Ring Size Guide

Getting the right size first time means your ring arrives ready to wear. Use one of the two methods below, then find your size in the chart. If you fall between two sizes, choose the larger one.

Quick tip: Australian sizes use letters (the same system as the UK). US sizes use numbers. Every ring on our store shows both, for example US 6 / AU L½.

Method 1: Measure a ring that already fits

Inside diameterMeasure inside edge to inside edge
  1. Choose a ring that fits the finger you're buying for.
  2. Lay it flat on a ruler with millimetre markings.
  3. Measure straight across the inside of the ring, from inside edge to inside edge. Don't include the metal.
  4. Find that number in the Inside diameter column below.

Method 2: Measure your finger with paper

1. Wrap and mark2. Lay flat and measureto the mark, in mm
  1. Cut a thin strip of paper about 1 cm wide.
  2. Wrap it around the base of your finger. It should be snug but still slide over your knuckle.
  3. Mark where the paper overlaps with a pen.
  4. Lay the strip flat on a ruler and measure from the end to your mark, in millimetres.
  5. Find that number in the Circumference column below.

Most of our rings come in US 4 to 9. Some pieces also come in 9.5 and 10. Measurements are a guide and may vary slightly.

Tips for an accurate fit

  • Measure at the end of the day. Fingers are slightly bigger in the evening and when you're warm.
  • Measure 2 or 3 times to make sure you get the same number.
  • Wide bands (over 6 mm) fit tighter. Go up half a size.
  • Your dominant hand is usually a little larger.
  • Buying a surprise? Borrow a ring they already wear on the right finger and use Method 1.
  • Still unsure? Any local jeweller can size your finger for free in a few minutes. You can also contact us and we'll help.
