🩺Blood Pressure Checker
Enter a blood pressure reading you measured to see which standard AHA category it falls into — not a measurement tool, not a diagnosis.
Enter the numbers from your blood pressure monitor or cuff reading. This tool categorises the reading — it cannot measure your blood pressure.

This tool categorises a blood pressure reading you measured with a separate device — it cannot measure your blood pressure. Categories are general reference based on American Heart Association 2025 guidelines and are not a diagnosis. Blood pressure varies with time of day, activity, stress, and other factors; a real diagnosis requires repeated measurements taken by a healthcare professional. For a hypertensive crisis reading (systolic above 180 and/or diastolic above 120), seek urgent professional advice; call emergency services immediately if you have symptoms such as chest pain, shortness of breath, vision changes, or weakness. Never start, stop, or change medication or treatment based on this tool — speak with a doctor.
Free Blood Pressure Checker
Took a blood pressure reading and not sure what it means? Our free Blood Pressure Checker helps you make sense of it. Enter the systolic and diastolic numbers you measured, and the tool shows which standard category they fall into—from normal and elevated through stage 1 and stage 2 high blood pressure—based on the American Heart Association's guidelines.
It's a reference, not a replacement for a real measurement or a doctor. This tool doesn't measure your blood pressure and doesn't diagnose anything; a single reading can vary with time of day, stress, and activity, and a real diagnosis needs repeated readings taken by a professional. If your numbers fall in a very high range, the tool clearly flags when to seek urgent care.
