Twitter (X) character counter. Counted the way X counts.

Paste or type your post. The count follows X's own rules as you type: every link counts as 23, every emoji as 2, Chinese, Japanese and Korean characters as 2. You see what is left of 280 and of a long post, and nothing leaves your browser.

FAQ

Questions about twitter character counter

A standard post holds 280. Accounts on X Premium can write long posts of up to 25,000 characters. The counter shows what is left against both.

X weights characters. A link counts as 23 whatever its length, an emoji counts as 2, and Chinese, Japanese and Korean characters count as 2. A plain counter counts each of those as typed.

Every link counts as 23, because X wraps it in a t.co link. A long link and a short one cost the same. A bare domain counts as a link only for common endings such as .com or .io.

Each emoji counts as 2, even one built from several parts, such as a family or a flag.

This counter counts a mention like any other text, one per character. X can leave mentions at the start of a reply out of its count, so a reply may have a little more room than shown.

The weights here are X's. Other platforms count characters their own way, so use it for X posts.

Yes. It runs in your browser with no account and no limit, and the text never leaves your device.
