What Is the Normal Blood Pressure for Each Age?
There is no single “normal” blood pressure number for each age. Blood pressure targets depend on overall health, medical conditions, medications, and individual risk factors. In general, a healthy adult blood pressure is often considered around:
Normal range: about less than 120/80 mmHg
- The top number (systolic) measures pressure when the heart beats.
- The bottom number (diastolic) measures pressure when the heart relaxes.
Blood pressure often rises slightly with age because arteries can become less flexible, but consistently high readings should not be considered “normal ageing.”
General Blood Pressure Ranges by Age Group
| Age Group | Common Healthy Target (Approximate) |
|---|---|
| Children | Varies greatly by height and development |
| Teens (13–17) | Usually around below 120/80 mmHg |
| Adults (18–39) | Around 90/60 to under 120/80 mmHg |
| Adults (40–59) | Often targeted below 120–130/80 mmHg depending on health |
| Adults 60+ | Many guidelines aim for below 130–140/80–90 mmHg depending on individual circumstances |
| Adults 80+ | Targets are personalised based on health, frailty, and medications |
Blood Pressure Categories (Adults)
Normal
- Less than 120/80 mmHg
Elevated
- 120–129 systolic and less than 80 diastolic
High Blood Pressure (Hypertension)
- Repeated readings of around 130/80 mmHg or higher may require medical assessment, depending on guidelines and personal risk factors.
Low Blood Pressure
- Often considered below about 90/60 mmHg, especially if it causes symptoms.
Why Blood Pressure Changes With Age
Blood pressure may increase over time due to:
- Stiffer arteries
- Less physical activity
- Weight changes
- Kidney changes
- Hormonal changes
- Long-term lifestyle factors
However, high blood pressure is not an unavoidable part of getting older and can often be managed.
When to Be Concerned
Seek medical advice if you regularly have:
- Readings above your recommended target
- Very low readings with dizziness or fainting
- Chest pain
- Shortness of breath
- Sudden weakness, confusion, or trouble speaking
A single high reading does not always mean you have hypertension—blood pressure can temporarily rise due to stress, pain, caffeine, exercise, or illness.
