Bluesky Character Counter
Type or paste and the count updates as you go. The big number tracks the 300-character post limit; the bars underneath show the same text against every other Bluesky field, so you can check a bio, a comment and a post without switching tools.
Every Bluesky limit
Characters are counted the way people see them: an emoji or an accented letter is one character, the same way Bluesky counts.
Bluesky character limits in 2026
Bluesky posts are 300 graphemes, which means an emoji counts as one. Display names are 64 characters, bios 256, alt text 2,000, and you can attach four images.
How Bluesky counts characters
Bluesky counts characters roughly the way you see them: an emoji is one, an accented letter is one, a line break is one. This tool counts graphemes (user-perceived characters), which matches Bluesky for everyday text. Some platforms' internals count emoji flags or skin tones as two, so if you are exactly at the limit, trim a few characters to be safe.
Writing to the Bluesky limit
- Bluesky is conversation-first. Posts that start a thread or ask a question do better than broadcasts.
- Use "Trim to limit" to cut at the boundary, then rewrite the ending rather than leaving a cut-off sentence.
- Hashtags and mentions count in full.
