Ring Size Guide

Here are some tips to help you determine your ring size:

1. Use the strip of paper to measure the inner side of your existing ring.
2. Mark the point where the two ends meet.
3. To find out the internal circumference of your ring, measure the paper or string against a ruler or measuring tape.
4. To derive the diameter of your finger, divide the circumference by 3.14.
