YouTube channel description limit — Verified Sep 2026 against YouTube Help.
A strong YouTube channel description covers what the channel is, who it's for, how often you post, and why you're worth subscribing to — in 1,000 characters or less. Fill in the fields below and preview the About tab and search snippet.
Writing individual video descriptions too?
Use the YouTube description template for each video, or format the podcast show or episode description and full show notes for your podcast host at the same time.
Turning long episodes into channel content? Check clip captions against the Instagram Reels safe zone before you post.
What should a YouTube channel description say?
Five things: what the channel is, who it's for, how often you upload, why you're credible on the topic, and one call to action. A description that only says the channel name and topic in one sentence gives a new visitor no reason to subscribe.
How long can a YouTube channel description be?
YouTube channel descriptions have a 1,000-character limit. The counter above turns red past that point, and the search-result snippet preview shows how much of it actually shows up before it gets cut in search results.
Where does the YouTube channel description show up?
On your channel's About tab in full, and as a short snippet under your channel name in YouTube search results and channel recommendations — which is why the first sentence matters more than the fifth.
Can you give me channel description examples for different niches?
The structure — what it is, who it's for, cadence, credibility, CTA — works for any niche, whether that's vlogging, gaming, or education. Fill in the fields above with your own specifics and use "Start from example" to see one filled-in reference.
