Ring Size Guide

Find Your Perfect Fit

A well-fitted ring ensures comfort, beauty and everyday wearability. Use our at-home guide below to determine your correct ring size.

Option 1

Measure an Existing Ring Using a Ruler

  1. Select a ring that fits the intended finger comfortably.
  2. Place the ring on a flat surface.
  3. Align the inside edge of the ring with the 0 cm mark of a ruler.
  4. Measure the inner diameter in millimetres (mm).
  5. Compare your measurement with the conversion chart below to find your ring size.

Tip: Measure across the widest point of the inner circle for best accuracy. Example: If the inner diameter of your ring measures 17.3 mm, your UK size is N, US size is 7, and EU size is 54 mm.

Option 2

Measure Your Finger

  1. Cut a thin strip of paper.
  2. Wrap it comfortably around the base of your finger.
  3. Mark where the paper overlaps.
  4. Measure the length in millimetres (mm).
  5. Refer to the conversion chart below to determine your correct ring size.

  • If you require assistance or are ordering a surprise gift, our jewellery specialists will be pleased to guide you toward the perfect fit.
