How to measure your finger for ring size?

Measure the diameter (distance across) in milimeters of a ring you currently wear. Find the nearest measurement on the chart below. That's approximately your ring size. (When in doubt between two sizes, it is always safer to go to the next larger ring size. This ensures your new ring will fit you.)
<< An example of measuring the diameter of a ring. The inside of this ring is approximately 18mm in diameter, making it a size 7 on the chart below.
