Measure an Existing Ring
Select a ring that already fits the finger you'd like to wear your new piece on.
Place the ring on a ruler and measure the internal diameter in millimetres (the distance across the inside of the ring).
Match your measurement to the chart below. If you fall between two sizes, we recommend choosing the larger size.
Measure Your Finger
Cut a thin strip of paper or use a flexible measuring tape.
Wrap it snugly around the base of the finger where you want the ring to sit — it should be snug but comfortable enough to slide over your knuckle.
Mark where the paper meets, then measure that length in millimetres — this is your finger circumference. Enter it into our calculator below.

Sizing Tips
Time & Temperature
Fingers expand in warmth and shrink in cold. Measure at the end of the day, at room temperature, for the most accurate fit.
Wide Bands
Wide band rings (5mm+) feel tighter than narrow ones. If ordering a wide band, we recommend sizing up by half a size for comfort.
