Method 1: Measure a Ring

1. Find another ring that feels comfortable on the finger on which you intend to wear your ring.
2. Measure the inside diameter of the ring using a ruler or measuring tape. Make sure you use a ruler that measures in millimeters (mm). Place your ring on the ruler and measure the inside of the circle, in other words, the part that touches your finger.
3. Use our Ring Size Chart to make sure your diameter measurement is correct.

Method 2: Measure your Finger

1. Use a piece of string or paper about 10 centimeters (cm) long.
2. Wrap the paper or string around your finger where the ring should be. Pull so that the string fits snugly around your finger. It should be neither too tight nor too loose.
3. Use a pencil to mark the point where the ends of the string or paper overlap
4. Fix the string or paper to a ruler or measuring tape and measure the length (mm) from the end to the point marked with a pencil.
5. This measurement will give you the result of your finger circumference. You can find your size using our Ring Size Chart below.
