YouTube tag generator

Tag lists that fit YouTube's 500-character limit.

Quick answer

YouTube allows 500 characters of tags. Commas count, and a tag with a space counts 2 extra characters. Tags matter most for common misspellings.

How YouTube counts tag characters

500 characters in total
tag characters + commas + 2 per tag with a space
YouTube treats a tag with a space as if it were in quotes, so “sourdough bread” costs 17 characters, not 15.
Use tags for misspellings
YouTube says tags play a minimal role in discovery. They help most when people often misspell your topic.
Spend effort on the title
The title, thumbnail and description matter more. Add a short, relevant tag list and move on.

How many tags can a YouTube video have?

There is no set number. All tags together must fit in 500 characters, including commas and 2 extra characters per multi-word tag.

Do YouTube tags still matter?

A little. YouTube says tags play a minimal role in discovery and help most when your topic is often misspelled.

Should I copy tags from popular videos?

Only if they describe your video. Unrelated tags can break YouTube's policy on misleading metadata.
