Video description limit on TikTok
The video description limit on TikTok is 4,000 characters in the app, up from 2,200. Captions posted through scheduling tools and TikTok’s posting API are still capped at 2,200, so keep scheduled captions under that.
Hashtags and @mentions count toward the limit. Only the first line or two shows on the video before “more”, so lead with the hook.
TikTok hashtags limit
TikTok doesn’t set a separate hashtag limit; hashtags simply use caption characters. Three to five relevant hashtags are usually enough.
TikTok comments character limit
The TikTok comments character limit is 150 characters, including spaces and emoji.
How to exceed the character limit on TikTok comments
You can’t post a longer comment, but you can continue the thought: post the first part, then reply to your own comment with the rest, numbering them 1/2 and 2/2. For anything longer, answer with a video reply instead.
