How to Choose Your Cylinder Size

The cylinder should give you enough room to fully expand your erection. If you are filling up the cylinder, it is time to order the next size up. The cylinder should not limit the size of your erection.

Measure your penis using the instructions below to select a cylinder that fits properly and provides maximum expansion and comfort.

  • Wrap a string around the ERECT shaft near the base.
  • Mark where the ends of string meet.
  • Lay string flat and measure the distance between the two marks with a ruler.

Proper Penis Measurement

Use the chart below to determine your best size:

Penis Circumference (Inches) Cylinder Size (Opening Diameter)
