Blood pressure normally varies with age, sex, and health, but there are general ranges that doctors consider typical. Blood pressure is measured in millimeters of mercury (mmHg) and given as systolic/diastolic (top number / bottom number).
Here’s a general guide by age:
Children
| Age | Normal Systolic (top) | Normal Diastolic (bottom) |
|---|---|---|
| 1–3 years | 80–110 mmHg | 50–80 mmHg |
| 4–5 years | 85–115 mmHg | 55–80 mmHg |
| 6–9 years | 90–120 mmHg | 60–80 mmHg |
| 10–12 years | 95–125 mmHg | 60–85 mmHg |
| 13–15 years | 100–130 mmHg | 65–85 mmHg |
| 16–18 years | 110–135 mmHg | 65–85 mmHg |
Adults
| Age Group | Normal Systolic | Normal Diastolic |
|---|---|---|
| 18–39 | 100–129 | 65–84 |
| 40–59 | 110–139 | 70–89 |
| 60+ | 120–145 | 70–90 |
Note: Adults are generally considered to have normal blood pressure if it’s below 120/80 mmHg. Levels above that may indicate prehypertension or hypertension depending on the exact numbers.
Important Points
- Blood pressure rises naturally with age.
- Children have lower blood pressure than adults.
- Individual variation is normal: stress, activity, diet, and genetics all affect readings.
- Consistently high readings should be checked by a doctor.
If you want, I can make a clear chart showing normal blood pressure from age 1 to elderly, so you can quickly see the expected range for any age.
