Blood pressure varies with age, activity, and individual health, but there are general normal ranges for adults and children. Blood pressure is measured as systolic/diastolic (mmHg).
🩺 Normal Blood Pressure by Age
Adults (18+)
| Age Range | Normal Systolic (top) | Normal Diastolic (bottom) |
|---|---|---|
| 18–39 | 110–125 | 70–80 |
| 40–59 | 115–130 | 75–85 |
| 60+ | 120–140 | 75–90 |
Note: Readings above 130/80 may be considered elevated or hypertension, depending on guidelines.
Children & Adolescents
Blood pressure in kids depends on age, sex, and height. General ranges:
| Age | Systolic | Diastolic |
|---|---|---|
| 1–3 yrs | 90–105 | 55–70 |
| 4–6 yrs | 95–110 | 60–75 |
| 7–12 yrs | 100–120 | 60–75 |
| 13–17 yrs | 110–135 | 65–85 |
Pediatric blood pressure is usually evaluated percentile-based, so exact numbers may vary.
⚠️ Important Notes
- Normal values vary slightly depending on the health organization and measurement method.
- Factors affecting readings: stress, activity, caffeine, medication, body position.
- Consistently high or low readings should be discussed with a healthcare professional.
