Determining the correct ring size is important! Fortunately, there are several ways to find out what your ring size is.
Option 1. The preferred way: Have your ring size measured at your local jeweler.
Option 2. Measure the inner size of a well-fitting ring. This can be done with a ruler, but is more accurate with a vernier caliper. Measure the inner diameter of the ring and look at the table below to see which size this corresponds to.
Option 3. Print this A4. Check that 1 cm = 1 cm. Take a well-fitting ring and check which circle best matches the inside of your ring.
Option 4. Don't have a well-fitting ring to measure? Take a piece of paper, string or tape measure. Pull it tight at the widest part of your finger, usually the knuckle. Measure this circumference. The measured mm is immediately the Belgian size. Round up.
