3 ways to find your ring size

Methode 1:

Use string and ribbon to measure your finger

  1. Take a piece of string or ribbon and wrap it around your finger.
  2. Mark with a pen where the string/ribbon overlaps.
  3. Stretch the string/ribbon and measure with a ruler.
  4. The length of the string is your ring size. Eg. if your finger measures 52mm, your ring size is 52.
  5. Alternatively, you can use a measuring tape or look at the ring size table.
Methode 2:

Measure a ring you already have

  1. Take an existing ring and measure the inside diameter with a caliper.
  2. This number must be multiplied by Pi. Eg. if the diameter is 16.5mm, the calculation is: 16.51mm x 3.14159265359 = 51.9. Your ring size is 52.
Methode 3:

Print out the ring size chart

Find a ring that you already have and that fits your finger.Download and print the ring size chart and place your ring on the circles. Remember to print in actual size (Scale 100%). Possibly. Double check that the measurements fit the numbers on the paper.
The diameter of the circle should match the inside circumference of your ring.
