Ring Sizes

How to measure your ring size

1. Select a ring you already own that properly fits the intended finger.

2. Measure the INSIDE diameter of the ring.

3. Match the measurement to the conversion chart. If the ring falls between two sizes, we advise you to order the larger of the 2 sizes.

Please note:

Rings with a particularly thick band will feel tighter than a thin band. In these cases, we recommend choosing a full size larger than your normal ring size.

Tips

Your ring should fit your finger comfortably– snug enough so it won’t fall off, but loose enough to slide over your knuckle. As your finger size can change throughout the day, it’s best to measure at the end of the day when your fingers are at their largest. Measuring when your hands are cold can sometimes mean your fingers will be at least half a size smaller.

*KWJewels uses the French/Japanese method of ring sizing but can convert any measurement given to correctly size your choice of ring.
