ring size

One of the easiest ways to find out the ring size is to measure it with a thread. Place the thread tightly around the part of the finger where you want the ring to fit. Also make sure that the thread fits over the knuckle, as some people have a thicker middle of the finger. You can then knot the thread and cut it off exactly where the ends of the thread meet. Measure this piece of string to find the right ring size.
