Blood pressure (BP) varies by age, but for adults the definition of “normal” is the same regardless of age.
🔹 Adults (18 years and older)
According to major heart associations:
- 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+
- Hypertensive crisis: 180+ / 120+ (medical emergency)
👉 Even in older adults, normal is still under 120/80, although doctors may individualize targets based on health conditions.
🔹 Children and Teens
For children, normal blood pressure depends on:
- Age
- Sex
- Height
Instead of fixed numbers, doctors use percentile charts. However, here are rough averages:
| Age | Approximate Normal BP |
|---|---|
| Newborn | 60–90 / 20–60 |
| Infant (1–12 months) | 80–100 / 50–65 |
| Toddler (1–3 yrs) | 90–105 / 55–70 |
| Preschool (4–5 yrs) | 95–110 / 60–75 |
| School age (6–12 yrs) | 100–120 / 60–75 |
| Teen (13–17 yrs) | Similar to adults |
🔹 Older Adults (60+)
While arteries naturally stiffen with age, most guidelines still aim for:
- Under 130 / 80 (if tolerated safely)
Doctors may allow slightly higher targets in frail elderly patients to prevent dizziness or falls.
Important Notes
- Blood pressure naturally fluctuates during the day.
- Stress, caffeine, pain, and exercise can temporarily raise it.
- A single high reading does not mean you have hypertension.
- Proper measurement technique matters (seated, rested 5 minutes, arm at heart level).
If you’d like, tell me your age and recent reading, and I can help you interpret it.
