Got Questions About Bluesky Typography Mastery?
Can I change the font of the Bluesky app itself?
Yes! In recent Bluesky app updates, you can go to Settings > Appearance and toggle between System Font and Bluesky Font, as well as customize text scaling from Small to Extra Large.
Does changing in-app font settings change what other people see?
No. In-app appearance settings only change your personal viewing experience. To make fonts visible to everyone else on their feeds, you must use Unicode font generators.

Bluesky measures post length using Unicode Standard Annex #29 grapheme clusters. This means multi-byte emojis or complex character sequences are segmented accurately without cutting characters in half.
Is using custom fonts on Bluesky allowed under the terms of service?
Yes, 100%. Unicode characters are standard text elements defined by the Unicode Consortium and are fully permitted across the entire AT Protocol.
