We make whole US sizes only (no half sizes). Each product page shows the sizes available for that ring.
| US size | Inner diameter | Finger circumference |
|---|
| 4 | 14.9 mm | 46.8 mm |
| 5 | 15.7 mm | 49.3 mm |
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |

| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
| 13 | 22.2 mm | 69.7 mm |
How to measure
Measure the inner diameter of a ring that fits the same finger, or wrap a strip of paper around your finger and compare the circumference with the table. Measure at the end of the day when your fingers are warm, and make sure the ring can pass over your knuckle.
Wide bands (for example 8 mm) fit more snugly. If you are between sizes, choose the next size up. Tungsten rings cannot be resized, so please check your size before ordering.
If you use a printable ring sizer, print it at 100% scale. Measurements are approximate.
