Ring Sizing Guide
Method 1: Measuring
Take a ring that fits you well, preferably a wedding ring.
Use a ruler to check the inner diameter of the ring and choose the corresponding size in the table below: for instance, if the inner diameter of your ring is 1.66 cm, your size is 52. If the diameter measured falls between two sizes, choose the bigger one.

Method 2: Print Sheet
Use a ruler to make sure that the “2 cm” reference scale at the bottom is accurate.
If the printed scale doesn’t match (for example, if it measures 1.9 cm with the ruler), then don’t use the circle to pick the size.
Pick the size by resting the ring on the sheet of paper. The inner diameter of the ring must match the diameter of one of the circles.
