What Is the Normal Blood Pressure for Each Age?
There is no single “normal” blood pressure number for every age. Blood pressure goals depend on your overall health, medical conditions, medications, and risk factors. A healthy blood pressure for one person may not be the same for another.
Blood pressure is measured as:
- Systolic (top number): pressure when the heart pumps
- Diastolic (bottom number): pressure when the heart relaxes
Example: 120/80 mmHg
General Blood Pressure Ranges by Age
| Age Group | Typical Healthy Target (General Guide) |
|---|---|
| Children | Varies by age, sex, and height |
| Teenagers | Often around below 120/80 mmHg |
| Adults 18–39 | Around 90/60 to below 120/80 mmHg is often considered healthy |
| Adults 40–59 | Many people aim for around below 120–130/80 mmHg, depending on health |
| Adults 60–79 | Often personalised; many aim for controlled blood pressure below guideline thresholds |
| Adults 80+ | Targets are individualised based on health, frailty, and treatment tolerance |
Adult Blood Pressure Categories
Normal
Below 120/80 mmHg
Elevated
- Systolic: 120–129
- Diastolic: below 80
High Blood Pressure (Hypertension)
Repeated readings around:
- 130/80 mmHg or higher (classification varies slightly between guidelines)
Low Blood Pressure
Often considered:
- Below 90/60 mmHg
Low readings are not always a problem unless they cause symptoms such as dizziness, fainting, or weakness.
Why Blood Pressure May Rise With Age
Blood pressure can increase over time because of:
- Less flexible arteries
- Changes in kidney function
- Weight changes
- Lower activity levels
- Lifestyle factors
- Certain medical conditions
However, high blood pressure should not automatically be dismissed as “just ageing.”
When to Seek Medical Advice
Speak with a healthcare professional if you have:
- Consistently high readings
- Very low readings with symptoms
- Chest pain
- Severe headache with neurological symptoms
- Shortness of breath
- Sudden weakness, facial drooping, or trouble speaking
A single high reading can happen because of stress, pain, caffeine, exercise, or illness. Repeated measurements give a clearer picture.
