Use String to Measure her Finger

  1. Cut a piece of string and wrap it around her finger (make sure it’s not too tight).
  2. Then cut or mark the string at the exact measurement.
  3. Measure the string with a millimeter ruler.
    This measurement is the inside diameter of the ring.
  4. Use this conversion chart to convert the mm length to her ring size.
    Note: Please note this is a self-help tool to be used as a general guide. The most accurate way to figure out her ring size is to use the ring size tool or have her finger measured at a jeweler.
