Here’s a clear and complete guide to normal blood pressure values by age.
🫀 Understanding Blood Pressure
Blood pressure is written as Systolic / Diastolic (mmHg).
- Systolic (top number): Pressure when your heart beats
- Diastolic (bottom number): Pressure when your heart rests
Example: 120/80 mmHg = normal adult reading
👶 Children (Under 13 Years)
Normal BP depends on age, sex, and height percentile, but typical ranges are:
| Age | Approximate Normal BP (mmHg) |
|---|---|
| Newborn | 60–90 / 20–60 |
| 1–12 months | 80–100 / 50–65 |
| 1–5 years | 90–110 / 55–75 |
| 6–12 years | 100–120 / 60–75 |
⚠️ Pediatricians use percentile charts for exact interpretation.
👦 Teens (13–17 Years)
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| High BP Stage 1 | 130–139 | 80–89 |
| High BP Stage 2 | ≥140 | ≥90 |
👨 Adults (18–59 Years)
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| High BP Stage 1 | 130–139 | 80–89 |
| High BP Stage 2 | ≥140 | ≥90 |
| Hypertensive Crisis | ≥180 | ≥120 |
👴 Adults 60+
- Guidelines often aim for <130/80 mmHg, if tolerated.
- Some providers accept <140 systolic depending on overall health.
⚠️ Key Notes
- Blood pressure fluctuates during the day.
- Diagnosis requires multiple readings.
- Home monitoring helps track trends.
