How to measure the diameter
Step 1 - Make sure the ring you are using is the right size to fit snugly into the finger you want to wear the new ring on.
Step 2 - Using your ruler or tape measure, measure the widest points inside the ring, side to side.
How to measure the circumference
Step 1 - Wrap the twine around the base of the finger so that it fits perfectly to its size.
Step 2 - With a ballpoint pen or marker, mark where the ends of the string or paper come together.
Step 3 - Spread the string or strip of paper on a flat surface and measure its length in millimeters. This number is the circumference of your finger!
