Ring Size Guide

Our rings use US sizes. Find your size in one of two ways and compare it with the table.

Measure a ring you own

Take a ring that fits the finger you want to wear it on. Lay it flat on a ruler and measure the inside diameter in millimetres.

Measure your finger

Wrap a strip of paper around the base of your finger. Mark where it overlaps, then measure the length in millimetres. That's your circumference.

US EU Diameter Circumference
4 47 14.9 mm 46.8 mm
5 49 15.7 mm 49.3 mm
6 52 16.5 mm 51.9 mm
7 54 17.3 mm 54.4 mm
8 57 18.1 mm 57.0 mm
9 60 19.0 mm 59.5 mm
10 62 19.8 mm 62.1 mm
11 65 20.6 mm 64.6 mm

Tips

  • Measure at the end of the day, when your fingers are slightly larger.
  • Between two sizes, or stacking rings? Choose the larger size.
  • Rings with a wide band fit a little tighter.
