Ring Sizes

The easiest and quickest way to find your ring size is to measure the inside diameter of a ring that fits your finger and compare it to the numbers of the chart below, pick the number closest to your measurements.



Don't have a ring to measure?

Another easy way to find your perfect ring size is to measure the circumference of your finger with some paper and a ruler:

  1. Cut out a strip of paper 12 cm long and 0.5 cm wide and make sure your finger is at room temperature.

  2. Wrap strip of paper around the base of your finger. It has to fit snug, but not too tight.
  3. Mark the point on the string/paper where it overlaps forming a circle. 

  4. Measure the part that was wrapped around the finger until the point you've marked. This is the circumference of your finger. Compare it in the table chart below to find the perfect size.
