Measure your finger
  1. Use a soft tape measure or string to measure your finger.
  2. Wrap the measuring tape or string around the finger where you want to wear your ring. If you plan to wear multiple rings together, measure your finger at the exact spot where the ring will sit. If you are using a string, mark the point where the ends meet.
  3. Then lay the string out on a flat surface and measure the length between the marks with a ruler (in millimeters). Compare this measurement with our size chart to determine your ring size.Determine your ring size
