Social Media Character Counter
A free character counter checks your caption length against each platform's limit in real time — X (280), Instagram (2,200), LinkedIn (3,000), and more — so posts never get cut off.
Want to plan, generate, and schedule content end-to-end? Repping.AI does it all.

What is the character limit on X?
Standard posts on X allow 280 characters; verified subscribers can post longer. The counter flags when you exceed a platform's limit.
What is Instagram's caption limit?
Instagram captions can be up to 2,200 characters, though only the first ~125 show before the 'more' cutoff, so front-load the important text.
