Ring Size Guide

Rings can be the most sentimental of jewellery pieces. Whether buying yourself a new stack ring or thinking of popping the question, getting the right fit is of utmost importance whatever the scenario. We appreciate when buying online getting the ring size right is not always straightforward, so to make it a little easier you can download our free ring sizer.

How to Measure Your Ring Size at Home

Finding your perfect ring size is simple with a few quick steps:

  1. Download our free printable ring sizer. Print the guide at 100% scale for accurate measurement.

  2. Cut out the ring sizer strip and wrap it comfortably around the base of your finger.

  3. Note where the strip overlaps to find your measurement in millimetres.

  4. Compare your result with our ring size chart in letters and numbers below to find your ideal size.

  5. If you already have a ring that fits well, measure its inside diameter and use our international conversion chart to check your UK, US, or EU size.

Tip: Measure your finger at the end of the day when it’s warm — fingers can vary slightly in size throughout the day.
