A comfortable fit starts here
Choose from whole US ring sizes 2–14. The measurements below let you compare a ring you own or the circumference of the finger you plan to wear it on.
Two ways to measure
Measure across the centre of a well-fitting ring’s inner circle, without including the metal. Alternatively, mark where a narrow paper strip meets around your finger, then lay it flat against a ruler.
| US size | Inside diameter | Inside circumference |
|---|---|---|
| 2 | 13.3 mm | 41.7 mm |
| 3 | 14.1 mm | 44.2 mm |
| 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 |
| 8 | 18.2 mm | 57.0 mm |
| 9 | 18.9 mm | 59.5 mm |
| 10 | 19.8 mm | 62.1 mm |
| 11 | 20.6 mm | 64.6 mm |
| 12 | 21.4 mm | 67.2 mm |
| 13 | 22.2 mm | 69.7 mm |
| 14 | 23.0 mm | 72.3 mm |
A final fit check
A ring should feel secure while passing over the knuckle comfortably. Measure at a normal hand temperature and repeat to check your result. Where a measurement falls between sizes, choose the larger whole size. Values are approximate; professional sizing can help if you are unsure.
