Estimated runtime
Paste a script or enter a word count to see the runtime.
| Video length | Slow & deliberate | Conversational | Fast & energetic |
|---|---|---|---|
| 1 min | 110–130 | 140–160 | 170–200 |
| 3 min | 330–390 | 420–480 | 510–600 |
| 5 min | 550–650 | 700–800 | 850–1,000 |
| 8 minMid-roll | 880–1,040 | 1,120–1,280 | 1,360–1,600 |
| 10 min | 1,100–1,300 | 1,400–1,600 | 1,700–2,000 |
| 15 min | 1,650–1,950 | 2,100–2,400 | 2,550–3,000 |
| 20 min | 2,200–2,600 | 2,800–3,200 | 3,400–4,000 |
| 30 min | 3,300–3,900 | 4,200–4,800 | 5,100–6,000 |
This counts spoken words, so it's a floor rather than a length. B-roll, demos, screen recordings, music beds, pauses for effect and anything you show instead of say all add runtime the word count can't see. Scripts routinely shoot 20–30% longer than this estimate, and heavily visual ones far more.
The pace bands are ranges because delivery isn't a constant — the same person reads faster on a re-take, slower when explaining something hard. Record yourself reading 200 words and time it if you want your own number; that beats any benchmark here.
Length is not a strategy. Writing to hit 8:00 for the mid-roll is the most common way a good script turns into a padded one — viewers leave, and average view duration falls further than the extra ad slot is worth.

The arithmetic is simple — words ÷ words-per-minute = runtime— but the words-per-minute figure is the part everyone gets wrong. It isn't a constant. Careful tutorial narration runs near 120, ordinary talking-head delivery around 150, and fast edited commentary close to 200. That's nearly a factor of two, so the same 1,500-word script is a 7-minute video or a 13-minute one depending entirely on who reads it. This tool works in bands for that reason.
How many words for a 10-minute video
About 1,400–1,600 words at a conversational pace, or 1,100–1,300 if you speak deliberately. Aim at the lower end of whichever band fits you: everything you showrather than say adds runtime the word count can't see, and a script that overruns gets cut in the edit anyway. The table above covers every common length at all three paces.
The one length rule that's real
Videos over 8 minutescan carry mid-roll ads. That genuinely changes the revenue on a monetized video, and it's why so many scripts are written to land just past it — and why so many of them drag. Padding to reach the mark costs you average view duration, which costs you more than the extra ad slot returns. If the idea is a six-minute idea, make a six-minute video. Everything else you've read about an ideal length is folklore — the same kind we went through in 5 YouTube SEO myths costing you views.
Where the extra minutes come from
Spoken words are the floor. B-roll, screen recordings, demos, music beds, laughs and pauses for effect all sit on top, which is why a 10-minute estimate routinely shoots at 12 or 13. If you're planning chapters around the runtime, the chapters validator checks the timestamps will actually build once you have the real video, and the description checker handles the description they live in. Writing a Short instead? The Shorts length checker covers which lengths actually perform under 3 minutes.
The hard part isn't the word count
Knowing a video needs 1,500 words doesn't tell you which 1,500. That's the part VidHalodoes: it reads the transcripts, chapters and comments of the videos already ranking for your topic, then writes the outline chapter by chapter — what to cover, in what order, and the questions the current top videos leave unanswered. You bring the delivery; the research is already done. And if the reason you're counting words is watch time, the watch hours calculator shows what your average view duration is actually worth against the 4,000-hour threshold.
Frequently asked questions
How many words is a 10-minute video?+
Roughly 1,400–1,600 words at a conversational pace of 140–160 words per minute. A slower, tutorial-style delivery needs about 1,100–1,300; a fast, tightly edited vlog can run to 1,700–2,000. Those are spoken words only — b-roll, demos and pauses push the finished video longer, so aim at the lower end of the band.
How many words is a 5-minute video? A 20-minute one?+
About 700–800 words for 5 minutes and 2,800–3,200 for 20, at a conversational pace. The table above gives every common length at all three pace bands. The relationship is linear, so you can scale it: multiply the minutes by your words-per-minute.
How many words per minute do people speak?+
Somewhere between about 110 and 200 depending entirely on delivery. Careful tutorial narration sits near 120; ordinary conversational YouTube delivery lands around 150; fast, energetic commentary with the pauses edited out reaches 180–200. There's no single correct figure, which is why this tool works in bands. Time yourself reading 200 words if you want a number that's actually yours.
How long should a YouTube video be?+
As long as the idea earns and no longer. There's no length that ranks better — what matters is whether people keep watching, and padding is the fastest way to lose them. The one real length rule is that videos over 8 minutes can carry mid-roll ads, which is a monetization decision, not a quality one.
Why is my finished video longer than the estimate?+
Because the estimate counts words, and video contains a great deal that isn't words. Every screen recording, demo, cutaway, reaction beat and deliberate pause adds time no word count can predict. A script that estimates 10 minutes routinely shoots at 12 or 13, and a heavily visual one can double.
Should I write a full script or bullet points?+
Either works, but they land at different word counts — a full script is what this calculator measures, while bulleted notes get improvised around and usually run longer per point than they read. If you work from bullets, time a recorded minute and use that as your own words-per-minute figure.
Does the calculator count stage directions?+
Not by default. Anything in [square brackets] is treated as a direction rather than dialogue and left out of the count, since you don't say it aloud. Untick the box if your script uses brackets for spoken text.
