Size Guide - Base Rings
Choosing a ring
Finding the perfect ring size is one of the trickiest parts of chastity. In our experience, using a tape measure can often give a false sense of confidence and/or result in a ring that's much too large.
If at all possible, our advice is to choose your size based on previous experiences with chastity devices. If you aren't sure how our rings may compare to other products you've tried, we highly recommend the r/kink3d community on Reddit, where you can find lots of advice from experienced wearers. Or you can ask us directly!
Note: The smaller ring sizes have slightly more room in the top-left and top-right corners (compared to a circle) due to the position of the side slots.
Size 0 is very small. If you're considering Size 0, we recommend trying Size 1 first unless you're really sure.
Sizes 6 and 7 are very large. If you're considering them, we recommend trying Size 5 first unless you're really sure.
Three ring styles
Standard Rings: 8mm thick. These work for most people.
XD Rings: Extend forward by an extra 2.5mm. This tightens the gap, and also makes the rings more rigid. Good for people with smaller balls to prevent escape.
Curved Rings: 5mm backward curve at the bottom. Good for troubleshooting pressure under the scrotum. Please note that people with smaller balls can be more likely to slip through the gap.
We recommend starting with the standard ring, unless you're experienced with other devices and already know you need a different type. For those who like to geek out on detailed gap measurements, you can find further specifications here.
