Size Guide
Rings Size Guide
Find a ring, possibly a ‘band’ type ring, which is exactly your size. Choose your size by placing the ring on the sheet: the inside diameter of the ring should match the diameter of one of the circles.
Use a ruler or a caliper to measure the inside diameter of the ring and find the equivalent diameter of one of the circles. For example, if your ring has an inside diameter of 16.6 mm, this will correspond to size 52. If the diameter falls between two sizes, choose the larger size.
Remember to measure your size at room temperature. Your fingers will usually be slightly smaller in the winter than in the summer – cold fingers in the winter – warm fingers in the summer.
The size of the ring may depend on the design of the ring and its fit on your finger. A wide ring may require a larger size and several rings worn on the same finger may also require a larger size.
Therefore order 1 size larger than you would for a single narrow ring. Please take a potential wide knuckle into consideration.
