Blood pressure “normal values” don’t change dramatically with age in adults—the standard cutoff is mostly the same—but children and teenagers do have age-based ranges.
Here’s a clear breakdown:
🧑⚕️ Adults (18+ years)
Normal blood pressure:
- Systolic: < 120 mmHg
- Diastolic: < 80 mmHg
- Written as: <120/80 mmHg
Categories:
- Normal: <120 / <80
- Elevated: 120–129 / <80
- Hypertension Stage 1: 130–139 or 80–89
- Hypertension Stage 2: ≥140 or ≥90
- Hypertensive crisis: ≥180 and/or ≥120 (emergency)
👉 In adults, “normal” does not increase with age—even though older people more commonly develop higher BP.
👶 Children & Teens (Age-based normal varies)
Blood pressure in children depends on age, sex, and height percentile. But general approximate ranges:
Infants (0–1 year)
- ~ 70–100 / 50–65 mmHg
Toddlers (1–3 years)
- ~ 90–105 / 55–70 mmHg
Preschool (3–5 years)
- ~ 95–110 / 60–75 mmHg
School-age (6–12 years)
- ~ 97–120 / 60–80 mmHg
Adolescents (13–17 years)
- ~ 110–135 / 65–85 mmHg
📌 Key takeaway
- Adults: same standard (<120/80) regardless of age
- Children: ranges gradually increase with growth
