We'll send you a complimentary, unisex, and reusable ring sizer by mail, allowing you to accurately determine the most comfortable size for you.
Simply wrap our sizer around the finger you wish to measure, adjusting it to the size that feels just right. The ideal size should be snug enough to stay in place but loose enough to slide over the knuckle without excessive resistance.
