Bluesky Character Limit — Everything You Need to Know

What is Bluesky's character limit?

Bluesky allows 300 characters per post. This is slightly more than Twitter's 280 limit but the platform culture favors shorter, more conversational writing. Posts in the 150–250 character range tend to get more engagement than posts that use the full 300.

Do hashtags work on Bluesky?

Technically yes — hashtags count toward your 300 character limit and can aid discoverability. But culturally, hashtag-heavy posts are associated with Twitter-style posting that Bluesky's core audience actively rejected. Most successful Bluesky creators use no hashtags at all, or at most one very specific one.

How is Bluesky different from Twitter for content?

Bluesky rewards conversational, genuine writing over broadcast- style content. The platform's core user base is people who left Twitter because they were tired of performance and algorithmic optimization. Content that feels native to Bluesky tends to be lowercase, specific, and written for one person rather than an audience. For a detailed breakdown of how to adapt content between the two platforms, read our Twitter and Bluesky cross-posting guide.
