Ring Size Guide
Not sure of your ring size? Use the chart below to convert a measurement, or stop by the showroom and our jewelers will size your finger in minutes, free of charge. Most rings we sell can be resized, and we cover the first resizing on any engagement ring purchased from us.
Find your size at home
- Use a ring that already fits. Lay it on a ruler and measure the inside diameter in millimeters, edge to edge. Match it in the chart.
- Or measure your finger. Wrap a thin strip of paper or string snugly around the base of the finger, mark where it overlaps, then measure the length in millimeters. That is the circumference.
- Measure at the end of the day when fingers are at their largest, and avoid measuring when your hands are cold.
- Wide bands fit tighter. For bands 6mm or wider, go up a half size.
- Knuckles matter. If your knuckle is much larger than the base of your finger, choose a size between the two measurements.

Buying a surprise engagement ring?
Borrow a ring she wears on her ring finger (left hand, fourth finger) and trace the inside on paper, or bring it to us. If you can't, ask a friend, or go with the average: a US 6 to 6.5 for women and a 10 for men. We'll resize it for free after the proposal.
