Haiku defines three standard fonts for different purposes. You set plain, bold and fixed font types and sizes that will be used throughout the system.

Defaults		resets everything to default values.
Revert		brings back the settings that were active when you started the Fonts preferences.

Installing new fonts

You install new fonts by copying them into their respective user folder, i.e. /boot/common/fonts/ or /boot/home/config/fonts/ (see topic Filesystem layout).
