Ring Sizing

Determining your ring size is easy but care must be taken to ensure accuracy. Here are a few ways:

Option 1: Stop by a jewelry store and ask them to size your finger. This is the most accurate method. Please note - when using a ring mandrel for sizing, we use the leading edge for bands that are flat inside, and the center for comfort fit bands.

Option 2: Grab a ring that fits your finger and carefully measure the inside diameter with a ruler in inches or millimeters.

Option 3: Another way is to wrap a strip of paper around your finger and mark where the ends overlap, then measure the length to determine the circumference. Tape the strip on the marks to form a ring and make sure it can pass over you knuckle.

To determine your size, find the matching measurement in the ring size chart below. If your measurement falls between two sizes, we suggest that you select the larger size. For rings with a wide band, we also recommend ordering a quarter to a half size larger than usual.
