I have made and sold leather wristbands. I usually make them 1 and 1/2 inches in width and around 7 to 8 inches in length. I have found that for petite women, I seem to make bracelets that are 4 to 5 inches for the real small wrists. I normally put two sets of snaps on one end and one set of snaps on the other end. I hope this helps.
