How It Works
Paste your post
Type or paste your X (Twitter) post into the field. The counter updates instantly as you write, so you always know where you stand against the 280-character limit.
Mind the 23-character links
On X, every URL is wrapped by t.co and counts as exactly 23 characters no matter how long it really is. Budget for it before you add a link.
Stay under 280
The progress bar turns as you approach the 280-character standard limit and shows exactly how many characters you have left for a single post.
Popular Use Cases
Write a sharper hook
About the first 140 characters show in the timeline before "Show more". Make that opening line earn the tap.
Plan around the 23-char URL rule
Every link counts as 23 characters regardless of its real length. Track your post plus its link before you publish.
Build threads that flow
Each post in a thread is still capped at 280 characters. Trim every link in the chain so it reads cleanly start to finish.
Check X Premium long posts
X Premium raises the limit to 25,000 characters. Switch the limit here to draft long-form posts and standard ones side by side.
Pro Tips
Front-load the hook
Roughly the first 140 characters appear in the timeline before "Show more". Lead with the most compelling line so people stop scrolling and expand the post.
Every URL is 23 characters
X wraps all links with t.co, so any URL, short or long, counts as 23 characters. A 280-character post with one link really gives you 257 characters of text.
Threads chain 280-char posts
A thread is just multiple posts linked together, each still limited to 280 characters. Break long ideas at natural points and keep each post able to stand alone.
Premium unlocks 25,000 characters
A paid X Premium subscription raises the post limit to 25,000 characters. Most replies and quote posts still read best when they are short, so use the headroom sparingly.

Within the limit? Now work the algorithm
Fitting 280 characters is step one. See how the Twitter/X algorithm works in 2026, learn when and how to use images on Twitter, then line up your posts with the Twitter scheduler.
