HOW TO MEASURE A RING YOU ALREADY HAVE

  1. Choose a ring that fits the finger you want to wear the new one on and lay it flat.
  2. With a ruler, measure straight across the inside of the ring, from one inner edge to the other, through the centre.
  3. Write down the result in millimetres (mm).
  4. Find the closest inner diameter in the chart above.

Tip: measure only the inside of the ring, never the outer edge.

HOW TO MEASURE YOUR FINGER

  1. Take a thin strip of paper or a piece of string.
  2. Wrap it around the base of your finger, snug but not tight.
  3. Mark the point where the two ends meet.
  4. Lay it flat and measure up to the mark in millimetres (mm).
  5. Find the closest circumference in the chart above.

Tip: fingers are slightly larger in the evening and smaller when cold, so measure at the end of the day at room temperature.
