The correct ring size

We specify the ring sizes at Sono Jewelery as the inner circumference of the ring in mm. You can use a thread or a strip of paper to determine the correct inner circumference of the ring. Simply wrap the thread or strip of paper tightly around the area on the finger for which the ring is intended and then measure the length. The length determined in this way is then the inner circumference of the ring in millimeters. If you only know the inner diameter of the ring, you just need to multiply it by the value 3.14 (pi). You can also easily calculate the inner circumference of the ring. You can also easily determine your ring size using our ring template. Simply download the template here.
