The circumference of your flaccid (soft) penis is what is used to determine the size Circle Device that you need.

Two methods to measure your circumference:

1. Place a tailor's tape measure around the middle of your totally soft Penis. Then pull the tape firmly around it. Do not allow the tape measure to be loose. Also, do not pull the tape too tight as to stop circulation. Do the measurement 3 times to make sure your measurements are consistent.
2. Place a piece of adhesive tape around the middle of your penis then firmly wrap it around to meet the tape where you started. Mark that intersection spot with a pen. Then remove the tape and place it on a straight ruler to get the perfect size you need.

IF YOUR PENIS HEAD IS SMALLER THAN THE SHAFT... If your Penis head is smaller than your shaft, then take a measurement just behind the head and another measurement in the middle of your penis. We will then make you a Tapered Circle Device that will fit you perfectly. There is an extra charge for a tapered device of $20.00 for the 12oz or 16oz Circle Devices and $40.00 for the 24oz or 32oz Circle Devices.

We ask for these measurements on the Order Form to ensure you have the correct size Circle Device.
