1. Get a non-stretchy string (or paper).
2. Wrap it around the spot of your finger where you intend to wear the ring. It has to fit snug, but not too tight.
3. Mark the point on the string (or paper) where it overlaps forming a circle.
4. Measure the length of the string (or paper) and check for the corresponding ring size in the chart.
Step 1: Find a ring that already fits your finger well.
Step 2: Use a ruler to measure the inside diameter of this ring. Please measure straight across the inside of the ring from edge to edge.
