Fit Tips
Measure your finger toward the end of the day, when fingers are at their largest. Cold fingers will measure smaller than they actually are. If you're sizing for a finger with a wider knuckle, choose a size that slides over the knuckle comfortably without forcing it.
How to measure for rings
Method 1—Measure a ring you already own
Measure straight across the inside of the ring at its widest point. Match that measurement to the Interior Diameter column and read across to the US size. Measure the inside of the band only, not the outside.
Method 2—Measure your finger
Wrap a paper strip around the base of the finger, mark where it overlaps and measure the marked length in millimetres. Match that measurement to the Interior Circumference column and read across to the US size. A ring fits when its interior circumference equals the circumference of the finger, so the two measurements have the same value.
