How to measure your bangle size.

Cut a strip of paper about 1 & 1/2 inches wide and
long enough to wrap around your hand with a bit of overlap. We used the length of an letter size sheet of paper.
Apply a piece of  tape to
one end so you can stick it
down with the other hand.
Scrunch your hand together to
make it as narrow as
possible to fit through a
bangle. Wrap the paper
around your hand to cover the
knuckles snuggly.

Stick down the tape. Try slipping this paper bangle on and off. You should be able to slip it on &
off without too much trouble ( you just think the paper might tear ! ). The
paper bangle does not have to stay round and can distort to fit over your
hand. In reality your hand distorts to fit through a bangle.

Cut the bangle at the
taped joint so you end up with
a flat strip of paper plus the
waste overlap piece.
Discard the waste overlap piece. Measure the remaining length. This
 will be the minimum inner circumference that will fit you comfortably.
 The diameter can also be worked out by dividing the circumference
 you have just measured by pi (3.1416). You might need a calculator
for this! The size of our bracelets are as follows:
Small is 2 3/8" dia, our Medium is 2 1/2" dia, our Med-Lg is 2 5/8",
our Large is 2 3/4" .

Please note that thinner (narrower) bracelets have less friction going over your hand. For wider bracelets it is a good idea to go a size larger. Thinner braclets can be tighter.
