Ring Size Guide

Find your fit

A ring should sit comfortably at the base of your finger and slide over your knuckle with a little resistance. Choose one of the methods below to find your size.

  • Measure when your hands are at a comfortable temperature; heat and cold can affect sizing.
  • Fingers can differ between hands, so check the exact finger.
  • Wider bands and stacked rings may feel tighter.
  • Paper or string can give a rough estimate, but confirm with a ring sizer or jeweller if you’re unsure.


Check your size at home with our ring sizer. Follow the instructions supplied and measure the finger you intend to wear the ring on. Check the fit more than once before choosing your size.

Shop the Ring Sizer

Choose a ring that fits the intended finger comfortably.

  1. Measure across the centre of its opening in millimetres, from inside edge to inside edge.
  2. Match the measurement to the inside diameter column in our size chart.

A ring with a similar band width to the one you’re considering will give you a better comparison.

A string or narrow strip of paper can give you an initial estimate, although it is less reliable than a ring sizer or professional fitting. String can stretch or pull too tightly.

To measure with string or paper:

  1. Wrap a string or  narrow strip paper around the base of your chosen finger without pulling it tight.
  2. Mark where the ends meet.
  3. Lay it flat and measure the length to the mark in millimetres.
  4. Compare the result with the inside circumference column of our chart.

This method does not reliably show how a rigid ring will pass over your knuckle. Confirm the result with a ring sizer or jeweller before ordering if you’re unsure.
