“Normal blood pressure” doesn’t change dramatically by age in healthy guidelines—most medical organizations now use one general target for adults, with only slight differences for children and older adults based on overall health.
Blood pressure is measured as:
- Systolic (top number): pressure when heart beats
- Diastolic (bottom number): pressure when heart rests
🩺 Normal blood pressure by age group
👶 Children (1–12 years)
Normal values vary by height and age, but generally:
- Typical range: ~90/60 to 110/70 mmHg
- Higher or lower can still be normal depending on growth and body size
🧑 Teenagers (13–18 years)
- Normal: around 100/60 to 120/80 mmHg
- Close to adult ranges by late teens
🧑🦱 Adults (18–59 years)
Modern guideline (most important):
- Normal: less than 120/80 mmHg
- Elevated: 120–129 / less than 80
- High blood pressure (Stage 1): 130–139 / 80–89
- High blood pressure (Stage 2): ≥140 / ≥90
👴 Older adults (60+ years)
- Still ideally: below 120/80 mmHg if tolerated
- Many doctors consider up to 130–139 / 80–89 acceptable depending on health conditions
- Too low blood pressure in elderly can also cause dizziness or falls
⚠️ Low blood pressure (hypotension)
Generally:
- Below 90/60 mmHg
It may be normal for some people, but can cause:
- Dizziness
- Weakness
- Fainting
📊 Quick reference chart
| Age group | Normal BP |
|---|---|
| Children | ~90/60 – 110/70 |
| Teens | ~100/60 – 120/80 |
| Adults | <120/80 |
| Older adults | Ideally <130/80 (individualized) |
🧠 Important truth
Doctors focus less on age-specific “perfect numbers” and more on:
- Heart disease risk
- Diabetes
- Kidney health
- Symptoms (dizziness, headaches, fatigue)
🚨 When to worry
Seek medical advice if:
- Repeated readings ≥140/90
- Sudden very low BP with fainting
- Chest pain, severe headache, or shortness of breath
✔️ Bottom line
The safest general target for most people is:
👉 Around 120/80 mmHg or lower
