We're asked very frequently by our customers about how to measure their wrists, so we wrote a little guide.
When measuring your wrist, stay as close to your hand as possible, like so (the circumference in the picture is 6.5 inches.)
All sizes are in inches. 1 inch is 2.54 centimeters.
If you don't have a measuring tape, use a piece of string or something you can mark on to measure your wrist and lay the string back out on a ruler to get your measurement in inches.
