Ring Size Guide

How to Find Your Ring Size

For the most accurate result, measure your finger at the end of the day when your hands are at a normal temperature. Cold fingers can measure smaller, while heat and swelling can make them measure larger.

Method 1: Measure an Existing Ring

  1. Choose a ring that already fits the intended finger.
  2. Measure the inside diameter across the widest point in millimeters.
  3. Match the measurement to the chart below.

Method 2: Measure Your Finger

  1. Wrap a strip of paper or non-stretch string around the base of the finger.
  2. Mark where the ends meet.
  3. Measure the length in millimeters. This is the finger circumference.
  4. Compare the result with the chart.

Helpful Tips

  • Measure the exact finger where the ring will be worn.
  • If the knuckle is wider than the base of the finger, measure both and choose a size between them.
  • For a wide band, consider choosing approximately half a size larger.
  • If you are between sizes, choose the larger size.
  • For an important purchase, a local jeweler can provide the most reliable measurement.
