How to Choose Between Top-Rated Blood Pressure Monitors

Here are the features that distinguish the devices that get our top scores for accuracy, comfort, and ease of use

In our labs we test home blood pressure monitors to assess how accurately they work. Our testers compare participants’ blood pressure readings from each home monitor with readings from a sphygmomanometer, the gold standard device for taking BP.

We also evaluate how comfortable and easy the monitors are to use, because even an accurate device won’t do you a lot of good if you don’t want to use it or it’s too difficult to figure out, according to Susan Booth, CR’s test project leader for blood pressure monitors.

The good news is that a number of devices earn high marks in all categories. But that also means it can be tricky to distinguish among our four top-rated products, all of which are made by the same company.

Here’s a handy guide to help you figure out which one is right for you. CR members can also compare models side by side and review our full blood pressure monitor ratings here

If Your Arm Is Petite

When you use a home blood pressure monitor, it’s important to use a cuff that’s correctly sized for your arm. (Measure the circumference of your upper arm to find out your size.) Most of our top monitors come with a one-size-fits-most cuff. But if your arm circumference is smaller than 9 inches, you’ll want to go with the Omron Platinum BP5450 (Amazon), for which you can purchase a compatible smaller cuff size. 

(The Omron 10 Series BP7450 Blood Pressure Monitor is very similar to the BP5450 in our score and its features, but it's not the best choice for smaller arms. It comes with a stiff cuff, rather than a soft one, that does not offer a small option.)
