i have all 3.
the way Fiskars advertises the sizes:
Extra-large punch design fits inside a 2" circle
Large punch design fits inside a 1.5" circle
Medium punch design fits inside a 1" circle
so those would be the sizes from point to opposite point. from what i've seen, hexie sizes in patterns are given by the length of the edge. so the finished edge sizes would be 1/2", 3/4", and 1"
