Ring Size Chart

1. Measure your finger

Take a strip of paper, a pen, and a ruler. Cut the paper to about 10 cm in length and wrap it around the finger where you want to wear the ring. Make a small mark where the paper overlaps. Then use a ruler to measure the length from the beginning of the paper to the mark you made. This length in millimeters is your ring size. For example, if the distance is 54 mm, your ring size is 54.

2. Use a ring that already fits

Take a ring that fits you well and measure the inside diameter with a ruler. Multiply that number by 3.14 to find the ring size. For example, if the inside diameter is 17.2 mm, 17.2 x 3.14 = 54. This means your ring size is 54. You can also use our size chart if you know your size in another country. If your result is between two sizes, we recommend choosing the larger size — especially if the ring has a wide band.
