Ring Size Guide
Selecting the correct ring size is essential for comfort and long-term wear. Use the methods below to determine your size accurately at home.
How to Measure Your Ring Size
Measure Your Finger
Wrap a thin strip of paper or string comfortably around the base of the finger. Mark where it overlaps, then measure the length in millimeters. Use this measurement to find your size in the chart below.
Measure an Existing Ring
Measure the inside diameter of a ring that fits the intended finger, straight across in millimeters, and match it to the chart.
Professional Sizing Recommendations
- Measure at room temperature, ideally at the end of the day
- Avoid measuring when hands are cold or swollen
- If your measurement falls between sizes, select the larger size
- Wider bands may require a slightly larger size for comfort
