Three Ways to Find Your Size at Home
01
Use a Ring You Already Own (Most Accurate)
If you have a ring that fits your ring finger comfortably, this is the most accurate method. Download and print our ring size chart (linked below). Place your existing ring on the chart and match the inner circle to your ring’s interior diameter. The matching circle gives you your US ring size. This method works best if the ring you’re measuring fits the same finger on the same hand as the new ring will be worn.
02
String or Paper Strip Method
Cut a thin strip of paper or string. Wrap it around the base of your ring finger — snugly, but not tight. Mark the point where it overlaps with a pen. Measure the length of the strip in millimetres. Use the circumference column in our size chart below to find your US ring size. Measure your dominant hand’s ring finger — rings are typically worn on the left hand, but right-hand measurement is fine for the purpose of sizing.

Important Sizing Tips
Measure at the Right Time
Fingers change size throughout the day. They are smallest in the morning and in cold weather — and largest in the evening and in warm conditions. For the most accurate measurement, measure in the evening when your fingers are at their fullest size.
Account for Band Width
Wider bands fit more snugly on the finger than narrow ones. If you are choosing a band wider than 6mm, we recommend sizing up by half a size for comfort. Our team can advise on this during a consultation.
Buying as a Surprise?
If you’re purchasing a ring as a surprise gift, order in what you believe to be the most likely size — or choose US 6 (the most common women’s size). Our complimentary resize within 60 days means there is no pressure to get it exactly right the first time.
