How to measure your wrist size (or circumference):

Make sure the palm of your hand is facing up.

Open your hand, doing so will ensure you get the real size of your wrist when it’s the largest.

Wrap a measuring tape around your wrist, not to tight or to lose, find a nice comfortable fit.

Read the size on the measuring tape, preferably in inches or centimeters.

That will give you an accurate bracelet and bangle measurement.
