GUIDE TO YOUR RING SIZE
Ring Size Guide
Find your perfect ring size by following these simple steps to accurately measure your ideal size.
1. Use a Ring You Already Own
Already have a ring that fits you perfectly? Perfect! Measure the inside diameter with a ruler and compare to the table below to find your size.
Alternatively, you can download the Ring Sizer app by Jason Withers (available on the Apple Store) and follow the instructions to measure your ring size.
| Internal Diameter (mm) | Size IT | US size | EU size |
Circumference (mm) |
|---|---|---|---|---|
| 15.3 | 8 | 4.5 | 48 | 48 |
| 16 | 10 | 5.5 | 50 | 50.2 |
| 16.5 | 12 | 6 | 52 | 51.8 |
| 17.2 | 14 | 7 | 54 | 54 |
| 17.8 | 16 | 7.5 | 56 | 55.9 |
| 18.5 | 18 | 8.5 | 58 | 58.1 |
2. Use a Piece of String or Paper
Wrap a piece of string (or paper) around your finger, mark the overlap and measure the length in millimeters. Compare your measurement to the circumference chart.
