Is Your Cuff the Right Size?

Getting size right is critical to accurate readings. Here's how to be sure.

First, measure your arm by wrapping a flexible tape measure around your bicep at mid-arm (see photo below). This will give you your arm circumference in centimeters (cm).

Then use the chart below to find your cuff size. Note that adjustable cuffs may fit more than one size. Check the product packaging to make sure a cuff is appropriate for you.
