The counter below grades your caption against every TikTok limit, including the short 80 character bio.

        TikTok character limits

        Character limits for each TikTok field
        FieldLimitNotes
        Caption 2,200 Newer app versions accept up to 4,000 characters on some accounts. Only about 100 characters show before the More link.
        Bio 80 One of the shortest bio limits of any major platform.
        Username 24 Must be between 2 and 24 characters. Underscores and periods allowed.
        Comment 150 Comments are much shorter than captions.

        Tips for writing TikTok copy

        • Assume only the first 100 characters are visible - write a hook, not an introduction.
        • Hashtags live inside the caption budget, so budget 15 to 20 characters per tag.
        • An 80 character bio should read as one clear sentence about who you are.
        • Comments cap at 150 characters, which is shorter than most people expect.
