Finding your perfect fit should feel as effortless as putting on your favorite piece of jewelry. Use the steps below to discover your ideal ring size — from the comfort of home.
Option 1: Measure With a Ring You Already Own
Choose a ring that fits the exact finger you plan to wear your new piece on
Measure the inside diameter with a millimeter ruler
Match your measurement to our size chart below
Option 2: Paper Measuring Strip (No Ring Needed)All you need is:
A thin strip of paper or string
A pen
A ruler
Steps:
Wrap the paper around the widest part of your finger (usually near the base or around the knuckle)
Mark where the paper overlaps
Measure the length in millimeters
Match the measurement to the “Inside Circumference” column in our chart
Pro Tip:
Measure at the end of the day — fingers can be smaller in the morning and shrink in cold weather.

Fit TipsIf you’re between sizes, we recommend going up one half-size
Knuckles slightly larger than the base? Choose a size that slides comfortably over the knuckle without feeling loose
Stacking rings may require ½ size up
Temperature, pregnancy, and sodium intake can all affect finger size — wild, right?
