Ring sizing guide
Get the size right before you order. Stainless and titanium often feel a little snugger than softer metals. If you are between sizes, the larger size is usually more comfortable.
Wrong size after it arrives? See Fit or Credit — store credit or a size exchange, with you paying the return label. We do not send free prepaid return labels.
How to measure
- Paper strip. Wrap a thin strip of paper around the intended finger (the one you will wear the ring on). Mark where it overlaps. Measure that length in millimeters. Match it to the inside circumference in the chart below.
- A ring that already fits. Measure the inside diameter in millimeters (straight across the inside of the ring). Match it to the chart.
Measure at the end of the day when fingers are a bit larger. If your knuckle is bigger than the base of the finger, size for the knuckle so the ring can pass, then sit.
