How to find the right ring size?

1. Use a ring you already have that fits the corresponding finger perfectly.

You can measure the diameter with a ruler or tape measure and then multiply the value by 3.14. The result will correspond to the size of your ring.

2. Take a piece of string or ribbon and use a ruler.

Then put the string around your finger and then mark the end of the overlap with a pencil and measure the marked distance with the ruler. 

Finally, the result obtained in millimeters corresponds to the size of your ring.

Example: a 4.9 cm ring corresponds to ring size 49.
