Blood pressure doesn’t have one single “perfect” number for every age, but there are commonly accepted normal ranges used by doctors. I’ll break it down clearly and keep it practical.
First, a quick refresher
- Systolic (top number): pressure when the heart beats
- Diastolic (bottom number): pressure when the heart rests
- Written as: 120 / 80 mmHg
Normal Blood Pressure by Age
Children
Blood pressure in kids varies by age, sex, and height, but general averages are:
| Age | Normal BP (approx.) |
|---|---|
| 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 (13–17 yrs) | 110–130 / 65–85 |
Adults (18 years and older)
These ranges apply regardless of age, though risk increases as we get older.
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | Less than 120 | Less than 80 |
| Elevated | 120–129 | Less than 80 |
| High BP (Stage 1) | 130–139 | 80–89 |
| High BP (Stage 2) | 140 or higher | 90 or higher |
| Hypertensive Crisis | 180+ | 120+ |
Older Adults (60+)
There’s no separate “normal” category, but doctors often aim for:
- Around 120–130 / under 80, if tolerated
- Slightly higher systolic numbers may be acceptable to avoid dizziness or falls
Important Notes
- One high reading doesn’t mean you have hypertension
- BP can change with stress, pain, caffeine, exercise, or illness
- Home readings taken at rest are often more accurate than one-off clinic readings
If you want, tell me:
- Your age
- Your recent BP readings
- Whether this is for general info or a specific concern
I can help you interpret the numbers and what (if anything) to do next 💙
