• Use the paper to wrap around your finger. Then mark where the paper overlaps. That length in millimeters is the circumference of your finger.
• To find your ring size, refer to our conversion chart.

(If you have a big knuckle and a smaller finger below it,choose a size in the middle of these two measurements.)

Use our measurement-conversion chart to find your ring size by taking the diameter measurement in millimeters.
