How to find your ring size

Australia sizes rings by letter, and many rings come in half sizes too. The quickest way to know yours is to come in and have it measured.

At home, there are two ways. If you own a ring that fits the right finger, measure straight across the inside in millimetres and check it against the chart below. If you don't, cut a strip of paper about 10cm long, wrap it round the finger where the ring will sit, mark where it overlaps, then lay it flat and measure to the mark. That is your finger's circumference.

Size Inside diameter Circumference
H 14.9mm 46.8mm
I 15.3mm 48.0mm
J 15.7mm 49.3mm
K 16.1mm 50.6mm
L 16.5mm 51.9mm
M 16.9mm 53.1mm
N 17.3mm 54.4mm
O 17.7mm 55.7mm
P 18.1mm 57.0mm
Q 18.6mm 58.3mm
R 18.9mm 59.5mm
S 19.4mm 60.8mm
T 19.8mm 62.1mm
U 20.2mm 63.4mm
V 20.6mm 64.6mm
W 21.0mm 65.9mm

Measure in the afternoon, when your hands are warm. Fingers are smaller first thing in the morning and on cold days. If you land between two sizes, go up.

Most gold and silver rings can be resized. A few can't: titanium and tungsten are too hard to work, and a ring with stones set all the way around has nowhere to add or remove metal. Going more than two sizes either way can change the shape of a ring, so we'll tell you before we start. Resizing usually takes about a week.

Buying it as a surprise? Borrow a ring they wear on the same finger and bring it in, and we'll measure it.
