Bracelet sizes are listed as the length of the bracelet. To measure your wrist, use a piece of string to wrap around wrist, cut where it joins and measure against a ruler. We recommend choosing a size 1-2 inches bigger than your wrist size.
Bear in mind that bracelets with thicker links will fit tighter than thinner chains as the thicker links will result in a smaller internal diameter when closed
eg. the 13mm Cuban Bracelet will fit tighter than the 6mm Cuban Bracelet at the same length and the Barbed Wire Cuban Bracelets fit tighter due to the barbed links.
