Normal blood pressure varies slightly by age, sex, and health status. However, medical guidelines (such as from the American Heart Association) define a general “normal” range for adults as:
Normal adult blood pressure: below 120/80 mmHg
That said, average readings tend to shift slightly with age.
🧒 Children (1–12 years)
Blood pressure depends on age, height, and sex, but approximate averages:
- Toddlers (1–3 yrs): 90–105 / 55–70
- Preschool (4–5 yrs): 95–110 / 60–75
- School age (6–12 yrs): 100–120 / 60–80
🧑 Teenagers (13–18 years)
- Normal: Around 110–120 / 65–80
- By late teens, adult standards apply (<120/80)
👩 Adults (19–39 years)
- Normal: Less than 120 / 80
- Typical average: 110–120 / 70–80
👨🦳 Middle Age (40–59 years)
- Normal: Less than 120 / 80
- Average may trend slightly higher: 115–130 / 70–85
👴 Older Adults (60+ years)
- Ideal target for most healthy adults: Below 130 / 80
- Slightly higher systolic (top number) can be common due to stiffening arteries
Example average: 120–140 / 70–90
Some doctors individualize targets for older adults, especially if they have dizziness, kidney disease, or heart conditions.
🔎 Blood Pressure Categories (Adults)
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | and <80 |
| Elevated | 120–129 | and <80 |
| High (Stage 1) | 130–139 | or 80–89 |
| High (Stage 2) | ≥140 | or ≥90 |
| Hypertensive Crisis | ≥180 | and/or ≥120 |
⚠️ Important Notes
- Blood pressure naturally fluctuates during the day.
- Readings at home are often lower than in a clinic (“white coat effect”).
- Persistent readings above 130/80 should be discussed with a doctor.
