How to reach 20 seconds
The length of a voiceover video comes from the words in your script, at about two and a half words a second. To reach the 15 to 20 second tier, write between 38 and 50 words. That is roughly three or four short sentences read at a calm pace.
A script for each length
- Up to 10 words, up to 5 seconds: "Freshly brewed. Ready when you are."
- Up to 20 words, 6 to 10 seconds: one clear sentence about your product and one reason to buy it
- Up to 37 words, 10 to 15 seconds: a short pitch with a problem and a solution
- Up to 50 words, 15 to 20 seconds: a mini story with a call to action at the end
What 20 seconds is good for
- A product teaser with a spoken line and a call to action
- A vertical clip for Reels, Shorts or TikTok
- A short intro for a video, a talk or a page
- A scene that needs a little time to develop
Limits worth knowing
Twenty seconds is the maximum for one clip, and each clip is a single scene. A talking photo, where a face in your photo speaks, is shorter: 4 or 8 seconds, up to about 20 words. For anything longer than 20 seconds, make several clips.
