Ring Size Guide

Find your perfect fit with our easy ring size guide. Whether you’re measuring a favourite ring or your finger, we’ll show you how to get it right.

Measure my Own Ring

The quickest way to find your size if you already have a ring that fits the right finger.

1. Choose a ring that fits the finger you're sizing.

2. Measure the inside diameter of the ring in millimetres (be sure your ruler starts at 0mm).

3. Match the measurement to our size chart to find your ring size. The most common women's ring sizes are US 6 and US 7.

✨ Between sizes? Always size up for comfort.

Measure My Finger

No ring on hand? No problem. A piece of string will do the trick.

1. Wrap a piece of string snugly around the finger you want to measure.

2. Mark the spot where the ends meet.
Lay the string flat and measure its length in millimetres.

3. Use the "Circumference (mm)" column in our size chart to find your ring size. Most women's ring fingers measure around a size 6 or 7.

✨ Between sizes? Go for the larger one.
