CB-X Sizing Guide

How to Measure for Your CB-X® Device

It is important to use this sizing guide to properly measure the penis length and diameter before purchase. Accurate penis measurements will effectively match a CB-X® Chastity device best suited for your anatomy. If you are looking to achieve a specific fit when locked up, such as tight/or more restrictive, exact measurements may not be as relevant.

To measure yourself for a CB-X chastity device, you will use two items:

  • A fabric measuring tape
  • Standard 12” ruler

Measuring Length

We highly recommend this measurement be taken in “inches”. If you are measuring in millimeters, below is a conversion chart from inches to millimeters for each cock cage.

♦ Using the standard ruler with a flaccid penis, measure from the base of the shaft to the tip of the penis head. You will compare this measurement to the cage length of our various cock cages when choosing a Chastity device.

Measuring Girth

To measure for the inside diameter (I.D.) you will need to measure the circumference of your penis. Knowing the diameter of your penis girth will assist with selecting a Chastity device by comparing your penis diameter to the I.D. of our various cock cages.

♦ Use a fabric measuring tape and wrap it around the girth of the flaccid shaft, ensuring that the measuring tape is snug but not pulled too tight.

♦ Divide this measurement by π (3.14) to find your penis diameter.

Note: For accuracy do not take this measurement directly after showering, and/or with an erect (or semi-erect) penis.

Choosing Your CB-X Device

CB-X Line of Male Chastity Devices

There are two main factors to consider when choosing a chastity device.

– YOUR ANATOMY SIZE –

If you are choosing a cock cage based on your personal anatomy size, choose the CB-X® model 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.

– YOUR FIT PREFERENCE –

Choosing a Chastity cage that is identical to your personal 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 cage should allow you to move through the day comfortably, without allowing a full erection inside of the device.

Alternatively, the Chastity experience you desire may determine the model of the device you wear or are instructed to choose by your Keyholder, regardless of personal size.

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