Great question—blood pressure does change with age, but the idea of “normal” is a little different for kids vs. adults. Here’s a clear, practical breakdown 👇
🔹 Adults (18 years and older)
For adults, the same ranges apply at any age (18, 40, 70, etc.).
| Category | Systolic (top #) | Diastolic (bottom #) |
|---|---|---|
| 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 |
✅ Normal adult BP: ~120/80 mmHg
Even though BP tends to rise with age, higher numbers are not considered “normal” just because someone is older.
🔹 Children & Teenagers (1–17 years)
For kids, blood pressure is based on age, sex, and height percentile, so there’s no single number. These are approximate averages:
| 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 |
Doctors usually use percentile charts for kids to decide what’s normal or high.
🔹 Older Adults (65+)
- Target is still under 120/80 if it can be reached safely
- Some doctors accept under 130/80 if there’s dizziness or fall risk
- Very low BP can also be a problem in seniors
Quick takeaway
- Adults: Normal = <120/80
- Kids: Depends on age, height, and sex
- Older adults: Same goals, but treatment is individualized
If you want, tell me your age (or whether this is for a child or adult), and I can help interpret specific readings 📊💙
