With the release of iOS 16 in 2022, Apple introduced new ways to tailor your device's appearance, including the option to modify the lock screen font.

The complete list of fonts available on the iOS 16 Lock Screen is: Bold, Light, Rounded, Stencil, Serif, Serif Heavy, Slab, and Rails. Bold is the new iOS 16 default; Light matches the iOS 15 font.

You can change your font size in Signal on the secure-messaging platform's desktop, Android, and iPhone apps.
