But if you increase the radius of something it will make it bigger, not more of a circle?

When adding radius to a square you round out the corners, the more radius the rounder the corners. This is whats referred to as; "corner radius".

Ohhhhh corner radius, I thought you just meant as in radius from the sides or to the corner part, not the actual rounding on the corners. I get you now
