Normal blood pressure can vary with age, but the general ranges are based on guidelines from organizations like the American Heart Association (AHA). Blood pressure is measured in millimeters of mercury (mmHg) and recorded as systolic/diastolic (top number / bottom number). Here’s a breakdown by age group:
Children and Adolescents
Blood pressure in children depends on age, sex, and height. Approximate average values:
- 1–3 years: 85–105 / 50–70 mmHg
- 4–5 years: 90–110 / 55–75 mmHg
- 6–9 years: 95–115 / 60–75 mmHg
- 10–12 years: 100–120 / 60–80 mmHg
- 13–15 years: 105–125 / 65–85 mmHg
- 16–18 years: 110–130 / 65–85 mmHg
Adults
For adults, normal blood pressure is generally considered:
- Systolic: 90–120 mmHg
- Diastolic: 60–80 mmHg
Guideline by age (approximate average):
- 18–39 years: 120/80 mmHg or slightly lower
- 40–59 years: 125/80 mmHg
- 60+ years: 130/80 mmHg
Note: Slightly higher systolic values are common with age due to stiffening arteries, but diastolic usually stays around 80 mmHg.
Key Points
- Below 90/60 mmHg – considered low (hypotension).
- 120–129 / <80 mmHg – elevated blood pressure.
- 130–139 / 80–89 mmHg – stage 1 hypertension.
- 140+ / 90+ mmHg – stage 2 hypertension.
If you want, I can make a simple table showing normal blood pressure for every age from infants to elderly, which is much easier to read at a glance. Do you want me to do that?
