Tweet Counter
Count characters against X’s 280 limit as you type — with a live progress bar, remaining-character countdown, and automatic thread splitting.
About this tool
X counts every character including spaces and punctuation toward its 280-character limit. Most emoji count as 2, and every URL counts as 23 characters regardless of its real length, thanks to the t.co link shortener.
Write your post above: the bar shows how close you are, and past 280 the tool splits your text into a numbered thread at sentence boundaries where possible.
Posts between 71 and 100 characters historically get the highest engagement — the limit is a ceiling, not a target.
Everything runs locally in your browser — your text is never uploaded, stored, or shared.
Frequently asked questions
Does X count spaces?
Yes — spaces, punctuation, and line breaks all count toward the 280-character limit.
How are links counted?
Every URL is wrapped by X’s t.co shortener and counts as exactly 23 characters, whether the original link is 10 characters or 300. This counter applies the same rule.
How does thread splitting work?
Text over 280 characters is split into parts at sentence boundaries where possible (falling back to word boundaries), each with a "1/n" counter appended, ready to paste as a thread.
