How do I figure out my ring size?
Are you having troubles finding your correct ring size? It's very easy to find it if you know how to check it.
A - USING AN EXISTING RING WHICH FITS PROPERLY TO THE FINGER
Grab a ring that fits your target finger perfectly, then measure its inner diameter. Match your measurement to the chart below to get your US/Canada ring size.
Please note: Ring size can fluctuate by around half a size due to body temperature, hydration, hormones and other factors. If your measurement falls between two sizes, we recommend choosing the larger size for a comfortable fit.
| Inner Diameter (mm) | Inner Diameter (in) | US / Canada Size |
| 15.3 mm | 0.60 in | 4.5 / 5 |
| 15.9 mm | 0.63 in | 5.5 |
| 16.5 mm | 0.65 in | 6 / 6.5 |
| 17.1 mm | 0.67 in | 6.5 / 7 |
| 17.8 mm | 0.70 in | 7.5 |
| 18.4 mm | 0.73 in | 8 |
