Choosing the Cuff Size
How to measure at home for your cuff size:
Grab a tape measure, piece of string or a strip of paper.
Wrap the tape measure around your wrist below the wrist bone, with the numbers facing out. Adjust for a comfortable fit.
Find your measurement, compare it to the size chart and choose the appropriate cuff size. If you are between two sizes, I suggest you opt for the larger size.
