Size Guide

How to Measure Your Ring Size
Two easy methods — use whichever works for you.
Method 1 — String or Paper Strip
- Cut a thin strip of paper or use a piece of string about 6 inches long.
- Wrap it snugly around the base of the finger you want to wear the ring on. It should feel comfortable — not too tight, not loose.
- Mark or pinch where the paper/string meets, then measure that length in millimeters against a ruler.
- Match your measurement to the Circumference column in the chart below.
Method 2 — Measure an Existing Ring
- Find a ring that already fits the correct finger perfectly.
- Use a ruler to measure the inside diameter of the ring in millimeters (straight across the inside of the band).
- Match your measurement to the Diameter column in the chart below.
Tip: Fingers swell slightly in the heat and shrink in the cold. Measure in the afternoon when your fingers are at their natural size. If you're between two sizes, size up.
