Ring size

First you fall for that stunning appearance. The unique sparkle and vibrant colours. You find yourself instantly falling in love, with a ring! But then comes the size. The right ring size is an important issue with vintage jewellery; after all, there is only one of each ring. Fortunately, determining the right ring size is quite simple and easy to do yourself at home. Based on the ways below, you'll know your ring size in seconds.

Measuring using a matching ring

  1. Take a ruler and a ring that fits snugly around the desired finger.
  2. Measure the diameter of the inside of the ring in millimetres.
  3. The measured size in millimetres is your ring size.

Example: If the diameter of the inside of the ring is 16 millimetres, then your ring size is 16.

Measuring the circumference of your finger

  1. Take a strip of paper or string, a ruler and a pen.
  2. Wrap the strip of paper or string tightly around your finger.
  3. Make a mark with the pen where the paper or string touches.
  4. Using the ruler, measure the length of the paper or string to the line in millimetres.
  5. Use the table below to determine which ring size belongs to the measured circumference of your finger.

Example: If the measured circumference of your ring finger is 50 millimetres, your ring size is 16.

Measuring with your smartphone
