Comparison
YouTube Title vs Description
Both fields matter, but they do different jobs — one earns the click, the other gives context after the click already happened.
| Title | Description | |
|---|---|---|
| Max length | 100 characters (≈60–70 visible) | 5,000 characters (≈150 visible before "more") |
| Primary job | Earn the click in search/suggested | Give context, links, and timestamps |
| Visible where | Search results, suggested videos, thumbnails | Below the video player, after clicking |
| Truncation risk | High — most content is only ~60 characters wide | First ~150 characters, rest hidden behind "more" |
The title's job is to get the click — it's the first, and often only, thing a potential viewer sees before deciding whether to watch. That's why staying under roughly 60 characters matters so much: past that, search and suggested placements start cutting it off mid-sentence.
The description does its work after the click, but the first ~150 characters still matter — that preview text shows in search results under some placements too, so it's worth treating as a secondary pitch, not just a place to dump links.
