Before buying any device we always recommend that you take your measurements first, which is the reason that we created our chastity cage and back ring measurement guide. It’s been used as a reference guide for many of our customers and some who purchase their cages elsewhere.

Regardless of where you buy your device, having accurate sizing information will help you choose a kit that’s well fitted, comfortable and secure. This is vitally important if you plan on wearing your device for days, weeks or months at a time.

We still receive many emails every week asking for sizing advice, which we’re more than happy to help with. If you ever have any sizing, measurement or other cage related questions please do get in touch with us and we’ll do all we can to help.

After reviewing our measurement guide, something we do regularly to ensure that it's up to date and as accurate as possible, we realised that we all learn differently. Therefore we decided that offering a more visual learning option should be made available. 

At that point we contacted the incredibly talented illustrator Soushiyo to discuss the production of a visual guide to help our customers. Instead, he recommended a comic format, which we loved. He got to work and produced the easy to follow guide that you can see below.

The cage featured in the comic is our very own black Hera cage.

Chastity measurement guide comic page 1 containing the side and rear view of a Hera chastity cage kit. It's covered in annotations pointing to the different sections that make up a typical ball trap cage and back ring kit.
Chastity measurement guide comic page 2 showing how to take your back ring measurement using a ruler, scissors, a pen and a length of cord. There are 4 written steps explaining each part of the measurement process.
Chastity measurement guide comic page 3 includes the mathematical formula you should use to calculate your back ring size once you've taken your measurements.
Chastity measurement guide comic page 4 showing how you should take your cage length measurement. It includes an illustration of a person holding their penis and a flat ruler and another image showing what a poorly and correctly sized cage should look like.

I hope you’ve found our guide useful and it helps you to find a device that fits you perfectly. Don’t forget, getting a cage kit that’s too big or too small could do you more harm than good, so be honest about your size and find a device that’s a safe, snug and comfortable fit.

The team involved in the production of this guide has a combined 30+ years of chastity experience, but we’re always open to learning and hearing your feedback. If you feel that there’s something that we’ve missed or a correction that you believe should be made please don’t hesitate to let us know and we'll look into it straight away.
