About the TikTok Caption Character Counter
TikTok captions allow up to 4,000 characters, which makes them useful for searchable descriptions, not only hashtags. This counter shows characters, hashtags and mentions as you type.
How to use it
- Type or paste your text into the box. Your draft stays in this browser only.
- Watch the count and the “left / over” figure update as you type.
- Check the table to see which other platforms the same text fits.
- Click “Copy text” and paste it into the app.

Tips
- TikTok search reads captions. Describe what’s in the video in plain words people would search for.
- Only the first line or two show over the video, so lead with the hook.
- The bio is much shorter: 80 characters.
Frequently asked questions
Do spaces and line breaks count?
Yes. Every platform counts spaces, line breaks and punctuation as characters, so the count here includes them too.
Do emojis count as one character?
On most platforms an emoji counts as one character, but some emojis are built from several code points. X counts every emoji as two. This tool counts emojis the way each platform does where that is documented.
Is my text saved or sent anywhere?
No. Counting happens in your browser. Your draft is kept only in this browser so it survives a refresh, and you can clear it any time.
