Our sized rings are offered in US sizes between 4 and 10, depending on the style. If you do not know your size, you can find it at home in a couple of minutes with a strip of paper or with a ring you already own.
Measure your finger
- Cut a thin strip of paper, or take a piece of string that does not stretch.
- Wrap it around the base of the finger you will wear the ring on. It should feel snug but still slide over the knuckle.
- Mark the point where the end meets the strip.
- Lay it flat against a ruler and measure the length in millimeters. That number is the inside circumference in the chart below.
Or measure a ring that fits
Take a ring that fits the same finger well and lay it on a ruler. Measure straight across the inside of the ring, from inner edge to inner edge, in millimeters. That number is the inside diameter in the chart below.

Tips for a good fit
- Measure at the end of the day, when your fingers are at their largest. Cold hands measure smaller.
- Measure two or three times to be sure.
- If you are between two sizes, choose the larger one.
- If your knuckle is wider than the base of your finger, pick the size that slides over the knuckle comfortably.
- Not sure, or buying a gift? An adjustable ring has an open band and fits most fingers.
