Changing the font size of your messages to a larger font size through the accessibility settings.

Choose from four font sizes: Small, Regular (default setting), Medium, and Large. Select a size that’s comfortable to your eyes.

Changing the font size only applies to message text, not to attachments, images, or files.

To select a preferred font size using Dynamic Type on iOS devices, see Adjust the font size.

You can also quickly adjust the font size using keyboard shortcuts.

  • Mac: Command +/-—increase/decrease font size for messages.

If you restart or exit the app, it remembers the last font size you had selected.
