Size Charts
Three ways to find your ring size, and how to read the chart if you are between two.
Our ring size chart
Whether you are measuring for yourself or for someone else, start here. If you find yourself between two sizes, choose the larger one for a more comfortable fit.

The most common sizes for women’s ring fingers are 6 and 7. Sizes 2 to 4 are the usual pinkie range.
Measure a ring you already own
This is the most reliable method. Inside diameter is the measurement that actually matters, so measure straight across the inside of a ring that already fits the right finger, then match it against the Inner Diameter column above.
Measure your finger at home
No ring sizer? A thin piece of string, dental floss or a strip of paper will do.
- Wrap it around the finger you intend to wear the ring on.
- Mark the point where it overlaps.
- Measure that length against a ruler in millimetres.
- Match it to the Finger Circumference column above.
A few things worth knowing
- Measure when your fingers are at their natural size. Cold weather contracts them, while heat and exercise make them expand.
- If you have larger knuckles, size up so the ring passes over comfortably.
- Sizes differ between your left and right hands, and can shift with the seasons or with your health.
- A well-fitting ring slides on easily and takes a little effort to remove.
