Counting rules differ
- X: weighted. Latin 1, CJK and emoji 2, any URL 23.
- SMS: GSM-7 (160 per message, 153 per part) unless a non-GSM character forces UCS-2 (70 / 67).
- Instagram, YouTube, LinkedIn: character based; some apps count combined emoji as more than one.
- Search titles/descriptions: no fixed character limit — truncated by pixel width. Ranges shown are soft guidance.
FAQ
What's the X Premium limit?
Paid accounts can post much longer, but the cap has changed several times. This page checks the standard 280 only — check X's help center for current Premium limits.
Are these official?
X's weighting follows its open-source twitter-text config. SMS figures follow GSM 03.38. SEO ranges are guidance, not rules.
