gedit will use the system fixed-width font by default, but you can change the default gedit font to suit your preferences.
Select gedit ▸ Preferences ▸ Font & Colors.
Uncheck the box next to the phrase, "Use the system fixed-width font."
Click on the current font name. gedit will open a font-chooser window, allowing you to see available fonts and choose the one that you prefer.
After you have chosen a new font, use the slider under the list of fonts to set the default font size.
Click Select, and then click Close.
