Chastity Cage Sizing: How to Measure for the Right Cage and Ring Length
penis Length Measurement
Use a ruler to measure your penis. Measure several times a day to get your true size. Do not measure in very cold or hot weather, as these conditions give inaccurate results. Measure when the temperature is comfortable, such as after a shower.
Stand up straight and measure from your pubic bone at the base of your penis with a ruler. You can measure several times a day. If you’re choosing between two sizes, we recommend picking the standard size. If it’s hard to measure while standing, ask a trusted friend to help you. The goal is to find your smallest length when flaccid.

Penis Ring Length Measurement
At RUPIPI, most of our products come with 5 different-sized rings. These rings are measured by diameter, which is the straight distance from one side of the ring to the other.
Likewise, measure the rings at a comfortable temperature—not too hot or too cold. Use a soft measuring tape, string, or ribbon to wrap around the base and testicles to find the circumference.
You have the circumference, divide it by 3.14 to get the ring diameter.
Examples are as follows:
Circumference：175.8mm（6.92inch）÷3.14=56mm（2.2inch）
Circumference：163.3mm（6.43inch）÷3.14=52mm（2.0inch）
