Get a strip of paper. Wrap the strip of paper around the finger you desire to wear the ring. To ensure the ring fits comfortably, we suggest measuring your knuckle as well. We strongly recommend selecting a size that will slide on and off your finger easily. With a pen, mark the point at which two ends meet. Measure the paper from mark to mark to find your ring circumference with the help of a ruler (mm). Then use the Ring Size Guide to choose the closest measurement to identify your ring size. 

As finger size can change depending on the time of the day and the weather, for the most accurate measurement, do avoid measuring your fingers when they are cold or wet when they will be at their smallest.
