How to use the TikTok caption counter
- Type or paste your video caption into the Caption box.
- Watch the characters left out of 4,000 and the hashtag and mention counts.
- Check the preview to see roughly what shows before the caption is shortened.
- Use the Bio box to keep your profile bio within 80 characters.
How the TikTok caption counter works
TikTok captions can be up to 4,000 characters long, including hashtags and mentions, and profile bios up to 80 characters. The counter checks both as you type, with a bar that turns amber near the limit and red once you go over.
On the For You feed, only the start of a caption shows over the video before it is shortened. The preview shows roughly the first 100 characters, so you can check the opening still makes sense on its own. Emoji count as one character each here.
Formula
Characters left = 4,000 − characters used. Hashtags are counted as words starting with # and mentions as words starting with @.
Example
A 180-character caption with 4 hashtags leaves 3,820 characters. The preview shows its first 100 characters, followed by more.
The bio "Easy 15-minute dinners 🍝 New recipe every day" uses 45 characters, leaving 35.
Tips and common mistakes
Say it in the first line
Viewers read the caption while the video plays. Keep the key line short and put details later.
Use hashtags that describe the video
A few specific hashtags help people find the video better than a long list of generic ones.
Cross-posting to YouTube Shorts?
Check your title in the YouTube title and tag counter, where the limit is just 100 characters.
Reusing the caption on Instagram
Instagram allows only 2,200 characters and 30 hashtags; check it with the Instagram caption counter.
Add text in the video too
On-screen text and spoken words reach viewers who never open the caption. Use the caption for context, searchable keywords and a call to action.
Keep your bio specific
With only 80 characters, say what your videos are about and how often you post, rather than a general slogan.
