Women's rings in the U.S. are commonly between sizes 3 to 9, while men's rings are usually sized between 8 and 14, and those units match up to your finger's width in millimeters. Before you sit down to measure your ring size, there are a few things you should keep in mind:
1. Consider your knuckle. If you know your knuckle is on the larger side, you should order half a size bigger than what your finger alone indicates otherwise you won't be able slide a ring into the right place.
2. Ensure accuracy with multiple tries. R.W. Diamond Broker advises measuring your finger three to four different times because the size actually fluctuates depending on temperature, tending to be smaller the colder you are and more swollen if you're overheated.
