Measure ring size

If you plan to buy a ring for yourself or someone else, it is important to know the right ring size. A convenient way to calculate the circumference of your finger yourself is to wrap the rope around your finger and measure the number of millimeters with a measuring tape. The length of the ribbon is the circumference of your finger. Check the table below to see which ring size best fits your circumference.
