To size penis cylinders measure the circumference (the distance around, or girth) of the erect penis. To do this:

  1. Wrap a piece of string loosely around your penis around the thickest part of your erect penis to measure, for some this will be the head and for others near the base.
  2. Mark where the string crosses itself.
  3. 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 sized in inches
  4. 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.)
  5. VERY important: If you are on the tail end of a diameter recomendation (for example; your circumference is 4.5; I recommend going up a quarter inch in diameter. You want to fit into the thing after all! )
  6. IF you are working on length gains primarily, a tighter fitting cylinder is best to use. One in which you fill the side walls of the cylinder quickly. This allows the tissues to expand vertically rather than horizontally.

In addition to the cylinder order size we need your cylinder length, standard lengths run from 8 inches and up. (Shorter lengths will be made upon request.) We suggest ordering a cylinder 2-3 inches longer than your erect length. For example, if you are 6 inches erect, an 8″ or 9″ cylinder length would work for you.

Two stage cylinders are sized by measuring with a string around the penis and balls (near where you would wear a penis restriction ring.) Use this measurement with the chart to determine the first stage size, the second stage should be 1″ – 1 1/2″ larger.

Plastic materials may vary in diameter up to one tenth of an inch. This does not affect fit of the cylinder.
