Setting type/size of font in preferences too large and pressing "Apply" button.

I set the type/size of the font on the "General" tab of the "Preferences" too large and clicked the "apply" button. Now the type/size of the font is off the bottom of the screen.

I tried re-installing it but the same issue remains.

I tried looking around but I am new to Linux.

Any help you have will be greatly appreciated!
