X Post Counter tracks character usage against X's (formerly Twitter) 280-character limit for free accounts and 25,000-character limit for Premium subscribers. It handles X's unique character counting rules where URLs are always counted as 23 characters regardless of actual length (using t.co wrapping), and CJK characters, emoji, and some Unicode symbols count as 2 characters. The tool previews the post appearance and warns about link previews consuming visual space.
Social media managers crafting X posts, content creators planning tweet threads, and marketers optimizing post copy for maximum impact within character limits. The tool runs entirely in your browser — your data never leaves your device.
