I am having a problem with the default font sizes for GTK apps in openbox being too large. I do not quite understand how to fix the issue. They do not follow the settings set from within un or from gnome-tweak-tool

Try using lxappearance, which you can install in the typical manner. –  Chan-Ho Suh Jul 6 '12 at 5:39

On startup, run whichever of these works better for you.


Or, you can try changing your screen DPI in the file ~/.Xresources. Just insert something like this. (Smaller numbers give smaller font sizes)

Xft.dpi 90
