Conversational | 150 | 4,500 words |
| Brisk | 170 | 5,100 words |
| Fast | 190 | 5,700 words |
Where the words go
How 4,500 words split across a 30-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 | 315 | 0:30–2:36 | Why this matters now, and what the viewer will leave with. |
| 12 main sections | 3,960 | 2:36–29:00 | About 330 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 4,500 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 30-minute script?
About 4,500 words at 150 words a minute, the pace of a relaxed conversation. Between 3,600 and 5,100 covers most speakers.
How long should the hook be?

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.
