Ring Size Guide
How to Find Your Ring Size
Getting the right ring size ensures a comfortable, secure fit. Use one of the methods below to find yours.
Method 1: Measure an Existing Ring
If you already have a ring that fits the intended finger, measure its inner diameter in millimeters and use the chart below.
Method 2: Measure Your Finger
- Wrap a thin strip of paper or a piece of string around the base of the intended finger.
- Mark where the paper/string overlaps to form a complete circle.
- Measure the length in millimeters — this is your finger circumference.
- Find your size in the chart below.
Tip: Measure in the evening when fingers are at their largest. Fingers swell slightly in heat and shrink in cold.
