YouTube Title Checker: preview your title before feeds cut it

Type a title, watch the live count against YouTube's 100-character limit, and see exactly how it truncates in desktop search and mobile feeds. Add your thumbnail for a realistic preview.

How it works

Type your title

Paste or type your video title. The counter and status update live against YouTube's 100-character limit and the optimal 20-60 range.

Add a thumbnail (optional)

Upload your thumbnail to make the previews realistic. It stays in your browser — nothing is uploaded anywhere.

Check both previews

See exactly how your title renders in a desktop search result and a mobile feed, with the truncation point marked.

Pro tips

  • Front-load your keyword and hook: the first 40 characters are the only part guaranteed to show on every surface.
  • Aim for 20-60 characters — long enough to be searchable, short enough to survive mobile feeds without truncation.
  • Never put the payoff at the end of a long title: if it gets cut, viewers see the setup but not the reason to click.
  • Numbers and brackets ("5 Steps", "[Tutorial]") scan well in crowded feeds — but keep them near the front too.
  • Read the truncated previews out loud: a title that still makes sense after the cut keeps its pull on every device.

FAQ

YouTube accepts titles up to 100 characters — beyond that, the title simply won't save. But feeds truncate much earlier, so this tool flags anything over 100 and shows you the practical cut-off points long before that.
It varies by device and surface. Desktop search and home typically show around 70 characters and mobile feeds around 60, but the exact point depends on screen width, font and language. Treat the previews as close approximations, not pixel-perfect guarantees.
Length itself isn't a ranking factor, but a title cut mid-sentence can hide the very words that make people click. Keeping the hook inside the visible range means every viewer sees your full pitch, on every device.

No. Everything runs in your browser — your text and thumbnail never leave your device, and nothing is stored once you close the tab.
