Determining Your Ring Size

  1. Find a piece of string or cut a strip of paper that can wrap around the circumference of your finger.
  2. Ensure it fits comfortably but snugly, and mark the point where the string or paper strip meets.
  3. Measure the distance from the starting point to the marked spot using a ruler in millimeters. This measurement is the circumference of your finger.
  4. Use the table below to match your measurement to your ring size:
Circumference (mm) Ring Size (US)
44.2 3
46.8 4
49.3 5
51.9 6
54.4 7
57.0 8
59.5 9
62.1 10
64.6 11
67.2 12
69.7 13
72.3 14
74.8 15

 

Make sure to measure your finger at the end of the day when it is likely to be at its largest. Avoid measuring your finger when it is cold, as this can result in a smaller size measurement.
