Well not really they are for the most part genuine scale models so for example Z gauge is what N gauge is to HO/OO gauge (i.e. still in scale, but even smaller).
From largest to smaller you go; O gauge, HO/OO gauge, N gauge, Z gauge, ZZ gauge, ZZZ gauge and finally T gauge. At least those are the generally commercially available scales out there.
T gauge is truly tiny a locomotive would sit easily on the tip of a finger lol!
