Increase font sizes in GNOME

This post describes how to adjust the font settings in the GNOME desktop environment running on a Linux-based system.

The font sizes in the GNOME desktop can be increased to produce text that is more readable. These settings can be adjusted by giving a specific size to each font or by scaling all font sizes by a given factor. There are two ways to make adjustments to the font sizes (and other related desktop settings):

  1. gnome-tweak-tool is a settings tool with a graphical user interface.
    1. Install gnome-teak-tool if it is not already installed.
    2. Either run gnome-twek-tool from the command-line in a terminal window or press ALT-F2 and then type gnome-tweak-tool followed by ENTER.

  1. Select Fonts from the menu on the left. You can set individual font sizes or you can set the Text scaling factor to adjust all font sizes at once.

  1. gsettings is a command-line tool that can be run from a terminal or from the console.
You can use the gsettings command to set the Text scaling factor. The following command sets the Text scaling factor to 1.5:
gsettings set org.gnome.desktop.interface text-scaling-factor 1.5
