Wiki Pick: Changing GRUB Boot Menu Font Size

While this article is relevant to PCLinuxOS Debian Edition with KDE, it should also work with the Classic RPM edition with KDE, as well as many other desktop environments.

The Acer Spin 3 SP313-51N series laptops have a very nice 13.3 inch WQXGA (2560 × 1600) 16:10 IPS Touchscreen. That high resolution on a 13 inch screen makes the default GRUB menu extremely difficult to read. I had to use a magnifying glass to read it. Changing the display to 1920 × 1200 does not help until display drivers are loaded during boot. The only option to fix the tiny GRUB display is to change the font size that GRUB uses.

How to change the GRUB Font Size

1. Open App Menu, go to Settings, and open GRUB Customizer.

2. Enter your root password.

3. Click the Appearance Settings tab.

4. Use the Font Selection menu on the sidebar to pick a font that you like. I used Noto Sans Mono Bold.

5. Select the font size. I used 24 points.

6. Save your changes.

7. Close GRUB Customizer and Reboot to see your changes.

If you do not like the result, repeat the above steps and try a different font or size.
