Social Caption Counter
See your character count against common social platform limits at a glance.
About this tool
Every social platform enforces a different character limit — X, Instagram captions, LinkedIn posts, and more. This tool checks your caption against common platform limits at a glance, so you know before you hit publish.
How to use it
- Paste your caption or post text into the box.
- Review the character count against each platform's limit shown below.
- Trim your text if you're over any platform's limit.
Tips
- Some platforms count links and emoji differently than plain characters — treat these limits as a close estimate, not an exact guarantee.
- X's limit historically applies to the visible text length, not the raw character count in every case.
- Writing shorter captions generally performs better for engagement even when a platform allows more.
FAQ
Are these limits always accurate?
Platforms occasionally update their limits — this tool reflects commonly published limits, but always double-check on the platform itself for critical posts.
