Count your post the way X does: links count as 23 characters and many CJK characters and emoji count as two, against the 280 limit. See remaining characters as you type. Runs in your browser.
Twitter/X Character Counter helps you optimise and publish with confidence, producing clean, standards-friendly output you can paste straight into your site.
X wraps links with its t.co shortener, which is a fixed length.
Most count as two characters.
