How Many Characters Is a Tweet? X (Twitter) Character Limits in 2026

The short answer: a standard post on X (Twitter) is limited to 280 characters. X Premium subscribers can publish long-form posts up to 25,000 characters, but only the first 280 show in the timeline before a "Show more" fold — so for reach, 280 is still the number that matters.

The character limits at a glance

• Standard post: 280 characters.
• X Premium / Premium+ long-form post: up to 25,000 characters (first 280 visible before the fold).
• Bio: 160 characters.
• Display name: 50 characters.
• Username (handle): 15 characters.
• Direct messages: 10,000 characters.

How X actually counts characters

X does not use a naive string length. It uses a weighted count: most Latin letters, numbers and punctuation count as 1; CJK characters (Chinese, Japanese, Korean) count as 2; and every URL is normalized to exactly 23 characters no matter how long the real link is. Most emoji count as 2, and emoji with skin-tone or zero-width-joiner modifiers can count for more.

This is why a draft that looks like it fits can still be rejected — a couple of emoji and a long link quietly eat 30+ characters. A weighted counter that mirrors X's rules removes the guesswork.

Writing within the limit for maximum reach

1. Front-load the hook — the first ~70 characters are what shows in dense feeds and notifications.
2. Cut filler words ("just", "really", "I think") before cutting ideas.
3. Replace long links with the point; the link costs 23 characters whether or not it adds value.
4. If the idea genuinely needs more than 280 characters, split it into a thread rather than relying on the Premium fold.

When a post runs long, a thread almost always outperforms a single long-form post, because each thread tweet stays above the fold and the reply-chain structure is weighted by the 2026 algorithm.
