Cock ring size chart: how to measure and choose the right fit

Quick answer: what size cock ring should I get?

Measure the circumference of the exact area where the ring will sit, using a soft measuring tape or a strip of paper. Divide that circumference by 3.14 to estimate the matching inside diameter.

For a stretchy silicone ring, a diameter close to that measurement is usually the safer starting point because it can stretch. A rigid metal ring needs a more accurate measurement and must never be forced over the shaft or testicles.

If the ring causes pain, numbness, a change in colour or a deep mark, remove it immediately. Do not continue a session and wait for the feeling to return.

Circumference-to-diameter chart

This chart is a mathematical conversion using diameter = circumference ÷ 3.14. It is a measuring aid, not a promise that every body will fit the same labelled size.

• 90 mm circumference → approximately 28.7 mm diameter
• 100 mm circumference → approximately 31.8 mm diameter
• 110 mm circumference → approximately 35.0 mm diameter
• 120 mm circumference → approximately 38.2 mm diameter
• 130 mm circumference → approximately 41.4 mm diameter
• 140 mm circumference → approximately 44.6 mm diameter
• 150 mm circumference → approximately 47.8 mm diameter

How to measure correctly

• Measure the circumference at the base where the ring will sit. If the ring will sit behind the testicles, measure that position instead.
• Use a soft tape or paper strip that follows the shape without pinching the skin.
• Keep the strip level and snug against the body, but not tight enough to compress it.
• Write down the circumference in millimetres rather than relying on a clothing size.
• Measure more than once. A measurement that changes by more than a few millimetres should be repeated.

Silicone, metal and adjustable rings

Stretchy silicone is the more forgiving first purchase. It covers a wider range of fits and is easier to remove. A triple-ring design distributes pressure across three points, but every band still needs to fit without pinching.

Metal and rigid rings do not stretch. The inside diameter therefore matters much more, and a ring that cannot be removed easily is not a suitable purchase. Choose rigid rings only when the measurement is reliable and you understand the removal method.

Adjustable straps and multi-wear rings solve a different problem: they can be loosened or repositioned. They are not a substitute for checking circulation, but they are easier to adjust than a fixed circle.

How a ring should feel

A correctly fitted ring should feel snug and secure without pinching. It should not need force to get into position, and it should be easy to remove after the session.

Check the skin during use. Deep indentation, cold skin, blue or purple colour, numbness or pain are signals to remove it immediately. A vibrating motor does not change this rule; the constriction is the part that matters.

Current cock ring options

The Triangle Cock Ring is OMR 11, and the multi-wear Triangle Cock Ring Set KY24 is OMR 20. Both are stretchy starting points rather than fixed metal sizing.

The rechargeable KY37 smooth and KY38 studded vibrating rings are OMR 26 each. The difference between them is the inner surface, not the sizing system. Check the individual product page before ordering.
