The first step in finding your dream ring is finding your ring size. Designed to accurately measure the size of your finger, this plastic tool should be looped around the finger so that the end can be pulled until the ring is snug. The correct ring size should also be able to move over your knuckle, but it is normal for the ring to feel tight when doing so. Look for the little black arrow to determine the ring size. Our size finder will show full, half and quarter sizes, and ship to you within 48 hours.

Your ring should feel snug, but comfortable at the base of your finger. It is normal for there to be some difficulty when getting the ring over your knuckle.

The climate and temperature affects sizing. Measure when your hands are at room temperature for the best accuracy.

Size the exact finger for the ring. Hands and fingers are not identical.

For the most accurate size, measure your ring size multiple times and on different days.

If the Ring is a Surprise

1. Ask your friends or family if they know your partner’s ring size.
