Ring Size Guide

Find your fit.

Every Zurae ring is made to order in your size, measured around the inside of the ring: 47–62 mm for our engagement rings and 56–70 mm for men's rings. Two minutes with a ruler is all it takes to find yours, and the chart below converts from US, Hong Kong and Japanese sizes too.

01 · Measure

Two easy ways at home

Option A

Use a ring you already own

Most accurate

Choose a ring that fits the finger you're buying for.
Lay it flat on a ruler.
Measure the inside diameter, edge to edge, in millimetres.

Option B

Use a strip of paper or string

No ring needed

Wrap it snugly around the base of your finger.
Mark where the ends meet, then check it still slides over your knuckle.
Lay it flat and measure the length, the circumference, in millimetres.

Zurae sizes are the inside circumference of the ring in millimetres, the same as EU sizing. Already know your US or Hong Kong size? Find it in the chart and order the size on the left.

04 · Tips

For the perfect fit

Measure at the end of the day. Fingers are slightly larger in the evening and when warm, and smaller in the cold.
Between two sizes? Choose the larger one.
Mind the knuckle. Your ring must slide over it, so if your knuckle is wider than the base of your finger, size for the knuckle.
Wide or eternity bands sit more snugly than a slim band. Consider going up half a size, as full eternity bands can't easily be resized.
Buying as a surprise? Borrow a ring they wear on that finger and use Option A.
