Determining your Bangle Size

Whats my bangle size? 

You can measure the inner diameter of a bangle that you own, that fits you well and go with that, or you can measure your hand.

Measuring Your Hand

Finding a bangle that is the right size is more about the circumference of the widest part of your hand, than the size of your wrist. Tuck your thumb in towards the palm of your hand, as if you were about to put on a bangle, and then use a tape measure to find the widest point over your knuckles.

You want your bangle to fit over your knuckles, but also to be snug enough that it won't slide off your hand.
