About this tool
Platform character limits differ and emoji weight varies — posting over limit truncates captions or blocks publish.
Count in real time as you write to avoid emergency edits in the social app.
How to use the Caption Character Counter
- 1
Type or paste your caption into the counter.
- 2
Select the platform to see its character limit and current count.
- 3
Trim or edit until you are within the limit before posting.
Limit awareness
Instagram captions allow 2,200 characters but front-load hooks — most users see only the first line.
LinkedIn allows 3,000; TikTok captions are shorter — prioritize keywords early.
Pro tips
- Write hook in first 125 characters for Instagram preview fold.
- Use thread splitter if content exceeds single-post limits on X.
