How to find your ring size

Use a ribbon, measuring tape or thin and long paper. Wrap it around the KNOT of the finger you want to measure, keeping it neither loose nor too tight until one end of the ribbon/tape/ paper meets the other. Use a marker to make a mark when the two ends meet.

Open the ribbon/ tape/ paper and place it along a ruler to measure the length (millimetres) until the point where you made the mark. According to the length (millimetres/mm), you will find your finger size on the following board. For example, if the length is 16,2 mm, your size is 51.
