Understanding where your blood pressure reading falls compared to standard healthy ranges is one of the simplest ways to keep an eye on your cardiovascular health. This calculator compares your systolic and diastolic numbers against standard categories to show whether your reading is normal, elevated, or in a hypertension range.

Blood pressure is closely tied to overall cardiovascular risk, which is why it’s one of the key inputs in our heart age calculator. If you’re managing your health more broadly, our BMI calculator and guide on how to calculate BMI offer additional context alongside your blood pressure numbers.
