How low do you go?

The most common standard is one hand width below the belt buckle.

This is how I do it

I was always taught the 3 finger method (index/pointer, middle, ring finger) below kilt belt buckle. When wearing a waistcoat and no belt is required, the 3 finger method is still used. In this case since most waistcoats end where the buckle would, you make your measure from that (I hope that made sense to some one other than me). The other point of measure is of course the top of the sporran at rest (not pressed against body).
