Choosing the Right Size Penis Pump Cylinders

Penis pump cylinders are sized in relation to the girth (girth is the circumference, or distance around, the penis) of an erect penis. 

To determine which tube size is right for you, measure your girth at the thickest point of your erect penis. The thickest point of the penis varies among men, and may or may not be at the head, middle, or base of your penis.

Measure by wrapping string or dressmaker tape around the base of the shaft of your cock when erect. Divide that length by 3.142 and the result will be the diameter of your cylinder. If you choose the next nearest diameter larger it allows for expansion.
