Ring Size Guide
You can find your ring size by measuring the inner diameter of a ring you already own, or by measuring your finger circumference.

Method 1 — Using a ring
Place a well-fitting ring on a ruler and measure the inner diameter in millimeters.
Compare the measurement with the size chart.

Method 2 — Measuring your finger
Wrap a thin strip of paper or a soft measuring tape around your finger.
Mark where it overlaps and measure the length on a ruler.
This measurement in millimeters corresponds to your EU ring size.
Make sure the paper also fits over your knuckle.

Tips
• Measure at the end of the day when your fingers are naturally slightly larger.
• Hands can swell with temperature — if you’re between sizes, choose the larger one.
• Sizes may differ between your left and right hand; your dominant hand is often slightly bigger.
