Ring Size Chart

Ring Size Guide
At More Than Gems, we use the U.S. Ring Sizing System. Below is a ring size comparison chart for different systems.

How To Determine Ring Size
Use a ring that fits you to determine your approximate ring size. Simply place your ring over the nearest size circle on the monitor at 1280 x 1024 resolution OR just print the size chart at 100%. Then place your ring over the nearest circle. The inner edge of the ring should align with the outer edge of the circle. If your ring appears to fit between two sizes, buy the larger size.

Please Note: More Than Gems Ring Size Guide is based on the US Ring Sizing System and serves as only an estimated ring size. Weather, time of day, weight, diet and many other factors can significantly effect an individual’s ring size.
