Determine ring size

How to find your ring size

The German ring size corresponds to the inner circumference of the ring in millimeters. You can determine your size in one minute using a well-fitting ring you already own.

Method 1: Measure an existing ring

  1. Place a ring that fits well on the desired finger on a ruler.
  2. Measure the inner diameter in millimeters, from inner edge to inner edge.
  3. Find your size in the table.
Inner diameter Ring size
15.9 mm 50
16.6 mm 52
17.2 mm 54
17.8 mm 56
18.5 mm 58
19.1 mm 60
19.7 mm 62
20.4 mm 64

Method 2: Measure your finger

Wrap a narrow strip of paper tightly around the widest part of your finger, mark the overlap, and measure the length in millimeters. This value is your ring size.

Tips for an accurate result

  • Measure in the evening and at normal room temperature. Cold fingers are thinner.
  • The ring must fit over your knuckle.
  • Wide rings fit tighter. When in doubt, choose one size larger.
  • If you are between two sizes, choose the larger one.
