Size Guide

The safest way to find out your ring size is at a jeweler. If you don’t have access to a jeweler, it would be best to apply at least two of the methods from below to have the most accurate approximation. In general, a ring is easier to enlarge than to shrink.

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 how it fits 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.
Wide rings should be 1-2 sizes larger to fit your finger.

If you intend to measure one of your rings, try to measure one with a width similar to the ring you want to purchase. Please take a potential wide knuckle into consideration. If you are not sure about your ring size, it is best to contact us and we will advise you in the best way possible.

Ring size measuring methods:


  • Find a ring, ideally a ‘band’ type ring or one with a width similar to the ring you want to purchase, which is exactly the size needed for the finger on which you will wear your new ring. Use a ruler or a caliper to measure the inside diameter of the ring and find the equivalent diameter with one of the sizes from the chart below. For example, if your ring has an inside diameter of 15.9 mm, this will correspond to size 50. If the diameter falls between two sizes, choose the larger size.

17.5mm 55
  • If you find it easier, on a piece of paper and a sharp pencil, draw the inside diameter of your ring and after that, you can measure the diameter with a ruler.
  • We also suggest that you print a paper ring sizer that you can download here. Just print it at the right scale and put your ring on it to find your ring size.
