Ring Size graph

When measuring your hands keep in mind that temperature can effect the size of your hands. Cold weather can cause hands to shrink while warmer temperatures can cause hands to swell. Bare this in mind when measuring to make sure it does not affect your size. It is also worth knowing that thicker bands can be surprising narrow so size up. We have a ring sizing guide down below that will help you.
Falling between two sizes? We recommend ordering the larger size for a comfortable fit.
