Find your ring size

Three ways to get there. If you already own a ring that fits the right finger, the on-screen gauge is the most accurate.

Step 1 — Calibrate your screen

Hold any credit, debit or ID card against the screen and drag until the widths line up exactly. Every card in the world is the same size, so this makes the measurements below true to life.

85.60 mm
Step 2 — Match your ring

Rest the ring flat on the screen and resize the circle until it sits just inside the band, touching but not hidden.

Measure warm

Fingers shrink in the cold. Measure at the end of the day, at room temperature, for the size you will actually wear.

Wide bands run tight

Anything above 6 mm wide sits closer to the skin. Go up half a size for comfort.

Between two sizes

Choose the larger one. A ring has to pass the knuckle, and a slightly loose band can be sized down more easily than a tight one can be opened.

Still unsure

Email your measurements and we will confirm before the piece goes into production. Every Luzora ring is made to order.
