International Ring Size
How to find your ring size?
If you'd like to measure your ring size yourself, here are 4 easy steps.
1.Wrap a thin strip of paper or string around the base of the finger that will wear the ring.
2.Mark the point at which the string or paper meets itself.
3.Use a ruler to measure the length of the string/paper from its tip to the mark you made. This is your finger's measurement.
4.Using the chart below, match the measurement to your ring size.
