Here is a complete breakdown of normal and abnormal blood pressure ranges based on current guidelines (AHA/ACC, including the 2025 updated guideline):
Blood Pressure Categories (Adults)
| Category | Systolic (mmHg) | Diastolic (mmHg) | |
|---|---|---|---|
| Normal | < 120 | AND | < 80 |
| Elevated | 120 - 129 | AND | < 80 |
| High BP Stage 1 | 130 - 139 | OR | 80 - 89 |
| High BP Stage 2 | ≥ 140 | OR | ≥ 90 |
| Hypertensive Crisis | > 180 | AND/OR | > 120 |
| Low (Hypotension) | < 90 | OR | < 60 |
Key Points
- Normal = systolic < 120 AND diastolic < 80 mmHg
- The top number (systolic) = pressure when the heart beats
- The bottom number (diastolic) = pressure when the heart rests between beats
- Typical averages by age group:
- Ages 18-39: ~115/75 mmHg
- Ages 40-59: ~120/80 mmHg
- Ages 60+: ~125/80 mmHg
Special Populations
- Children: Normal BP is defined by age, sex, and height percentiles - not a single fixed number
- Pregnant women: BP should stay below 120/80; readings of 140/90 or higher indicate gestational hypertension
- CKD patients: Target is often < 130/80 mmHg
The threshold for diagnosing hypertension was lowered from 140/90 to 130/80 mmHg in the 2017 AHA/ACC guidelines, and this remains the standard in the 2025 AHA/ACC guidelines. This means "elevated" BP (120-129/<80) is a pre-hypertension warning zone that warrants lifestyle changes.
