The size of a ring is one of those things you may not think about until you have to. When it comes time to buy the picture-perfect engagement ring for the love of your life or even just a gorgeous ring you want to treat yourself to; you need to know the proper ring size. Once you have that sorted, you can move on to bigger decisions, such as how much to spend on that special someone. Even if that someone is yourself.


1. Standard ring measurements

The first step in determining ring size is understanding standard ring measurements. In terms of engagement and wedding rings, they are usually worn on the left ring finger next to the pinkie. Millimeters is the standard ring measurement for the inner circumference. Jewelers use a standard scale for ring measurements so that every store has consistent sizes. It's similar to clothing sizes that remain the same in every region, although there may be some slight variations in fit depending on the ring itself.
