Blood pressure does not have one exact “normal” number for every age, but typical healthy ranges can be used as a guide. Blood pressure is measured as systolic/diastolic (top/bottom number), in mmHg.
| Age group | Typical healthy blood pressure range |
|---|---|
| Children (1–12 years) | About 90–120 / 60–80 (varies greatly by height and development) |
| Teenagers (13–17 years) | About 100–120 / 65–80 |
| Adults (18–39 years) | Around 110–130 / 70–85 |
| Adults (40–59 years) | Around 120–135 / 70–85 |
| Adults (60+ years) | Often around 120–140 / 70–90 (individual targets vary) |
General adult categories:
- Normal: Less than 120/80
- Elevated: 120–129 systolic and less than 80 diastolic
- High blood pressure (Hypertension): Often considered 130/80 or higher (depending on guidelines and individual risk factors)
- Low blood pressure: Commonly below about 90/60, especially if it causes symptoms
A single reading does not always show your usual blood pressure. It is best measured after sitting quietly for a few minutes, and repeated readings are more useful.
If you tell me the person’s age, blood pressure reading, and whether it was taken at home or in a clinic, I can help interpret it.
