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!
KINK3D base rings are measured by inner diameter. For example, this picture shows the #2 size.
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.
Rings come in eight sizes, from diameter 1½" (about 38 mm) to 2⅜" (about 60 mm).
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.
| Size | inches | mm |
|---|---|---|
| 0 | 1 ½ | 38.1 |
| 1 | 1 ⅝ | 41.3 |
| 2 | 1 ¾ | 44.5 |
| 3 | 1 ⅞ | 47.6 |
| 4 | 2 | 50.8 |
| 5 | 2 ⅛ | 54 |
| 6 | 2 ¼ | 57.2 |
| 7 | 2 ⅜ | 60.3 |
Note: Base rings ordered through KINK3D On Demand are available in additional sizes, including half sizes.
Three ring styles
Our ring styles are carefully designed to give you control over how much space there is between the two pieces of your device. This is commonly referred to as the ball gap.
Standard Rings: 8 mm thick. These work for most people.
XD Rings: Extend forward by an extra 2.5 mm. This tightens the gap, and also makes the rings more rigid. Good for people with smaller balls to prevent escape.
Curved Rings: 5 mm backward curve at the bottom. Good for relieving pressure under the scrotum. Note: People with smaller balls can be more likely to slip through the gap with a Curved ring, defeating the purpose of the device.
We recommend starting with the standard ring, unless you're experienced with other devices and already know you need a different type.
