KeyPoint size

Hello, i'm using OpenCV for some objectrecognition application. When i calculate KeyPoints with a method like SIFT the KeyPoints have a parameter size. In the documentation it says that this is the diameter of KeyPoint. My question is how this is calculatetd? Or is the parameter depending on the scale where a KeyPoint is found? And if yes, how?
