Bangle cores are sized based on the inside diameter of the bangle, and these diameters are largely driven by commercial availability of seamless tubing. As an example, a 2.55" ID bangle core will have an inside perimeter of 8.007" (2.55 times 3.14 (pi) = 8.007), thus it is a "woman's size 8".
However, an inside diameter of 2.32" actually has a perimeter of 7.28". So we round a little to avoid confusion. Here are the actual diameters and perimeters (or size):
2.55" ID = 8.01" perimeter (Size 8)
2.67" ID = 8.38" perimeter (Size 8.5)
Even though the Inside Diameters do not vary much, the fit on a woman's wrist will be noticeable for each change in size. Size 8 is the industry standard for most commercially available bangles and bracelets.
Here is a quick way to check sizes:
A standard Kerr canning jar has an equivalent size that is between a size 7 and 7.5, so if you cannot slip your hand into a canning jar you are not a size 7.
A 20 oz jar of Del Monte sliced peaches has an ID of 2.5" which is an equivalent of size 8.
