Two minutes, at home
Getting your ring size right the first time means your new ring fits comfortably from the moment it arrives. Here are two simple ways to measure at home.
How to measure
Measure your finger
Using a strip of paper or string
Use a thin strip of paper or a piece of string and wrap it around the base of your finger. Take a pen and mark the spot where the ends meet. Lay the paper down on a ruler and measure the length in millimeters. Use the chart below to find your size.
Getting it right
Tips for properly measuring
Wrap the strip below the joint of your finger, close to your knuckle. Measure at the end of the day, when fingers tend to be slightly more swollen. If you find that your knuckle is noticeably larger than the base of your finger, choose a size that falls in between the two measurements.

A note on fit
Fingers can be slightly larger in warm weather and smaller in the cold, so aim for a comfortable, room-temperature measurement. If you're between two sizes, we generally recommend sizing up for the most comfortable fit, especially for wider band styles.
Common questions
Good to know
What if I'm not sure of the size after measuring?
Measure two or three times on different days and take the most common result. If you're between sizes, sizing up is usually the more comfortable choice.
Do you offer resizing after purchase?
Reach out to our team after your order arrives and we'll help you with resizing options for your specific piece.
Does finger size change over time?
Yes, it's normal for finger size to shift slightly with age, weather, and other factors. If a ring you've worn for years suddenly feels different, that's usually why.
Should I measure my dominant or non-dominant hand?
Measure the exact hand and finger the ring is intended for, since size can vary slightly between hands.
