What are the character limits on social media?

Every platform limits post length: 280 characters on X, 2,200 for Instagram captions, 3,000 for LinkedIn posts and 100 for YouTube titles. A social media character counter checks your text against all of them at once.

How X counts

X counts every link as 23 characters and emoji and Chinese, Japanese or Korean characters as 2, so the tool shows a separate "X weighted length". Emoji are counted as one visible character for the other platforms.

Frequently asked questions

Why is my X count different?

X counts links as 23 characters and emoji as 2, regardless of their real length.

Why is my SMS split into more parts?

Messages with emoji or non-GSM characters use Unicode encoding, which allows only 70 characters per message.

Are the limits up to date?

They reflect the standard limits published by each platform; premium accounts may allow more.
