Here’s a clear guide to normal blood pressure values by age, covering children, teens, adults, and seniors.
🫀 Blood Pressure Basics
Blood pressure (BP) is measured as Systolic / Diastolic (mmHg):
- Systolic (top number): Pressure when the heart contracts
- Diastolic (bottom number): Pressure when the heart relaxes
Example: 120/80 mmHg = normal adult reading
👶 Children (Under 13 Years)
BP varies with age, sex, and height, but typical ranges are:
| Age | Systolic (mmHg) | Diastolic (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 precise evaluation.
👦 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+
- Many guidelines aim for <130/80 mmHg, if tolerated.
- Some doctors accept <140/90 depending on overall health.
⚠️ Key Notes
- BP naturally fluctuates throughout the day.
- Multiple readings on different days are needed for an accurate assessment.
- Home monitoring is useful for tracking trends and preventing complications.
I can also make a visual chart of normal blood pressure by age, so you can quickly see where your readings fall.
Do you want me to make that chart?
