Count characters and stay under the X limit as you write.

0 / 280 characters280 left
Quick answer

Paste or type your post into the counter above. It shows your live character count against the 280 character limit for a standard X post, flags when you go over, and marks where the text would be cut. Links count as 23 characters on X regardless of their real length.

How to use the character counter

  1. 1
    Paste your draft
    Drop your post into the box above. The count updates as you type.
  2. 2
    Watch the limit
    The counter turns red once you pass 280 characters, the limit for a standard post.
  3. 3
    Trim to fit
    Cut filler words first. If it still will not fit, that is often a sign it should be a thread.

How X counts characters

  • A standard post allows 280 characters.
  • Every link counts as 23 characters, no matter how long the URL is.
  • Emoji and many non Latin characters can count as two.
  • Premium subscribers can post longer, but the feed still rewards posts that make their point fast.
Shorter usually wins
Even when you can write long, the first line is what earns the tap. Counting characters is less about hitting the limit and more about cutting to the point.

Use cases

Fitting a punchy one liner

Check that a sharp post lands under the limit without trailing off.

Planning a thread

If a thought runs well past 280, split it into a thread instead of cramming.

Bios and replies

Use it to tighten a bio or a reply where every character counts.
