How to Measure Ring Size
For precise sizing, we recommend a ring mandrel—a tapered rod marked with sizes—to measure an existing ring worn on the same finger. Alternatively, a finger-sizing tool, typically a set of graduated rings, can be used directly on the finger to determine the ideal size.

1. Cut a piece of string, floss, thin paper, or yarn at least 3 inches in length.
2. Gently wrap it around the base of your finger for a comfortable yet snug fit.
3. Mark where the end of the string overlaps.
4. Lay the string flat and measure from the end to your mark using a rule.
