Twitter Character Counter
Count characters for X in real time, exactly the way X counts them: URLs always count as 23 characters, and emoji count as two. See your remaining characters, and split long drafts into a clean thread automatically.
Paste or type your draft — the counter updates live with X's real counting rules.
Watch the remaining-characters indicator; links are counted as 23 characters no matter their length.
Over the limit? Use the thread splitter to break your draft into numbered posts at sentence boundaries.
Frequently asked questions
How does X count characters?
Most characters count as 1, but every URL counts as exactly 23 characters (they're wrapped by t.co), and most emoji and CJK characters count as 2. The standard limit is 280 characters for free accounts.
Do links shorten my available characters?
Every link costs exactly 23 characters regardless of its real length. A 100-character URL and a 20-character URL both take the same space.
What's the character limit with X Premium?
Premium subscribers can write up to 25,000 characters, but posts over 280 get collapsed with a 'Show more' link — short posts still tend to earn better engagement.
