There isn’t one exact “normal blood pressure” for every age. For adults, the same general blood-pressure categories are used regardless of age.
Adult blood pressure guide
| Blood pressure | Systolic (top) | Diastolic (bottom) |
|---|---|---|
| Normal | <120 | and <80 |
| Elevated | 120–129 | and <80 |
| High — Stage 1 | 130–139 | or 80–89 |
| High — Stage 2 | ≥140 | or ≥90 |
| Severely high | ≥180 | and/or ≥120 |
A single high reading doesn’t necessarily mean you have hypertension. Blood pressure should generally be measured correctly and assessed using repeated readings.
For children and teenagers, normal blood pressure is different and depends on age, sex, and height, so adult numbers shouldn’t be applied to them.
If you give me the person’s age and blood-pressure reading (for example, 65 years old, 150/90), I can explain what it means.
