Ring Size Guide

Find your best fit with three simple measuring methods and our international ring-size conversion chart.

1. Three Measuring Methods

Paper or String Method

  1. Wrap a thin strip of paper or non-stretch string comfortably around the base of your finger.
  2. Mark where the ends overlap, then measure the length in millimetres. This is your finger circumference.
  3. Match the measurement to the chart below.

Tip: Measure at your usual wearing time. Fingers are often slightly larger in the evening.

Existing Ring Method

Measure the inside diameter of a ring that already fits well, in millimetres, then match it to the chart.

Printable Ring Sizer

A correctly scaled printable ring sizer can be used as a second check. Always confirm the printed scale before measuring.

Circumference is approximately diameter × 3.1416. The chart is a general reference; fit can vary by design.

3. Choosing the Best Fit

  • Prominent knuckle: choose a size that slides over the knuckle without spinning excessively.
  • Wide bands: a half size larger may feel more comfortable.
  • Temperature: avoid measuring when your hands are unusually hot or cold.
  • Between sizes: choose the larger size unless the product page advises otherwise.
