TikTok character limits in 2026

Field Character limit Shown before “more” Notes
Caption 4,000 ~100 In the TikTok app. Scheduling tools and the API allow 2,200.
Comment 150 — Reply to your own comment to say more.
Bio 80 — Spaces and emoji count.
Username 24 — Letters, numbers, periods and underscores.
Profile name 30 — Display name. Spaces and emoji allowed.

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.

TikTok bio, username and profile name limits

  • Bio: 80 characters. Spaces and emoji count.
  • Username: up to 24 characters, using letters, numbers, periods and underscores. It can’t end with a period.
  • Profile name: up to 30 characters, with spaces and emoji allowed. You can change it without losing followers.
