Ring Size Guide PDP
Measure your finger
-
Wrap a piece of string, or a thin strip of paper, around the base of the finger. Snug, not tight.
-
Mark the point where the end overlaps.
-
Lay it flat against a ruler and read the length. That is the inside circumference. The chart below is in millimeters, so 5.4 cm on a metric ruler means 54 mm.
Or measure a ring that already fits
Place the ring on a ruler and measure straight across the inside, edge to edge. Match that to the inside diameter column. Use a ring worn on the same finger — sizes differ from hand to hand.

Before you decide
- Measure late in the day. Fingers are smallest in the morning and in the cold, and a reading taken then will come out a size small.
- Check the knuckle. The ring has to pass over it. If the knuckle is much larger than the base of the finger, size to clear the knuckle.
- Wide bands fit closer. For a band wider than about 6 mm, allow a quarter to half size up.
- Between two sizes? Take the larger one. A slightly loose ring can be adjusted; one that will not pass the knuckle cannot be worn.
