About Social Media Character Counter
Every social network enforces its own character limits — Twitter/X caps posts at 280 characters (counting each t.co-shortened URL as 23 characters regardless of original length), LinkedIn posts at 3,000, Instagram captions at 2,200 (though only the first 125 show in-feed), Facebook ad headlines at 40, and YouTube titles at 100. Keeping copy within these limits prevents truncation, preserves formatting, and avoids last-minute edits when you try to publish. This counter checks your draft against all twelve limits simultaneously and highlights which platforms are close to or over their ceiling. Every calculation runs locally in your browser — your text is never sent to any server.
Private & free — this tool runs entirely in your browser.
