Our rings are made in whole and half sizes from 4 to 13. Use the chart below to match a ring you already wear, or measure your finger directly.
Find your size from a ring you own
Lay a ring that already fits on a ruler and measure straight across the inside, from edge to edge. Match that measurement to the inside diameter column.
Measure your finger
Wrap a strip of paper around the base of your finger, mark where it overlaps, then lay it flat against a ruler. That length is your inside circumference.
Fingers change through the day and with the weather. Measure when your hands are warm and at their normal size, and take the larger reading if you are between two sizes. A wide band tends to feel tighter than a narrow one in the same size.
