Circumference and Diameter

Dear Customers,

We supply our sizes in the U.S. numbered way as we do find that this is a far more universally used size. Please see above for other sizes and measurements.

How To Measure Your Ring Size

You can do this a number of ways, here are a couple.

If you use an exsisting ring that fits nicely on the finger of your choice. Then using a ruler measure the diameter of the ring. Then check with the corresponding measurements with the chart above to find your correct size.
With a piece of string, ribbon or anything simular. Wrap it around the finger of choice and mark the place it overlaps. then with a ruler measure this piece of string to the mark and this will be your circumference. Then check with the chart above to find your correct size. When using this method, remember that you have to get the ring over your knuckles, so size may need to be made a bit larger.

If you are choosing a wide band ring it is sometimes better to choose a 1/2 size larger.
