Ring Size Guide
Measure precisely at home or convert your existing ring measurements.
Measurement Method
To measure the ring size using a ring that fits, you need measure the internal diameter of the ring. Write down this measurement in millimeters, and use the conversion chart below to find your ring size. If you don't have a ring to use, follow these easy steps:
Cut a string long enough to wrap around your finger.
Wrap the string snugly around the base of your finger.
Mark the exact point where the two ends meet.
Measure length from tip to pencil mark in mm.
Expert Tip: For the most accurate fit, measure your finger toward the end of the day at room temperature. If you fall between two sizes, we suggest choosing the larger size.
