Blood Pressure Category

About this calculator

This tool takes your systolic (top number) and diastolic (bottom number) blood pressure readings and matches them against the American Heart Association's classification — Normal, Elevated, Hypertension Stage 1, Hypertension Stage 2, and Hypertensive Crisis — the same category boundaries doctors and home blood pressure monitors use to flag a reading.

Anyone tracking their blood pressure at home with a cuff monitor uses this to make sense of the two numbers, since the category depends on whichever number (systolic or diastolic) falls into the higher-risk band, not just one of them in isolation. It's commonly used alongside routine checkups or after starting a home-monitoring habit recommended by a doctor, though — as the tool itself notes — the result is informational and not a medical diagnosis.
