Why Tweet Length Matters
Twitter's 280-character limit forces concise communication, but not all characters are created equal. URLs consume exactly 23 characters regardless of length, emojis cost 2 characters each, and CJK characters also count double. Without an accurate counter, you might think you have room when you don't — or cut content unnecessarily when you actually have space to spare.
Our tweet character counter applies the same counting rules Twitter uses internally. It detects links and applies the 23-character t.co rule, counts emojis at their true weight using grapheme segmentation, handles CJK double-width characters, and gives you a real-time visual preview of your tweet before you post it.
For longer content, the automatic thread splitter breaks your text at sentence boundaries and adds numbering, so you can draft an entire thread in one text box and copy it tweet by tweet. Every tweet in the thread stays within the 280-character limit with numbering accounted for.
Frequently Asked Questions
How many characters are allowed in a tweet?
Standard Twitter/X accounts can post tweets up to 280 characters. Twitter Premium subscribers get up to 25,000 characters. Our counter uses the standard 280 limit and automatically splits longer text into numbered threads.
How does Twitter count URLs?
Every URL in a tweet counts as exactly 23 characters, regardless of the actual URL length. Twitter's t.co shortener wraps all links, so even a very long URL only uses 23 of your 280 characters.
Why do emojis use 2 characters?
Twitter counts most emojis as 2 characters because they're encoded as multi-byte Unicode sequences. Complex emojis like family groups or skin-tone variants can use even more characters because they combine multiple code points.
Can this tool split my text into a thread?
Yes. When your text exceeds 280 characters, the tool automatically splits it into a numbered thread at sentence boundaries. Each tweet includes numbering like '1/3' and stays within the 280-character limit.
Is my text private?
Yes. Everything runs in your browser using client-side JavaScript. Your text is never sent to any server, stored, or shared. Close the tab and it's gone.
