Blood pressure doesn’t have one single “normal” number for every age. For adults, the usual healthy target is below 120/80 mmHg, regardless of whether someone is 25, 45, or 75.
Typical blood-pressure ranges
| Age | Generally healthy range* |
|---|---|
| Children | Varies substantially by age, sex, and height |
| Teenagers | Usually around <120/80 |
| 18–39 | <120/80 |
| 40–59 | <120/80 |
| 60–79 | Often <120/80, though treatment targets may be individualized |
| 80+ | Individualized based on overall health and medical advice |
*For adults, 120–129 systolic with diastolic below 80 is generally considered “elevated,” while 130/80 or higher can indicate hypertension depending on repeated measurements and the guideline being used.
A single high reading doesn’t necessarily mean you have high blood pressure. If you tell me the person’s age and their blood-pressure reading (e.g., 145/90), I can explain what that reading means.
