# How to restore the font size and other options to default Globally

I have messed up the font size globally. I was playing with SetOptions and I think I have accidentally changed the font setting of the FronEnd setting globally as can be seen here.

I tried to uninstall Mathematical and instal it again but that did not help. how can I reset the font size to default.

You may want to try this: support.wolfram.com/kb/3274. I haven't tried it since I obviously don't want to lose my MMA settings. If it works, credits to @halirutan for pointing me to it in the chat. –  seismatica Jul 16 '14 at 7:28
