How To Measure
Measuring at Home
All you need is a piece of string or a thin strip of paper, a pen, and a ruler. Follow these three simple steps to determine your ring size with confidence.
Measure your finger at the end of the day when it is at its largest. Avoid measuring when your hands are cold, as fingers tend to be smaller in cooler temperatures.
The Foundation
Wrap a piece of string or a thin strip of paper snugly around the base of your finger. Make sure the material sits comfortably and is not too tight or too loose.
Mark the Intersection
Using a pen, mark the exact point where the string or paper overlaps to form a complete circle. Be precise with your marking for the most accurate result.
Record & Compare
Lay the string or paper flat and measure the length in millimeters from the starting end to the mark. Compare your measurement to our international conversion chart below to find your ring size.

Good to Know
Sizing Tips
Wide Bands
Wider bands fit more snugly than narrow ones. If you are choosing a band wider than 6mm, we recommend going up a half size for a comfortable fit throughout the day.
Atmospheric Change
Your fingers change size with the weather. Cold temperatures cause them to shrink, while heat and humidity cause them to swell. Keep this in mind when measuring.
Morning vs. Night
Fingers tend to be slightly smaller in the morning and larger in the evening. For the most accurate size, measure at multiple times throughout the day and use the average.
