Here are normal blood pressure (BP) values by age, presented clearly and safely (based on widely used clinical guidelines).
Blood pressure is measured in mmHg and written as systolic / diastolic.
🩺 Normal Blood Pressure by Age
Children
| Age | Normal BP |
|---|---|
| Newborn (0–1 mo) | ~60–90 / 20–60 |
| Infant (1–12 mo) | ~80–100 / 55–65 |
| Toddler (1–3 yrs) | ~90–105 / 55–70 |
| Preschool (3–5 yrs) | ~95–110 / 60–75 |
| School-age (6–12 yrs) | ~100–120 / 60–75 |
| Teen (13–18 yrs) | ~110–130 / 65–85 |
In kids, “normal” also depends on height and sex, so doctors use percentile charts.
Adults
| Age | Normal BP |
|---|---|
| 18–39 yrs | <120 / <80 |
| 40–59 yrs | <120 / <80 |
| 60+ yrs | <120 / <80 (ideal) |
| <130 / <80 (often acceptable if well-tolerated) |
👉 Key point: For adults, normal BP does NOT change with age.
Higher numbers in older adults are common—but not ideal.
🚦 BP Category Reference (Adults)
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| Hypertension (Stage 1) | 130–139 | 80–89 |
| Hypertension (Stage 2) | ≥140 | ≥90 |
| Crisis | ≥180 | ≥120 |
⚠️ Important Notes
- One high reading ≠ diagnosis
- Measure after 5 minutes of rest
- Use the correct cuff size
- Track readings over time
If you want, I can:
- Adjust this for men vs women
- Explain why BP rises with age
- Help interpret your own readings
- Turn this into a simple chart or infographic
