Back in December 2024, Ghost has introduced custom fonts:
Custom fonts
Native support for custom typography with even more control over your brand.
Team Ghost
This was a feature that was well received, but it took some changes from theme developers to make it available across custom themes.
Since Magic Pages also provides three themes, it was about time to include custom fonts as well. As of today, the themes Vienna, Berlin, and Kyiv all have custom font support.
You can update the themes directly from your Ghost theme gallery and use the fonts right away.
