Blood pressure norms are a little different for adults versus children.
✅ Adults (18 years and older)
For adults, the definition of “normal” does not change with age.
🔹 Normal Blood Pressure
Less than 120 / 80 mmHg
Categories for Adults
- Normal: Under 120 / 80
- Elevated: 120–129 / Under 80
- High (Stage 1): 130–139 / 80–89
- High (Stage 2): 140+ / 90+
- Hypertensive crisis: 180+ / 120+ (seek emergency care)
Even in older adults, doctors generally aim for under 130/80, if it can be achieved safely.
✅ Children & Teens
For children, blood pressure depends on:
- Age
- Sex
- Height
Doctors use percentile charts, but here are typical averages:
| Age Group | 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 |
🔎 Important Notes
- Blood pressure naturally rises slightly with age due to stiffening arteries.
- A single high reading does not mean you have hypertension.
- Proper measurement matters: sit quietly 5 minutes, feet flat, arm at heart level.
- Stress, caffeine, and pain can temporarily raise it.
If you’d like, tell me:
- Your age
- Your recent reading
I can help you interpret whether it’s normal for you.
