Blood pressure doesn’t have one single “normal” value for each age. For most adults, a blood pressure around 120/80 mmHg is considered healthy, and the same general adult categories are used regardless of age.
Typical blood-pressure ranges
| Age | Generally healthy/normal range* |
|---|---|
| Newborns | ~60–80 / 30–45 mmHg |
| Infants | ~70–100 / 50–65 mmHg |
| Children 1–5 | ~80–110 / 50–80 mmHg |
| Children 6–12 | ~90–120 / 60–80 mmHg |
| Teenagers | ~100–120 / 60–80 mmHg |
| Adults 18+ | <120 / <80 mmHg |
*Children’s blood pressure is interpreted using age, sex, and height percentiles, so these are only rough ranges.
For adults, a commonly used classification is:
-
Normal: <120 / <80
-
Elevated: 120–129 / <80
-
High blood pressure (stage 1): 130–139 or 80–89
-
High blood pressure (stage 2): ≥140 or ≥90
-
Very high: ≥180 and/or ≥120 — especially concerning if accompanied by symptoms.
If you tell me the person’s age, sex, and their blood-pressure reading (for example, 145/92), I can explain what that reading means.
