# Fonts

Manage the fonts used to display text.

## Discussion

The [`NSFont`](/documentation/AppKit/NSFont) and [`NSFontManager`](/documentation/AppKit/NSFontManager) classes encapsulate and manage font families, sizes, and variations. The [`NSFont`](/documentation/AppKit/NSFont) class defines a single object for each distinct font; for efficiency, these objects, which can be rather large, are shared by all the objects in your app. The [`NSFontPanel`](/documentation/AppKit/NSFontPanel) class defines the font specification panel that’s presented to the user.
