Tip: When measuring your finger, your measurements need to be 100% accurate as even a fraction of a millimeter can make a difference.
Global Ring Sizing Systems
There are several systems for indicating the size of a ring used around the world:
In the United States, Canada, and Mexico, for indicating a ring size uses a numerical measure, for whole and half ring sizes. An increase of a full ring size is an increase of 0.032 inches (0.8128 mm) in diameter or roughly 1/10 inch in inside circumference.
In United Kingdom, Australia, New Zealand, South Africa, and Ireland, the ring sizes are specified using alphabetical letters, for full and half ring sizes
In Japan, India, South America, and China, ring sizes are specified using a numerical measure, that only has whole size rings, and does not have a direct correlation with diameter or circumference.
In Italy, Spain, Netherlands, and Switzerland, ring sizes are specified as the circumference minus 40mm. A 50 ISO was a 10 in Switzerland.
In France and Germany, the numbers of each size simply translate to the circumference of the inside of the ring in millimeters. So a size 40 would mean the inside circumference of a ring is also 40 mm.
