Last updated: October 8, 2026

Quick answer: Write the script, know the runtime before you hit record. This free video script duration calculator converts your word count into a precise video length at your speaking pace (slow narration to fast Shorts delivery), adds a pause buffer for natural breathing room, and breaks the script into milestone timestamps — so a 10-minute video never runs dry at minute seven. Paste your script and get the timing instantly.

Frequently Asked Questions

How many words are in a 1-minute video?
About 130–150 words at a conversational pace, up to ~180 for fast Shorts-style delivery, ~100 for slow narration.
How many words do I need for a 10-minute YouTube video?
Roughly 1,300–1,500 words at 130–150 wpm, plus a 10–15% buffer for pauses and transitions — plan for ~1,500–1,700 words total.
What speaking pace should I use?
Conversational YouTube: 130–150 wpm. TikTok/Shorts: 160–180. E-learning and meditation: 100–120. When in doubt, record yourself for 60 seconds and count.
Why add a pause buffer?
Real delivery isn't uniform — emphasis pauses, breaths, and transitions add 10–15% over the raw math. Scripts timed without a buffer consistently run long.
Does this work for podcasts and voiceovers?
Yes — the math is identical. Podcasters often use 150–160 wpm; audiobook narrators sit near 150 wpm.
How accurate is the estimate?
Within ~10% for most speakers once you've calibrated your own pace. Your first script is a guess; your tenth, measured against recordings, is precise.
