How To Measure Your Current Penis Size

Follow these instructions to measure the circumference (girth): 

Use a soft measuring tape or a piece of string. 

If you choose the latter, make sure it doesn’t stretch. 

Gently wrap the tape or string one time around the thickest part of the shaft of the erect, or semi-erect penis.

Mark where the ends of the string or tape meet.

Stretch out the string or tape and use a ruler to measure the distance from one end to the other.

This measurement should give you the circumference (girth) of your penis.

All cylinders are 10 inches long. You are choosing what width to buy.
