Ring Size Guide

We use Australian and UK letter sizing. The table gives the circumference and diameter for each letter and the US equivalent.

AU/UK Size	Circumference (mm)	Diameter (mm)	US Size
J	48.7	15.5	5
K	50.0	15.9	5.5
L	51.2	16.3	6
M	52.5	16.7	6.5
N	53.8	17.1	7
O	55.1	17.5	7.5
P	56.3	17.9	8
Q	57.6	18.3	8.5
R	58.9	18.8	9
S	60.2	19.2	9.5
T	61.4	19.6	10

Measure a Ring You Own

Choose a ring that fits the same finger. Measure straight across the inside, edge to edge, in millimetres, and match that diameter to the table.

Measure Your Finger

Wrap a thin strip of paper around the base of the finger and mark where it overlaps. Lay it flat and measure the length in millimetres. That is the circumference.

Before You Choose

Measure at the end of the day, when your hands are warm. A wider band sits more firmly, so allow a little room. If you fall between two sizes, take the larger.

Sizes by Design

The sizes available vary by design, since some forms can be made across a wide range and others cannot. Each ring page shows the sizes that piece is made in.
