Here are the official L.A. Pump instructions on measuring cylinder sizes (table below).
- Wrap a piece of string around the thickest part of your penis. This might be around the head of the penis, or at the base. A tape measure is not recommended.
- Using a pen, mark where the string crosses itself.
- Lay the piece of string next to a ruler. This measurement will be the circumference of your penis.
- In the table below, find the corresponding Penis Outside (Circumference) measurement and the column to the right is the Cylinder tube inside diameter that you can buy inside the shop.
