Frequently asked questions

How long can a YouTube title be?

A YouTube video title can be up to 100 characters, per YouTube Help.

How long can a YouTube description be?

Up to 5,000 characters. The YouTube Data API states the limit as 5,000 bytes, so text in scripts that use more bytes per character (such as Hindi or Chinese) can hit the limit sooner.

How are YouTube tags counted?

All tags together can use up to 500 characters. The commas between tags count, and a tag that contains a space counts as if it were wrapped in quotes, so it uses 2 extra characters. This counter applies the same rule.

Should I fill all 100 title characters?

Not always. Long titles get cut on small screens and in suggested videos, so put the words that matter most at the start.
