The right length is as long as the idea needs and no longer. Some ideas take ten seconds; some need a minute. Apps set maximum lengths, and those limits change from time to time, so check the app's help or our limits section when it is ready. A limit is a ceiling, not advice.
A way to decide
- Write the idea in one sentence.
- Film it once, without trying to fill time.
- Cut every second that does not help: a long hello, a pause, a repeated line.
- Watch it once without sound. Is it still clear? If yes, it is done.
Short is not always better
A recipe, a repair or a lesson may need more time. If each second teaches something, viewers stay. The aim is that nobody feels you wasted their time.
Test your own audience
Make a few short and a few longer videos. Look at how many viewers stay until the end for each. Your own numbers tell you more than any general advice. Keep what works, and drop what does not.

Questions people ask
Is the first second really so important?
Yes. A viewer decides within moments whether to stay. Start with the most interesting thing, not with an introduction.
