Ring Size Chart

Every ring is made to your exact size. Here's how to find it.

How to Find Your Ring Size at Home

  1. Cut a thin strip of paper or use a piece of non-stretchy string.

  2. Wrap it snugly around the base of your finger (where the ring will sit). It should be comfortable — not too tight, not too loose.

  3. Mark where the strip overlaps, then lay it flat and measure the length in millimeters.

  4. Match that measurement to the Circumference column in the table above. Pick the closest size.

  5. If you're between sizes, go up to the next size — it's easier to resize down than up.

Fingers swell slightly in warm weather and shrink in cold. Measure at room temperature, ideally in the evening when your fingers are at their largest. For a more precise measurement, visit any local jeweller — most will size your finger for free.
