X Post Character Counter

How the count works

X does not count every visible character equally.

X documents a standard 280-character limit and a weighted counting system. Most Latin characters count as one. Emoji, CJK characters, and many other Unicode characters count as two. Valid links count as 23 characters because X wraps them with its t.co shortener.

This counter normalises text before measuring it, recognises browser-visible emoji clusters, and applies the documented link weight. X recommends its open-source twitter-text library as the definitive implementation for API integrations.

Use the space well

Length is a constraint, not a quality score.

A post that fits can still be unclear. Once the count is valid, check whether the opening states the point, the middle supports it, and the ending earns its place.

• Keep one main idea in a standard-length post.
• Preserve the evidence or context the claim needs.
• Remove repeated setup before cutting the useful detail.
• Use a thread or linked source when the idea needs more room.

Worked editing examples

Count first, then edit the part that does the least work.

A long destination URL still uses X's documented 23-character weight, so shortening it by hand rarely creates room. A single emoji or CJK character can use two weighted characters, while a short sentence may be the clearest place to recover space.

• If a post is over the limit because of a link, keep the useful destination and remove repeated setup around it.
• If a visual symbol adds weight, keep it only when it improves meaning rather than decoration.
• If the idea needs its evidence, use a thread or link to the source instead of making the claim vague.
