Blood pressure (BP) varies with age, height, sex (in children), and overall health—but there are typical normal ranges that doctors use as a guide.
First, a key point: BP is written as systolic/diastolic (e.g., 120/80 mmHg)
- Systolic = pressure when the heart beats
- Diastolic = pressure when the heart rests
🧍 Adults (most commonly used standard)
✅ Normal blood pressure
- Below 120 / 80 mmHg
⚠️ Elevated
- 120–129 / <80
⚠️ High blood pressure (Hypertension)
- Stage 1: 130–139 / 80–89
- Stage 2: ≥140 / ≥90
👶 Children (normal ranges vary by age)
In children, BP is not a single fixed number—it depends on age, height, and growth percentiles. But general averages look like this:
| Age | Typical Normal BP (approx.) |
|---|---|
| Newborn (0–1 month) | ~60–90 / 30–60 |
| Infant (1–12 months) | ~80–100 / 50–65 |
| Toddler (1–3 yrs) | ~90–105 / 55–70 |
| Preschool (3–5 yrs) | ~95–110 / 60–75 |
| School age (6–12 yrs) | ~100–120 / 60–80 |
| Teen (13–17 yrs) | ~110–130 / 65–85 |
👴 Older adults
- Often slightly higher is common, but still considered normal:
- Around 120–140 / 70–90
- Doctors are more careful about treatment to avoid dizziness or falls.
⚠️ Important reality check
There is no single “perfect BP for every age.” What matters most is:
- Your baseline trend
- Whether you have symptoms (headache, dizziness, chest pain)
- Risk factors (diabetes, kidney disease, etc.)
🧠 Simple takeaway
- Ideal adult BP: ~120/80
- High BP concern: consistently ≥130/80
- Low BP concern: usually <90/60 with symptoms
If you want, tell me your age and recent BP reading—I can help you interpret whether it’s normal or not.
