Character count is the total number of characters in a piece of text — every letter, digit, space, punctuation mark and emoji adds one (or more) to the total. Most social platforms enforce a maximum character count per post.
Common limits as of 2026: X (Twitter) free 280, X Premium up to 25,000; Instagram caption 2,200; Instagram bio 150; TikTok caption 2,200; LinkedIn post 3,000; Facebook post 63,206; YouTube description 5,000.
Emojis often count as 2–4 characters because of how Unicode encodes them. Tools that show “140/280” under a tweet box are tracking this.
