Ring size
Ring size in our configurator refers to the inner circumference in millimetres. Size 54 corresponds to an inner diameter of approximately 17.2 mm.
Inner circumference and inner diameter are different measurements. Circumference is the distance around the inside of the ring. Diameter is measured straight across the centre of the opening.
For an initial conversion, divide inner circumference by pi. For size 54, 54 ÷ pi gives approximately 17.2 millimetres. This is guidance and does not replace trying the ring on.
If you do not know your size yet
You can request your design without knowing your ring size. We will confirm the fit before you order. Width and profile are considered together. Do not simply copy someone else's ring size without checking.
