I forget who said it, but someone had mentioned before that the "Truck Styles" page would be correct if they actually said it was for 147s only, which was the truck width they used for all their model pics and videos.
The other page in that area actually has everything listed correctly, specifically the width to the heights, as
@LebowskisRug said above which vary as the trucks get wider, they get taller.
I was wondering about the new 181s, but as they have there, same as the 161s at 53mm in height.
To make it very clear, the hangers are the one mold, just the baseplates that are different in height from cast / team to forged:
Cast / team baseplates
143, 145 and 147 at 50mm
148, 149 and 151 at 52mm
161 and 181 at 53mm
Forged baseplates
145 and 147 at 49mm
148, 149 and 151 at 51mm
161 at 52mm
