What Is a Normal Blood Pressure Reading by Age?
Quick answer
- For most adults, a normal blood pressure is below 120/80 mmHg.
- Readings from 130/80 mmHg and above are usually considered high.
- Targets can differ with age and conditions such as diabetes or kidney disease, so your doctor will set the target that suits you.
Understanding the Two Numbers
- Systolic (top number): pressure when the heart pumps.
- Diastolic (bottom number): pressure when the heart rests between beats.
General Blood Pressure Categories for Adults
- Normal: below 120/80 mmHg.
- Elevated: systolic 120 to 129 with diastolic below 80.
- High blood pressure (stage 1): 130 to 139 over 80 to 89.
- High blood pressure (stage 2): 140/90 mmHg or above.
- Hypertensive crisis: above 180/120 mmHg needs urgent medical attention, especially with chest pain, breathlessness, severe headache or weakness.
Different guidelines use slightly different cut-offs, so your doctor's advice is the final guide.
Does Normal Blood Pressure Change With Age?
Blood pressure tends to rise with age as arteries stiffen, but a higher reading with age does not make it healthy. Many guidelines still aim for readings near the normal range in adults, adjusted for health and tolerance. In very elderly or frail people, targets may be individualised. Children and teenagers have separate charts based on age, sex and height.
Blood Pressure Targets With Diabetes
People with diabetes are often advised a target of below 130/80 mmHg, if it can be reached safely, because high pressure adds to the risk of heart, kidney and eye problems.
How to Measure Properly
- Rest for five minutes, seated with back supported and feet flat.
- Keep the arm at heart level, with the correct cuff size.
- Avoid caffeine, smoking and exercise for 30 minutes before.
- Take two readings, one minute apart, and record them.
When to See a Doctor
See a doctor if readings are repeatedly high, or if you have symptoms such as headache, chest pain, vision changes or breathlessness. Even without symptoms, high blood pressure can silently damage the heart and kidneys.
Key Takeaways
- Normal blood pressure is generally below 120/80 mmHg.
- Readings of 130/80 and above are considered high.
- Targets are individualised, especially with diabetes.
- Measure correctly and record readings.
