In this tip we will see how to use the terminal to change font and user interface sizes (known as font DPI settings) under Ubuntu 12.04/11.10. This will help users, who are not satisfied with the default Ubuntu font size, to increase/decrease what is displayed on your screen according to their needs.

The default Text-Scaling-Factor value for Precise is 1.0, you can check your own with this command:

gsettings get org.gnome.desktop.interface text-scaling-factor

To change it, run this command followed by your own value (Note: lower values will give your system good appearance):

gsettings set org.gnome.desktop.interface text-scaling-factor 0.8


gsettings set org.gnome.desktop.interface text-scaling-factor 1.2

If you prefer to use the GUI mode, you can install first Gnome Tweak Tool:

sudo apt-get install gnome-tweak-tool

Then start it with this command:


Go now to the Fonts tab and adjust the "Text scaling factor" option the way you like:

That's it!
