Bluesky character counter
Real-time 300-character counter for Bluesky posts with link preview handling.
about the bluesky character counter
Bluesky posts are limited to 300 characters — slightly more than X's 280, but the same tight discipline applies. This free counter shows your count in real time, including how links are handled: Bluesky renders link card previews and the URL itself does not count toward the 300-character limit, unlike X's t.co wrapping behavior.
300 characters rewards precision. Posts that use the full limit often outperform shorter ones — there is no penalty for using the space, and Bluesky's culture is more conversational than X's, so a bit more context usually works.
Writing a Bluesky thread? The 300-character limit applies to each post in the thread. Use this counter to draft each one before you post, then schedule the whole thread via PostAI's Bluesky scheduler.
