Blood pressure varies with age, but “normal” values are generally defined as systolic/diastolic (mmHg) levels considered healthy for most individuals. Here’s a standard guideline by age group:
1. Children and Adolescents
| Age | Normal Blood Pressure (mmHg) |
|---|---|
| 1–3 years | ~85–105 / 50–70 |
| 4–5 years | ~90–110 / 55–75 |
| 6–9 years | ~95–115 / 60–75 |
| 10–12 years | ~100–120 / 60–80 |
| 13–15 years | ~105–125 / 65–85 |
| 16–18 years | ~110–130 / 65–85 |
Children’s BP is often assessed using percentile charts because normal values vary by age, sex, and height.
2. Adults
| Age Group | Normal Blood Pressure (mmHg) |
|---|---|
| 18–39 | <120 / <80 |
| 40–59 | <130 / <85 |
| 60+ | <140 / <90 |
Most guidelines (like American Heart Association) recommend keeping BP below 120/80 for optimal health, but slight increases are expected with age.
3. Older Adults (70+)
- Normal is often considered <150/90 mmHg, because slightly higher pressures may be acceptable to reduce risk of falls or other complications.
Key Notes
- Systolic BP (top number) tends to rise with age due to arterial stiffness.
- Diastolic BP (bottom number) may decrease after age 60.
- Individual factors (weight, activity level, medications, chronic diseases) influence what is “normal.”
- Regular monitoring is recommended for everyone, especially adults over 40.
If you want, I can make a quick age-based chart from 0–100 years showing approximate “normal” BP for each decade—easy to reference at a glance. Do you want me to do that?
