How to make icon bigger in Telerik Button?

[Abhay]

Hello, I have tried several methods of making the icon within the Telerik Button bigger, but none of them worked. I tried changing the font-size of the icon, I also tried changing the Size to '"lg" but neither worked. When I make the buttons bigger, the icon stays the same size.  Any help would be greatly appreciated. Thanks in advance.
