The short answer
Bluesky allows up to 300 characters in the post. Bluesky counts graphemes, meaning what you see as one character, not raw code points. An emoji or accented letter counts once. A 3,000-byte UTF-8 ceiling also applies, which only emoji-heavy posts usually reach first. Tools disagree on how links count, so check the counter in the app.
What counts toward the limit
Each visible character counts once, including spaces, line breaks and emojis. A compound emoji such as a family emoji counts as one.
How much people actually see
Each post is at most 300 graphemes, so a longer idea is split into a thread of replies.
Tips for fitting your post
- Write one idea per post, then reply to continue.
- Check emoji-heavy posts against the byte limit as well as the character count.
- Keep links short where you can, since tools count them differently.
