Finding your ring size

You don’t need special tools to find your ring size—just a strip of paper and a moment of focus.

  1. Cut a thin strip of paper about 5mm wide.
  2. Wrap it snugly around your finger, where you’d like the ring to sit. Make sure it’s not too tight; it should slide over the knuckle comfortably.
  3. Mark the point where the paper overlaps.
  4. Measure the length from the edge to your mark using a millimeter ruler.
  5. Use the chart below to convert this measurement into your ring size. If you’re between sizes, we recommend sizing up for comfort.
