Determine size of ring

Following points must be considered by verification of size:

  • Always measure the finger on which the ring should be worn. The fingers on the left side usually have a different thickness in compare to the right ones and therefore are different in size.
  • On very warm days fingers can swell while on cold days they might often be smaller
  • The day time as well should be considered by taking measurement. It might be that your fingers are slightly thicker in evenings than in mornings.
  • Please keep in mind that your fingers in summertime usually are thicker than in winter.
  • By wider ring models (Sirup models are rather wider) often a larger ring size is needed in compare to small ones. This is caused due to that wider rings have a smaller scope around the knuckle to shift the ring up to the finger root without problems. Therefore choose a slightly bigger size.There are different possibilities to determine the ring size.

 

There are different possibilities to determine the ring size.

  1. Mesure the range around the finger with the help of a lace, yarn, paper stripe 3-5 mm width
    Wrap around lace, yarn or paper stripe around your knuckle and make a mark were the both ends are overlapping.
    Hold this measure help on a ruler and determine so the ring size. On a length of 53 mm the ring size will be 53.
  2. Measuring the inner diameter of an already fitting ring
    Take a good fitting ring from your collection and measure it with a ruler the gap between the inner edge (inner diameter). Please respect that the ring measure only works with round shaped rings.
    Multiply the result e.g. of 16.9 mm (inner diameter) with the factor 3.14 = 53.066 mm. So you get the inner diameter in mm which corresponds with the ring size 53.
