How to resize font size on window title bar on gnome?

Solution 1:

In Gnome 3, you can adjust titlebar fonts with gnome-tweak-tool:

Fonts > Window title font

or dconf-editor:

org > gnome > desktop > wm > preferences :: titlebar-font

or gsettings (in terminal):

gsettings set org.gnome.desktop.wm.preferences titlebar-font 'Droid Bold 10'

where Droid Bold is the name/type of your font and 10 is the size. This works as long as your titlebar doesn't use system fonts:

gsettings set org.gnome.desktop.wm.preferences titlebar-uses-system-font false

Solution 2:

You could just open

1. dconf-editor by typing that in terminal

2. go to: org > gnome > desktop > interface

3. change the titlebar font.
