Evaluate your blood pressure instantly and uncover actionable insights. Stay in control and reduce your heart risk with this trusted, easy-to-use tool.
Blood pressure (BP) measures the force of circulating blood on the walls of arteries, expressed as systolic over diastolic pressure in mmHg.
MAP = CO × SVR
CO = Stroke Volume × Heart Rate
MAP ≈ Diastolic + 1/3 × (Systolic - Diastolic)We apply American Heart Association (AHA) guidelines to classify BP risk:
if systolic < 120 and diastolic < 80 → Normal
if 120 ≤ systolic < 130 and diastolic < 80 → Elevated
if 130 ≤ systolic < 140 or 80 ≤ diastolic < 90 → Stage 1 Hypertension
if systolic ≥ 140 or diastolic ≥ 90 → Stage 2 Hypertension
if systolic > 180 or diastolic > 120 → Hypertensive CrisisRisk increases exponentially with BP due to endothelial damage and vascular strain.
This calculator empowers early detection and precise treatment decisions by using dynamic BP thresholds.

| Category | Systolic (mmHg) | Diastolic (mmHg) | Risk Level |
|---|---|---|---|
| Normal | < 120 | < 80 | Low |
| Elevated | 120–129 | < 80 | Moderate |
| Stage 1 Hypertension | 130–139 | 80–89 | High |
| Stage 2 Hypertension | ≥ 140 | ≥ 90 | Very High |
| Hypertensive Crisis | > 180 | > 120 | Critical |
| Risk Category | Recommendation |
|---|---|
| Low | Maintain healthy habits and monitor annually. |
| Moderate | Adopt diet/exercise changes; check monthly. |
| High | Consult your physician; consider ambulatory monitoring. |
| Very High | Begin medical treatment based on clinical guidance. |
| Critical | Immediate emergency care required to prevent organ damage. |
