Blood Pressure Calculator
Classify a blood pressure reading using standard AHA/ACC ranges and see related vital-sign numbers.
Systolic (top number)
mmHg
Pressure while the heart is contracting
Diastolic (bottom number)
mmHg
Pressure while the heart is resting between beats
Resting Heart Rate

⚠️ This reading falls in the range AHA calls a hypertensive crisis. If you also have chest pain, shortness of breath, vision changes, numbness, or trouble speaking, call your local emergency number now. Otherwise, contact a doctor promptly to confirm the reading.

📊 AHA Category Reference

Category Systolic Diastolic

How this is classified

MAP = Diastolic + ⅓(Systolic − Diastolic)  |  Pulse Pressure = Systolic − Diastolic
  • Categories follow the American Heart Association / ACC 2017 guideline, which uses whichever number (systolic or diastolic) falls in the higher category
  • Pulse Pressure is the gap between the two numbers — a very high pulse pressure can reflect stiffer arteries, especially with age
  • Mean Arterial Pressure (MAP) approximates average pressure in the arteries over one heartbeat cycle
  • A single reading can be affected by stress, caffeine, recent activity, or "white coat" anxiety — trends over multiple readings matter more than any one number
⚠️ This tool applies public AHA/ACC reference ranges for education only — it is not a diagnosis and does not calculate personal cardiovascular risk. Readings can vary by device, arm position, and time of day. Please discuss your blood pressure, and any factors selected above, with a doctor or other qualified clinician.
