Here’s a clear overview of normal blood pressure values by age based on standard clinical guidelines (systolic/diastolic in mmHg):
1. Children and Adolescents
| Age | Normal Systolic (mmHg) | Normal Diastolic (mmHg) |
|---|---|---|
| 1–3 years | 80–110 | 50–80 |
| 4–6 years | 85–110 | 55–80 |
| 7–12 years | 90–120 | 60–80 |
| 13–17 years | 95–135 | 65–85 |
Note: Pediatric blood pressure varies by height percentile and sex, so these are approximate averages.
2. Adults (18–59 years)
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | 90–119 | 60–79 |
| Elevated | 120–129 | <80 |
| Hypertension Stage 1 | 130–139 | 80–89 |
| Hypertension Stage 2 | ≥140 | ≥90 |
3. Older Adults (60+ years)
-
Some guidelines (e.g., ACC/AHA) maintain the same adult ranges, but slightly higher systolic pressure up to 140 mmHg can be tolerated depending on health status.
-
Diastolic pressure <90 mmHg is generally targeted.
Quick Tips
-
Consistent readings: Blood pressure should be measured multiple times on different days.
-
Lifestyle matters: Healthy diet, regular exercise, weight control, and reduced sodium help maintain normal BP.
-
Seek care if: Systolic ≥140 mmHg or diastolic ≥90 mmHg consistently, or if symptoms like dizziness, headache, or chest pain occur.
