How It Works
Paste your post
Type or paste your Bluesky post into the field. The counter updates instantly as you write.
Stay under 300
The progress bar turns as you approach the 300-character limit and shows exactly how many characters you have left.
Reuse it everywhere
Compare the same text against X, Threads, Instagram, and the rest so one draft works across your whole network.
Popular Use Cases
Reach early adopters
Bluesky skews toward an engaged, early-adopter audience. Keep posts tight and conversational to land with that crowd.
Budget for links and tags
Links, mentions, and hashtags all count toward the 300-character limit. Track the full post before you send it.
Repurpose across platforms
See instantly whether your Bluesky post also fits X, Threads, LinkedIn, and the rest before scheduling.
Post to the open network
Bluesky runs on the decentralized AT Protocol. The same 300-character limit applies wherever your post is rendered.
Pro Tips
300 characters rewards brevity
Bluesky gives you more room than X but less than Threads. Lead with your point: a single sharp idea per post performs best.
Bluesky counts graphemes, not code points
Bluesky counts visible characters (graphemes), so most emoji count as one. A complex emoji that looks like several characters still counts as a single grapheme there.
Links count as their full text
Unlike X, Bluesky does not shorten URLs to a fixed length. A long link consumes its full character count, so keep URLs lean.
Built on an open protocol
Posts live on the AT Protocol and can appear across different clients. Write for portability: avoid client-specific formatting tricks.
