Choose Your Measuring Method
There are two simple ways to find your ring size. Choose the method that works best for you.
Measure a Ring You Already Own
Use a ring that fits comfortably on the intended finger. Measure the inside diameter across the widest inner circle point and compare it with our chart.
Measure Your Finger
Use a thin strip of paper or a non-stretch thread to measure around the base of your finger, then compare the marked measurement with our size chart.

Tips for a Better Fit
Measure More Than Once
Repeat the measurement 2–3 times to ensure your result is completely consistent.
Normal Temperature
Fingers contract in cold and swell in heat. Measure when your hands are at normal room temperature.
Measure At The End Of The Day
Fingers are often slightly larger in the evening than early in the morning.
Consider Ring Width
Wider bands (over 6mm) have a snugger fit. Consider choosing a half-size larger for wide designs.
Between Sizes?
If your measurement falls between two standard sizes, we recommend opting for the larger size.
