Ring Size Guide
Measure the inner diameter of a ring that fits you well. Or wrap a strip of paper around your finger, mark where the ends meet, and measure the length: that is your circumference. Match either measurement to the table below.

| 9 | 19.0mm | 59.7mm |
| 10 | 19.8mm | 62.1mm |
| 11 | 20.6mm | 64.6mm |
| 12 | 21.4mm | 67.2mm |
| 13 | 22.2mm | 69.7mm |
