Font used in widgets etc

Hi
is there a global setting for the font used in footer widgets, main text etc?

I have selected a font in design settings Background & Contact Blocks but this only sets the font for headings – I want to select a font for the main body text and widgets etc – this must be a standard setting somewhere and I am missing it?

I hope I dont have to manually add css for every section on a page for the main font ?!

Thanks
Joanne
