If you want to order a bracelet or a ring and you do not know your size here is an easy tutorial.
First, measure the turn of your wrist using a meter of seamstress where you want to wear your bracelet.
Once this measurement is taken add 1 cm and you have the size of the bracelet that you must order.
Example: Your wrist is 17 cm. You will then have to take a bracelet in size 18 cm.
To check your ring size you can print the ring chart (check that the bottom bar is 1 cm)
