Ring Size Chart

Here's an easy way to measure your ring size: take a piece non-elastic string, a ribbon, or a small strip of paper and tightly wrap it around the bottom portion of the finger you want to size. After marking where the ends meet, measure the length with a ruler or tape measure (inches or millimeters) to the closest 1/8". Use the chart below to find your perfect fit!
