Size Guide - Mk1 Cock Rings
Choosing your size
Finding the perfect cock ring size can be tricky! 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 a size based on previous experiences with other rigid cock rings (such as ones made from metal).
If you're already familiar with KINK3D chastity products and you have a base ring that fits you well, then that size will probably be the smallest cock ring you should consider. Some people, especially growers, find that they need a much larger size for a cock ring than for a chastity base ring. Please keep this in mind when picking a size.
Note: The Mk1 is a standalone product, not a chastity base ring. It is not compatible with KINK3D Cobra cages.
The size in millimeters refers to horizontal space. Each Mk1 ring has an extra 3mm of vertical space to reduce pressure under the scrotum.
| mm | in |
|---|---|
| 40 | 1.57 |
| 42 | 1.65 |
| 44 | 1.73 |
| 46 | 1.81 |
| 48 | 1.89 |
| 50 | 1.96 |
| 52 | 2.05 |
| 54 | 2.13 |
If you know the size of a metal cock ring that fits you well, these KINK3D Mk1 sizes should fit similarly. Please use these as a guide. If you're unsure and live in the US, we recommend trying our Cock Ring Packs to test out sizes to find your perfect fit.
