FAQ
Why does a URL count as 23 characters?
X (formerly Twitter) automatically shortens all links to a t.co URL exactly 23 characters long, regardless of how long the original link is - so this tool counts every URL as 23 characters to match.
What are "wide" characters?
Characters from scripts like Chinese, Japanese, and Korean (CJK), along with most emoji, are counted as 2 characters each under X's weighted counting rules, since they take up more visual width.
What is the current character limit?
280 characters for standard posts - this tool uses that limit, though X Premium subscribers may have access to longer posts.
Does this exactly match X's official character count?
It closely approximates X's publicly documented weighted counting algorithm, but X's exact internal implementation may handle some edge cases differently.
