Social Media Character Counter

This tool checks your text against the published headline limits: X/Twitter 280 (25,000 with Premium), Instagram captions 2,200, TikTok captions 4,000, LinkedIn 3,000, Facebook 63,206, Threads and Mastodon 500, Bluesky 300, Pinterest descriptions 500, YouTube titles 100 and descriptions 5,000. It also checks SEO title tags (60) and meta descriptions (160). Platforms change limits over time, so always confirm against the current app.

Characters are counted by Unicode code point, so a single emoji counts as one character — the same way most platforms measure post length. Spaces and line breaks are counted too, because every platform includes them. Note that some networks weight certain emoji or wide characters as two; treat the count as a close, practical estimate.

No. The counter runs entirely in your browser. Whatever you type or paste stays on this page and is never sent to a server, logged, or stored, so you can safely check drafts, client copy, or anything sensitive.

If you are repurposing a post into a blog or landing page, the title tag (~60 characters) and meta description (~160 characters) control how your page shows in search results. Checking them alongside social limits lets you write copy once and confirm it fits everywhere it will appear.
