How to measure bangles and other relevant details. If you would like to know how to measure  bangle sizes please read below :
Men's and women's bracelet sizes are given in inches, because they are flexible and can lay open, that is, they do not have to be slipped over the hand as in case of a bangle, which does not open.
Why do we not show the bangle sizes as bracelet lengths in inches too? Because two wrist size may be identical sizes but the size of the hands may vary, e.g. two women may have the same wrist size, but one may have larger or smaller hands than the other, as the bangles have to be slipped over the hand, it is prudent to take into account the diameter of the bangle which does not open. The bangle sizes are given in diameter, which is the distance, measured across the inner diameter of the bangle e.g. size 2-4/16th, 2-6/16th, 2-8/16th in Inches
Gold bangle and bracelet conversion from circumference to diameter in inches

Example : 2-4/16th inch is 2 full inches and 4 sections of the 16 sections of an inch shown on the Inch scale

Bangle sizes :  conversion  from diameter to length or  inner circumference.
