Ring size table

There are two ways to determine your ring size:

  • The first method is to take a suitable ring and measure the inner diameter of the ring with a ruler with a millimeter scale. Then, read your ring size from the chart.
  • The second method for determining your ring size is to use a string to measure the circumference of your finger at the point where you plan to wear the ring. Alternatively, you can wrap a strip of paper tightly around your knuckle, mark the location, and then measure the length of the strip to the mark (in mm).

Please note the following:

  • The fingers of the left and right hand are usually different thicknesses, so you should measure exactly the finger on which you want to wear the ring.
  • Your ring size changes throughout the day. Fingers are usually thicker in the evening than in the morning.
  • Ring sizes also change throughout your life, so avoid relying on a size measured long ago.
  • Fingers are usually thicker in summer than in winter. The higher the temperature, the thicker the fingers.

Conversion formula and table (diameter - circumference)

Ring / finger circumference = inner diameter x 3.14

Inner diameter = finger circumference x 0.318
