How to configure the size of the FontAwesome icons?

Hooked up on the font FontAwesome
But I can't configure the size of icons. They propose to add classes ( fa-2x, fa-3x, fa-4x, fa-5x ), but it doesn't quite fit. I need a certain size. When I was in CSS I write font-size: 30px; it does not help.
How to solve the problem?

See what classes are "fa-2x, fa-3x, fa-4x, fa-5x":

So you just have to correctly specify the font-size.

you are doing something wrong - the ESSENCE of an icon font that this font is LEGO change the size and color.
if you can't set the size via the font-size so that entire font-size with a higher priority.
