About Blood Pressure Calculator
This blood pressure calculator uses the American Heart Association (AHA) 2024 guidelines to classify your systolic and diastolic readings into categories ranging from low (hypotension) to hypertensive crisis. It also calculates your pulse pressure and mean arterial pressure (MAP) — two additional markers of cardiovascular health that give a fuller picture beyond a standard reading. Enter your numbers using the inputs or arrow buttons, and the tool instantly shows your category, what it means, and practical lifestyle recommendations tailored to your result.
