The iHealth blood pressure monitor included with Lark's Hypertension Care Program has a one-size cuff that fits arms with a circumference between 22 and 42 centimeters.
If your arm falls outside this range and the cuff doesn't fit properly, contact our support team via the webform and we'll arrange an alternative for you.
