It’s best to measure your ring size when your fingers are at their largest, which is usually at the end of the day. Determine the circumference of your finger using a flexible tape measure and the chart above. To do this, wrap the tape measure around the base of your finger and make sure it can slide easily on and off over your knuckle. If you’re between two sizes, we suggest ordering the larger size and making it smaller. For more sizing information, please visit our FAQ page.
