X (Twitter) character counter
Paste your post and see exactly how it fits X's 280-character limit, with every URL counted the way X counts it.
X allows 280 characters per post on free accounts and up to 25,000 characters for X Premium subscribers. Every URL counts as exactly 23 characters no matter how long it is, media attachments count as zero, and usernames at the start of a reply are not counted.
X (Twitter) character limits
What counts, and what doesn't
- Every link counts as 23 characters, even if the URL itself is longer or shorter. X wraps all links through t.co.
- Images, GIFs, videos, and polls do not use any characters.
- In replies, the @usernames of people you are replying to do not count toward the limit.
- Emoji usually count as 2 characters each because X counts most emoji as two units.
Frequently asked questions
How many characters can an X post have?
280 characters on a free account. X Premium subscribers can post up to 25,000 characters, though only the first few lines show before a Show more link.
Do links count toward X's character limit?
Yes, but every link counts as exactly 23 characters regardless of its real length, because X wraps links with its t.co shortener.
What happens if my post is over 280 characters?
X rejects it unless the account has Premium. If you schedule an over-limit post through a tool, it fails at publish time, so trim it first or split it into a thread.
