Here’s a clear, accurate guide to normal blood pressure (BP) by age, covering children, teens, adults, and older adults.
🫀 Blood Pressure Basics
BP is measured in millimeters of mercury (mmHg) as:
Systolic / Diastolic
- Systolic (top number): Pressure when the heart beats
- Diastolic (bottom number): Pressure when the heart rests
Example: 120/80 mmHg
✅ Adults (18+)
- Normal: Less than 120 / 80
- Elevated: 120–129 / <80
- High BP (Stage 1): 130–139 / 80–89
- High BP (Stage 2): ≥140 / ≥90
- Hypertensive crisis: ≥180 / ≥120 (seek emergency care)
Even in older adults, doctors usually aim for <130/80 if it’s safe.
👶 Children & Teens
BP varies based on age, sex, and height. Typical averages:
| Age | Normal BP (approx.) |
|---|---|
| Newborn | 60–90 / 20–60 |
| Infant (1–12 mo) | 80–100 / 50–65 |
| Toddler (1–3 yr) | 90–105 / 55–70 |
| Preschool (4–5 yr) | 95–110 / 60–75 |
| School-age (6–12 yr) | 100–120 / 60–75 |
| Teen (13–17 yr) | Similar to adult values |
👴 Older Adults (60+)
- Systolic pressure may rise slightly due to stiff arteries
- Some guidelines allow up to 140 systolic in frail individuals
- Targets are individualized based on overall health and medications
⚠️ Factors That Affect BP
- Stress, caffeine, pain, or exercise
- Sitting vs. standing
- Dehydration
Tip: Measure BP after 5 minutes of rest, arm at heart level, and avoid caffeine 30 minutes before checking.
I can also make a simple, easy-to-read chart showing normal BP for every age group—perfect for quick reference at home.
