We advise that you measure the size of your finger rather than the size of your ring.
Wrap a length of string or ribbon around the base of your finger. To ensure the ring fits comfortably, we suggest measuring your knuckle as well. Select a size that will slide on and off your finger easily.
With a pen, mark the point on the string where the ends meet.
Measure the string in millimetres with a ruler.
Choose the closest measurement to the chart below to identify your ring size.
