How to size penis cylinders measure the circumference (the distance around, or girth) of the erect penis.

To do this:

Wrap a piece of string loosely around your penis around the thickest part of your penis to measure, for some this will be the head and for others near the base.
Mark where the string crosses itself.
Lay the string next to a ruler to find the exact circumference. (Note - this method is much more accurate than wrapping a tape measure around the penis.)
Penis cylinders are typically sized by 'width', in US Inches. Measurements in Centimeters are also shown below. Please check that you order the correct sizes.
Find the measurement most closely corresponding to your penis circumference in the column on the left - your ideal starting cylinder size will be in the corresponding column to the right. (Cylinder Order Size is the tube’s inside diameter.) If your circumference is under 12 cm (4 3/4 inches) we recommend you start with a 3.8cm (1 1/2 inches) cylinder
Not all cylinders are available in all sizes, please ask us if you need further information
