Find your perfect fit before you order. If you are between two sizes, choose the larger size. Fingers are slightly bigger in the evening and in warm weather, so measure at the end of the day.

How to measure at home

1. Measure a ring you already own: place it on a ruler and measure the inside diameter (edge to edge, in millimetres). Match it to the chart below.
2. Measure your finger: wrap a thin strip of paper or thread around the base of your finger, mark where it overlaps, then measure the length in millimetres. This is your circumference.

International ring size chart

Find your size in the system used in your country. EU sizes follow the international standard ISO 8653, where the size equals the inside circumference in millimetres.

US / Canada	UK / Australia	EU / ISO	India	Japan	Inside diameter (mm)	Circumference (mm)
4	H	47	7	7	14.9	46.8
5	J½	49	9	9	15.7	49.3
6	L½	52	12	12	16.5	51.9

Size conversions between countries are approximate. If you are unsure, use the inside diameter or circumference in millimetres, which is the same everywhere.

Wide bands (6 mm and above) fit more snugly, so we recommend going up half to one size. Need help? Contact us and we will help you choose.
