Use a ring you already own or measure your finger to find the right size before ordering.
How to measure your ring size
01
String method
Wrap a thin strip of paper or string around your finger.
Mark the point where the ends meet.
Measure the length in millimeters. This is your circumference.
Match the measurement to the chart below.
02
Existing ring method
Choose a ring that already fits the intended finger.
Measure its inner diameter in millimeters.
Match the measurement to the chart below.
Tips for an accurate fit
Measure at the end of the day when fingers are slightly larger. Avoid measuring when cold. If you are between sizes, choose the larger size.
