How long should a TikTok, Reel or Short be?
4 min read · Updated
People like a single number, but there isn’t one. Platforms change their maximum lengths and how they treat different durations, so treat any universal rule with suspicion. A better approach is to match length to the idea and then test.
Let the idea set the length
A single joke or tip may take ten seconds. A story with a setup and a payoff may need a minute or more. Padding a short idea to hit a target length makes it worse; cutting a story short so it no longer makes sense makes it worse too.
Front-load the point
Whatever the length, the first seconds should show the viewer why to stay. Start at the interesting part, not with an introduction. A headline over the video can do some of that work.
Cut anything that doesn’t earn its place
Remove long pauses, repeated phrases and tangents. Tighter clips tend to feel more energetic, as long as they stay clear. Watch your own clip and note where you would swipe away.
Test, don’t guess
Post a few clips of different lengths on the same topic and compare how people watch them in each platform’s own analytics. Your audience and subject matter matter more than averages other people publish.
Platform limits and recommendations change over time, so check each platform’s current guidance before you plan.
Plan your script length
If you narrate, a relaxed pace is roughly 150 words per minute. Use that to size a script to the length you want, then adjust after you hear it.
Common length mistakes
Most length problems are really structure problems:
- Starting with a slow introduction before the point
- Repeating the same idea in different words to fill time
- Ending abruptly before the payoff, or dragging on after it
- Choosing a length first and forcing the idea to fit
A simple way to test length
Pick one topic and make three versions: a tight cut, a medium cut and a fuller version. Post them on different days at similar times, then compare how long people watch and how many finish each one in the platform’s own analytics. Repeat with another topic before you decide anything, because one result can be a fluke.
Be consistent within a series
If you publish a recurring series, a consistent length helps viewers know what to expect and makes your own testing cleaner. Change one thing at a time so you can tell what made the difference.
