TikTok caption and bio limits, with tips
Your caption tells viewers, and TikTok search, what your video is about. Your bio and username decide whether a profile visit turns into a follow. This free TikTok character counter checks every text field against the current limits and previews how it looks.
TikTok text limits
- Caption: up to 4,000 characters in the app, hashtags included. Many schedulers still cap it at 2,200.
- Photo post title: up to 90 characters.
- Bio: 80 characters for most accounts.
- Username: up to 24 characters (letters, numbers, underscores and periods).
- Display name: up to 30 characters.
Writing captions for TikTok search
- Hook first: only the start shows over the video.
- Use searchable words: describe the topic the way people would type it ("easy 10-minute breakfast").
- Add 3–5 relevant hashtags: specific beats broad.
- End with a prompt: a question or "save this for later" invites engagement.
Make sure your on-screen text isn't hidden by the caption with the safe zone checker.
Questions
How long can a TikTok caption be?
Up to 4,000 characters in the app, including hashtags. Many scheduling tools still limit captions to 2,200 characters, so keep it shorter if you schedule posts.
How many hashtags should I use?
A few relevant ones, usually 3 to 5. Long lists of hashtags look spammy and push your actual message out of view.
How long can a TikTok bio and username be?
Bios are 80 characters for most accounts (some now get more), usernames up to 24 and display names up to 30. Usernames can only use letters, numbers, underscores and periods.
