HOW TO MEASURE FOR A CHASTITY CAGE

It is a good idea to accurately measure your penis length and diameter before purchasing a chastity cage. To measure yourself, you will use these items:

• A fabric measuring tape (or a string and a marker)
• A standard 12" ruler

For Accuracy:
Do not take these measurements directly after showering, and/or with an erect (or semi-erect) penis.  You may want to measure a couple of times at different times of the day to confirm your results.

Measuring Length
Using the standard ruler with a flaccid penis, measure from the base of the shaft against the pubic bone to the tip of the penis head.

Measuring Girth
To measure girth, you will need to measure the circumference of your penis. Use a fabric measuring tape and wrap it around the thickest part your flaccid shaft, ensuring that the measuring tape is snug, but not pulled too tight. Then divide this measurement by 3.14 ("pi," for those who remember their geometry) to find your penis diameter.

If you do not have a fabric measuring tape, use a string to wrap around the penis as described above. Mark the string where it crosses itself, then lay the string on the ruler to measure between the marks to get your circumference. Then divide this measurement by 3.14 ("pi," for those who remember their geometry) to find your penis diameter.

Knowing the diameter of your penis will help when choosing a chastity cage size because you will compare your diameter measurement to the inside diameter (I.D.) of various cock cages.

Choosing A Chastity Device

There are two main factors to consider when choosing your chastity device:

1. Your anatomy size
If you are choosing mainly on your anatomy size, choose the cock cage that is the closest to your penis measurements. For a first-time chastity wearer, if your penis measurement is exactly identical to a specific cock cage size, you may want to consider choosing the next size up. With that said, please also consider your fit preference (below).

2. Your fit preference
Choosing a chastity cage that is identical to your size will result in a very snug-fitting device. Some users prefer a snug fit, while some wish to have more room in their cage. A properly-fitted cock cage should allow you to move through the day comfortably, without allowing a full erection inside of the device.

Some users will begin with a cage that is identical to their anatomy size, but over time will adapt to smaller, more restrictive cage sizes, depending on the type of wear or play they are engaging in.  Some users will allow their keyholder to choose the cage size, again depending on the type of play you are engaging in.

Ultimately, you know your body and lifestyle best, so be sure to select the chastity cage that is aligned with your needs.
