WHAT YOU SHOULD KNOW
Finding your ring fit? Rings are designed to feel comfortable from the start, with subtle differences across styles. Here’s what to expect from each fit.
Lightweight and easy to wear. Thin bands sit close to the finger with a barely-there feel. They’re comfortable for everyday wear and ideal for stacking, with a little natural movement when worn together.
Thicker bands take up more space on the finger, which we account for in the design, so they still feel comfortable. Stick with your usual size—but note that stacked rings will fit and feel different than a single thin band.
Flexible by design. Chain bands move with your finger for an easy, relaxed feel. They should sit comfortably without feeling tight, offering a bit more give than a solid band.
FAQ
Measure at the end of the day, when your fingers are naturally a little fuller. Make sure your hands are warm, as cold temperatures can shrink fingers by up to half a size. Alcohol, salt, and hormonal changes can also cause temporary swelling, so try not to measure after cocktails or salty snacks.
Finger sizing varies—even for the same finger on different hands. For the best fit, measure each individually.
We don’t offer half sizes, so we recommend sizing up. A little extra room is always more comfortable.
