How to change the System Font and Icon Size of Raspberry Pi Desktop

Depending on the screen size or the usage of the Raspberry Pi, I usually tweak the font size and icon size.

If I am teaching or recording videos, I want the icon and font size to be large. If I am blogging, then I want them to be medium size. If I am using a small resolution screen then I want to change the icon and font size to a smaller proportion.

Appearance Settings

Luckily, Raspberry Pi has a Set Defaults icon for different screen sizes which makes it quick for me to change the sizes.

To change the system icon and font size of the Raspberry Pi head over to Appearance Settings and tweak the configuration there.

If you need guidance or instructions on how to navigate the settings then follow the tutorial below.

Steps on How to Change the Font Size and Icon Size in Raspberry Pi

Click on the Application Menu (Raspberry Pi icon on the upper left). Then hover over Preferences. Click Appearance Settings.

On the Appearance Settings window, click on Defaults.

Here you can select the following option.

  • Set Defaults for large screens – Set default values for high-resolution displays.
  • Set Defaults for medium screens – Set default values for medium-resolution displays.
  • Set Defaults for small screens – Set to default values for low-resolution displays.

Hovering the mouse over the Set Defaults button will show which display resolution would be the best option.

Click OK when finished adjusting the system font and icon size.

Note: I always set my Raspberry Pi background to a solid color, but when I click Set Defaults it always goes back to the default wallpaper.

I am not sure whether the initial Set Defaults size will automatically be set depending on the size of the monitor you attach to the Raspberry Pi. If you know this, let me know in the comments below.

I hope this helps.
