If you are purchasing a ring as a gift, please see our Gifting Guide.
We want you to Crown Your Jewels with confidence befitting a King.
King Rings’ fine 2mm size granularity is unprecedented in the metal c-rings market and makes a tailored fit experience possible. Our wide bands (20mm) make the rings fit more snug than thinner bands with the same inner diameter and experiencing this difference is important.
We recommend ALL NEW CUSTOMERS start with a set of Sizing Rings, this option also provides a discount to help you discover the luxury of our metal rings.
Whether you are considering rings of this type for the first time or are a seasoned collector, our 3D printed sizing rings are the perfect way to find your best fit and compare how each of the sizes performs for you.
Most other sellers ask you to measure at home and make your best guess. The cost of getting it wrong is generally not too high but, even if you are satisfied, you may always wonder if another size might have been better. We remove all the guess work and participate with you as you find what works best.
Measure to verify size range is appropriate for you.
Sizes sold here are good for 95% of men but you might want to confirm the range is appropriate for you before buying into our refined sizing process. The following guidance was initially developed when we sold fewer sizes with just 4mm size granularity. Now, with finer sizing, these techniques are not precise enough to pinpoint a single size but work very well for range estimation.
COCK RINGS (44-58mm)
Our signature rings fit around the base of your penis behind the balls. It is important while measuring that you are warm (the boys hanging loosely) and flaccid.
Measure And Mark: While flaccid, use a string, fabric ribbon, or tailor tape and wrap it around the base of your penis behind your scrotum to get a measurement of circumference. This should be a gentle wrap, firmly against your skin but not squeezing flesh into any wrinkles. Mark the overlap, straighten out the ribbon, and measure between your two marks in millimeters or inches. Hopefully, you are within – or close to the margins of – the following range: 170mm to 240mm OR 6 5/8″ to 9 1/2″.
Simulate With Paper: Easily construct a paper ring which closely mimics the diameter and band width of our signature Tungsten Carbide rings. It wraps around your shaft, takes care of the measurement, and removes easily. Download the template with full instructions here: King Rings Sizing Ruler
GLANS RINGS (24-32mm)
Glans rings fit on the shaft of the penis, just behind the head (glans), and are a bit trickier to measure. Unlike a cock ring, which is held in place by the scrotum, a glans ring is held in place almost exclusively by its grip just behind the edge (corona) of the penis head. To fit properly, the glans ring should be loose enough to allow your penis to expand when erect, yet small enough to not slip past the corona when you are flaccid.
Measure And Mark: While flaccid, use a string, fabric ribbon, or tailor tape and wrap it around the shaft of your penis just behind the head to get a measurement of circumference. This should be a gentle wrap, firmly against your skin but not constricting. Mark the overlap, straighten out the ribbon, and measure between your two marks in millimeters or inches. Hopefully, you are within – or close to the margins of – the following range: 95mm to 130mm OR 3 3/4″ to 5 1/8″.
Other options and personalized help are available
In addition to these preparatory steps, you have the option to add sizing ring singles during checkout. This permits you to test the size you ordered before unsealing your high value ring (see our Return Policy) but you won’t have any benefit of comparison with other sizes.
If there is anything more we can do to reassure your size selection please let us know.
