Ring Size Guide

We've made finding your size simple.

This guide has everything you need across three options:

Option 1: Convert your size

We use standard UK sizing. Find your US or EU size in the table below to get your UK equivalent.

UK US EU Dia (mm) Circ (mm)
I 4 47 14.8 46.5
K 5 50 15.6 49.0
L 5.5 51 16.0 50.3
M 6 52 16.5 51.8
N 6.5 53 16.9 53.1
O 7 54 17.3 54.4
Q 8 57 18.1 56.8
S 9 60 18.9 59.3
U 10 62 19.8 62.2
V 11 64 20.6 64.7
Between two sizes? Always size up. Fingers are slightly larger in warm weather and later in the day, so measure at your largest.
Wide band rings (6mm+) sit tighter than slim bands. Please size up to the next size when ordering.
Option 2: Measure at home

Don't know your size? All you need is a thin strip of paper and a ruler.

1
Cut a strip of paper about 1cm wide and 10cm long, or use a piece of string.
2
Wrap it snugly around the base of the finger you want to wear the ring on. Tip: measure in the afternoon when fingers are at their largest, and avoid measuring when cold.
3
Mark the point where the paper meets itself with a pen, then lay it flat against a ruler. This number is your finger circumference in mm.
4
Find your circumference in the Circ (mm) column of the table above to get your UK size. If you're between two measurements, always go with the larger size.
