Size guide
1. Get an erection
In order to measure yourself correctly your penis must be in an erect state. This will provide the most accurate method of ensuring you choose the correct pump. You will then be able to select a pump from the four ranges provided.
2. Measure your length
Measure your erect penis with a rule pressed lightly onto your pubic bone. You`ll find using a measuring gauge is easier than a ruler. Record the measurement from the pubic bone right up to the tip of your penis. You will need this measurement later.
3. Measure your girth
Measure your erect penis with a rule pressed lightly around the thickest part of your penis. Again, you`ll find using a measuring gauge is easier than a ruler as it bends with ease. Alternatively use a piece of string to get the circumference and then measure this with a ruler. Record the measurement from the full circumference your penis. Enter your measurements into the calculator to discover your perfect pump.
