X counts posts by weight, not by visible characters. Latin letters weigh 1, each link counts 23 whatever its length, and emoji or CJK characters weigh 2, all against a 280 limit. A post reading 'Read', a long article link and 'now' therefore counts 32, leaving 248.
A plain character counter often disagrees with the composer on X, because X weighs characters before comparing them with the 280 limit. Long links shrink to a fixed 23 after t.co wrapping, while emoji and Chinese, Japanese or Korean characters count double. This counter applies those published twitter-text weights while you type and shows the weighted total, how many characters remain, and how many links, emoji and wide characters it found, so you can see exactly where the length went. One limit: link detection follows common patterns, so an unusual domain written without http may be counted as plain text rather than as 23. Premium accounts with longer posts are not modelled here.
Type or paste the full text, including links, mentions and emoji.
The headline number is the length X compares with 280; Characters left shows the margin.
Check the link, emoji and wide-character counts and the working to see which parts weigh more than one.

The link is shortened by t.co and counts as 23, however long the original address is.

Each kana counts double, which is why posts in Japanese, Chinese or Korean fit about 140 characters.
length = 23 × links + 2 × emoji + 2 × wide characters + 1 × other characters
linksemojiwide charactersThe text is normalised to NFC, links are pulled out and counted at 23, and the rest is split into grapheme clusters. Any cluster that is an emoji counts 2. Other code points weigh 1 if they fall in U+0000 to U+10FF or the general punctuation ranges listed in the twitter-text v3 configuration, and 2 otherwise. The sum is compared with 280.
X wraps every URL in its t.co shortener, and the wrapped link has a fixed length of 23 characters. A two-character domain and a 200-character tracking URL therefore cost the same.
The twitter-text rules give every emoji a weight of 2, including combined sequences such as a family emoji or a flag, which are made of several code points but count only once at weight 2.
Characters outside the Latin, Greek, Cyrillic, Arabic and Hebrew blocks weigh 2. CJK scripts pack more meaning into each character, so X halved their allowance when it raised the limit to 280 in 2017.
No. Arabic, Hebrew, Cyrillic, Greek and accented Latin letters all sit below U+10FF and weigh 1, the same as plain English letters.
A mention typed into the text counts like any other characters. Usernames added automatically at the start of a reply are not counted by X, so leave them out when checking a reply.
No. The count runs in your browser, and nothing you type is saved after you leave the page.
