How to measure your ring size
To determine your size, we strongly advise that you measure the size of your finger rather than the size of your ring.1. Using a length of string or ribbon, wrap it around the base of your finger. To ensure the ring fits comfortably, we suggest measuring your knuckle as well. We recommend selecting a size that will slide on and off your finger easily.
2. With a pen, mark the point on the string where the ends meet.
3. Measure the string in millimeters with a ruler.
4. Choose the closest measurement to the chart below to identify your ring size.
