Rings Sizing Guide

Find your perfect ring size at home in a few minutes, then shop with confidence.

How to measure your ring size

All you need is a strip of paper, a pen and a ruler.

Step 1
Pick the finger you’ll be adding a ring to.
Step 2
Cut a strip of paper—thin enough to lie flat against your skin.
Step 3
Place it at the base of the finger and wrap it around the spot where you’d like your ring to sit.
Step 4
Pull it snug to make sure you get the best fit.
Step 5
Mark the point where the paper meets.
Step 6
Measure the length using a ruler, in millimeters.
Step 7
Repeat as necessary. It’s always best to double (or triple) check.
Step 8
Then, match your measurement to the chart below. If you fall between ring sizes, we suggest measuring up for comfort.

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.

Thin bands

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.

Thick bands

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.

Chain rings

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

When should I measure my ring size?

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.

Are all of my fingers the same ring size?

Finger sizing varies—even for the same finger on different hands. For the best fit, measure each individually.

What if I’m between sizes?

We don’t offer half sizes, so we recommend sizing up. A little extra room is always more comfortable.
