How to tell size on '82 pattern belt

[YoshinRyu]

Yeah I know, "read the label", but I am a man and don't need no stinkin label!  :dontpanic:

Actually, anyone know how many pairs of holes are in small, medium, large belts? I figure that would be the best way to tell when the labeling wears off.

My belt is a size small(yea I'm a skinny b@stard) an it has 25 holes going across on both sides.
