Measure your wrist with a strip of paper below the wrist bone, where you would normally wear the bracelet. For double bracelet wrap the paper twice.
If you are using a plain strip of paper, mark your size with a pen or a pencil, then use a ruler to measure the length.
That would be your wrist size.
To find your bracelet size, just add between one to two centimeters ( half to one inch ) depending on how tight or loose you like to wear your bracelet.

If the bracelet is a present, and you don’t have the possibility to make a measurement, you can order the average 16.5 cm bracelet with an extension chain, that will give the ability to make it bigger if needed. Simply send me the massage when ordering to include the extension chain.
