About this tool
Check a TikTok caption against the 2,200 character limit and test whether on-screen text clears the app's UI safe zones.
The TikTok Caption Spec Checker measures a caption against TikTok's 2,200 character field and tests whether burned-in on-screen text clears the app's interface. It counts characters by Unicode code point (so an emoji counts once, not twice), separates hashtag and mention characters from the readable hook, shows the opening 100 characters that appear before the "more" link, and maps a text block against the standard 1080 x 1920 safe-zone margins used in creator templates. Built for editors and social managers who need a caption and a title card to survive the upload without being clipped or covered.

2,200 characters. TikTok raised the caption field from 300 to 2,200 characters in 2022, and hashtags and @mentions are counted inside that same budget rather than added on top.
Roughly the first 100 characters, or about one to two lines on a phone. Everything after that is hidden behind the "more" link, so put the hook and the payoff promise at the very start and push hashtags to the end.
On a 1080 x 1920 frame, creator templates commonly reserve about 130px at the top for the tab row, 320px at the bottom for the username, caption and nav bar, 140px on the right for the like and share column, and a small left gutter. Keep titles and captions inside the remaining rectangle. These are template conventions, not a published TikTok specification, so preview the upload before publishing.
Yes. Every character of every hashtag, including the # symbol, comes out of the same 2,200 characters. This checker reports hashtag characters separately so you can see how much of the budget tags are consuming.
