There isn’t one different “normal” blood pressure number for every age. For adults, healthy blood pressure is generally assessed using the same thresholds rather than an age-specific chart.
Adult blood pressure ranges
| Blood pressure | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | and <80 |
| Elevated | 120–129 | and <80 |
| High (Stage 1) | 130–139 | or 80–89 |
| High (Stage 2) | ≥140 | or ≥90 |
| Very high | >180 | and/or >120 |
A single high reading doesn’t necessarily mean you have hypertension. Blood pressure varies with stress, exercise, caffeine, illness, and even how the measurement is taken. Repeated readings taken correctly are much more useful.
For children and teenagers, normal blood pressure is different and depends on age, sex, and height, so an adult chart shouldn’t be used.
If you give me the person’s age and their blood-pressure reading (for example, 145/90), I can explain what it means.
