1. Infants and Children
| Age | Normal Systolic (mmHg) | Normal Diastolic (mmHg) |
|---|---|---|
| Newborn (0–1 month) | 60–90 | 20–60 |
| Infants (1–12 months) | 87–105 | 55–65 |
| Toddlers (1–3 years) | 95–105 | 55–65 |
| Preschool (4–5 years) | 95–110 | 60–75 |
| School-age (6–12 years) | 95–120 | 60–80 |
| Adolescents (13–18 years) | 110–135 | 65–85 |
Note: Pediatric blood pressure norms vary slightly with sex and height percentile. Pediatricians often use BP percentiles rather than absolute numbers.
2. Adults
| Age | Normal Blood Pressure (mmHg) |
|---|---|
| 18–39 years | Around 120/80 |
| 40–59 years | Around 130/85 |
| 60+ years | Often up to 140/90 (slightly higher may be acceptable) |
Guidelines (American Heart Association / ACC):
- Normal: <120 / <80
- Elevated: 120–129 / <80
- Hypertension Stage 1: 130–139 / 80–89
- Hypertension Stage 2: ≥140 / ≥90
3. Older Adults
For adults over 65, slightly higher systolic values are sometimes considered acceptable, especially if lowering BP too aggressively causes dizziness or falls. Typically:
- Systolic: 120–150 mmHg
- Diastolic: 70–90 mmHg
💡 Key Points:
- Blood pressure varies throughout the day and with activity, stress, and posture.
- Children’s BP is more dynamic; always compare to percentiles rather than absolute cutoffs.
- Regular monitoring is important if BP is trending high.
If you want, I can make a simple chart showing “normal blood pressure by age” that’s easy to reference at a glance. It would cover newborns to older adults.
Do you want me to make that chart?
