Refer to our measuring guide below to find the right ring size for you.
To measure using your finger circumference:
- Wrap a string around your finger where you’d like your ring to be.
- To find your best fit, make sure that the string is pulled snugly around your finger but not too tight, it must slide easily around your finger.
- Mark the spot where the two ends of the string meet and measure the distance with a ruler in millimeters.
- Use the chart below to determine your ring size.
To measure using the diameter of an existing ring:
-
Using a ring you already own that fits well, measure the inside diameter of the ring with a ruler in millimeters
-
Note down the measurement and match it to the chart below.
-
If your size falls in-between two sizes we suggest buying the larger size.
