You can easily select the right size in a bangle that has no opening or clasp in just three steps.
Sizing is important to ensure the bangle will slide over your hand and onto your wrist.
Step 1: Make a fist.
Step 2: Measure the length from the outside of the first knuckle to the point between the third and fourth knuckle.
Step 3: This measurement equals the required diameter (for example, if the measurement is 65mm, then a 65mm would be the size of the bangle you need).
As a guide, bangle sizes are commonly written first in a description, with the thickness or the width of the metal second.
Ie. 65x4mm = 65mm being the bangle diameter and 4mm the thickness.
