Ring Sizing Guide

1. Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inch).
2. Wrap it around the base of the appropriate finger.
3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
5. Use the chart below to determine your UK ring size.
6. If the size of your finger below the knuckle drastically differs in size from the knuckle itself, measure your knuckle as well. Then, choose a size that falls more in the middle of these two measurements. (Optional)
