industry standard here is 1 and 1/2 inches thick.
trust me. my best friend who i have known since 3rd grade makes granite counter tops for a living. i have 2 "cutting board" slabs he has made from counter top remanents.
the bull nose his shop makes is like 1/4" overhang
fact of the matter is, alot fo times the granite counter is just laid on the cabinet frame. at 1500lbs and more, it doesn't need much of an anchor. last install they did it took 9 strong men to carry the counter in safely.
