Find Your Perfect Fit
Use standard US Ring Sizing. Follow these steps for accuracy.
1
Measure an Existing Ring
Take a ring that fits the intended finger perfectly. Measure the inside diameter (not outside) in millimeters. Match it to the chart below.
2
Use String or Paper
Wrap a piece of non-stretchy string or paper around the base of your finger. Mark the overlap point, then measure the length (Circumference) in mm.
3
Visit a Jeweler
For the most accurate fit, visit a local jeweler. Ask them to measure your finger for a Standard US Fit (not comfort fit) ring.
| US Size | Inside Diameter (mm) | Circumference (mm) |
|---|---|---|
| Size 6 | 16.5 mm | 53 mm |
| Size 7 | 17.3 mm | 56 mm |
| Size 8 | 18.2 mm | 59 mm |
| Size 9 | 18.9 mm | 62 mm |
| Size 10 | 19.8 mm | 65 mm |
| Size 11 | 20.7 mm | 68 mm |
| Size 12 | 21.3 mm | 71 mm |
Pro Tip: Fingers swell slightly throughout the day or in warm weather. Measure your finger at the end of the day. If you are between two sizes, we recommend sizing up for a more comfortable fit.
