Children and Adults: Measure the wrist just below the wrist bone with a tape measure. If you don't have a tape measure, use a piece of string and then measure it with a ruler.
For adults: Add 3/4 to 1 inch (depending on how loose you like your bracelets) to your measurement and that will be the size you order. If this is a gift and you cannot measure, use the approximate sizing chart.
For children: Add 1/2 inch for ages 3 and under. For ages 3 and up add 3/4 inch or use the sizing chart below. Please note, these size are approximate. Measuring is the best way to ensure a proper fit.
