How to choose your size?
Put on clothes, what you want to wear the belt over. Take another belt, tighten comfortly and mark its buckle position. Put it off, lay it flat and measure the marked lenght. Let it assume you got 102 cm (39 ½ in.). Look to the chart below: 102 cm is in the gap 96-120 cm for belt size 136. You should take this size. Better if your around measurement is clother to end of the gap, but not straight in the end.
Divide cm to 2.54 to get inches.
