Why do URLs always count as 23 characters?

Twitter/X automatically shortens every URL to a t.co link of exactly 23 characters, no matter how long or short the original URL is. This tool applies that rule so your character count matches what Twitter/X will enforce.

What is the Twitter/X character limit?

Standard (free) Twitter/X accounts have a 280-character limit per tweet. Twitter Blue / X Premium subscribers can post longer content, but 280 is the universal baseline this tool targets.

Does the counter count newlines?

Yes. Each newline (Enter key) counts as one character, just as Twitter/X counts it. This matters for tweets with line breaks or bullet lists.

Is my text sent to any server?

No. All counting and highlighting happens entirely in your browser. Nothing you type is transmitted anywhere.

What counts as a URL for the 23-character rule?

Any token starting with http://, https://, or www. is treated as a URL and replaced with the 23-character t.co cost in the count. Other text is counted character by character.

Summary

The Twitter/X Character Counter counts your tweet length in real time against the 280-character limit. It detects URLs in your text and shows how many characters each one costs (always 23, regardless of URL length), so you know exactly how much room you have left. Text that pushes past 280 is highlighted in red so you can trim precisely.

How it works

Type or paste your tweet text into the input area.
The counter updates live, showing characters used and remaining out of 280.
Any URLs detected are flagged — each counts as 23 characters toward your limit.
Text beyond the 280-character limit turns red so you can see exactly what to cut.
Use the "Clear" button to reset the counter and start a new tweet.
