Here’s a clear, up-to-date guide to normal blood pressure values by age.
🫀 What Blood Pressure Numbers Mean
Written as: Systolic / Diastolic (mmHg)
- Systolic (top): Pressure when the heart beats
- Diastolic (bottom): Pressure when the heart relaxes
Example: 120/80 mmHg
👶 Children (Under 13 Years)
For children, “normal” depends on age, sex, and height percentile. Doctors use growth charts, but approximate resting ranges are:
| Age | Typical Range (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 |
⚠️ A pediatrician must interpret readings using percentiles.
👦 Teens (13–17 Years)
Same categories as adults:
- Normal: Below 120/80
- Elevated: 120–129 / <80
- High (Stage 1): 130–139 / 80–89
- High (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+
Targets may vary based on overall health:
- Many guidelines aim for under 130/80 if tolerated.
- Some older adults may have a goal under 140 systolic, depending on medical conditions.
Treatment goals are individualized.
🧪 Important Notes
- Blood pressure naturally fluctuates throughout the day.
- Diagnosis requires multiple readings on different days.
- Home monitoring can be very helpful.
🚨 Seek Immediate Care If:
- BP is 180/120 or higher
- Chest pain
- Shortness of breath
- Vision changes
- Severe headache
If you’d like, you can share your current reading and age, and I’ll help interpret what category it falls into.
