X (Twitter) Character Counter and Thread Splitter

X counts characters differently than a plain text editor, which is why a post can look short and still get flagged as too long. This tool counts your post the way X actually does, treats every link as a fixed 23 characters no matter how long the real URL is, and can split a longer draft into a clean, numbered thread.

How X counts characters (and why links are different)

Ordinary letters, numbers, spaces and punctuation each count as one character toward your limit. Links are the exception: X runs every URL through its t.co shortener, and every shortened link counts as exactly 23 characters in the post limit, regardless of whether the original URL was 20 characters or 200. This calculator applies that same rule, so a post with a long link will not show an inflated count the way a plain character counter would.

Standard 280 versus Premium 25,000 characters

Free and most verified accounts are capped at 280 characters per post. X Premium and Premium+ subscribers can post up to 25,000 characters in a single post, though anything past the first couple of hundred characters gets collapsed behind a 'Show more' link in the feed. Switch the account type at the top of the tool to check your draft against the limit that actually applies to you.

Splitting a long post into a clean thread

When a draft runs over the limit, the thread splitter breaks it at word boundaries so no word gets cut mid-way, and reserves room in each post for a small '(1/4)' style counter so the numbering itself never pushes a post over the limit. Copy the result and paste each numbered post into X in order, or into a thread-scheduling tool that accepts pre-split text.
