How does X count characters?
X gives each character a weight of 1 or 2, counts every link as 23, and allows 280 weighted characters per post.
The rules come from X's open-source twitter-text library (version 3 of its counting configuration). This tool uses the same ranges:
| What you type | Counts as |
|---|---|
| Latin letters, digits, punctuation, most accented letters | 1 each |
| Chinese, Japanese, Korean characters | 2 each |
| Most emoji, including skin tones and family sequences | 2 per emoji |
| Any link (http, https or a bare domain like example.com) | 23 |
| Line breaks and spaces | 1 each |
That's why a Japanese post fills up at around 140 characters and why a long tracking link costs no more than a short one. @mentions count by their letters; the 2017 rule that hid mentions in replies from the count applies to the automatic reply prefix, not to names you type.
How do I split a long post into a thread?
Paste the full text; the right-hand column shows it split into posts of 280 or fewer, numbered if you like.
The splitter prefers paragraph breaks, then sentence ends, then spaces. Adding numbers like "2/6" takes up to six characters per post, which the splitter reserves before it cuts. Copy each part into X in order, or reply to yourself as you post. X also lets you build the thread in the composer with the + button.
When should I write a long post instead?
When you have X Premium and the text is one argument; threads still work better for step-by-step content and for readers without Premium.
Long posts keep everything in one place and one link. Threads give every step its own likes, replies and reposts, and each part can travel on its own. Many accounts use both: a long post for an essay, a thread for a checklist. Read more in best practices for writing posts.
Questions people ask
Why does my count differ from the number of letters I typed?
X counts some characters as 2. Most Latin, Greek and Cyrillic letters, digits and punctuation count as 1. Chinese, Japanese and Korean characters and most emoji count as 2. Every link counts as 23 whatever its real length.
What is the character limit on X in 2026?
280 for standard accounts. X Premium subscribers can write long posts of up to 25,000 characters; in the timeline those are cut after about 280 with a Show more link.
How does the thread splitter decide where to cut?
It fills each post close to 280, then backs up to the nearest paragraph break, then sentence end, then space, so no word is cut in half. Numbering (1/5) reserves room at the end of each post.
Does this tool post anything to X?
No. Nothing leaves your browser. Copy the text, or open it in the generator to make an image.
