What Is a Normal Blood Pressure Reading by Age?
A Complete UK Guide to Healthy Blood Pressure Levels
Published by Spinegear Health Advice
High blood pressure affects millions of people across the UK, yet many are unaware they have it because it often causes no noticeable symptoms. That's why it is commonly referred to as the "silent killer."
Whether you're monitoring your blood pressure at home, have recently been diagnosed with hypertension, or simply want to understand what your readings mean, knowing what is considered a normal blood pressure reading by age is essential.
In this comprehensive guide, we'll explain what blood pressure numbers mean, provide an easy-to-understand blood pressure chart, discuss how blood pressure changes as you age, and share expert advice on maintaining healthy readings.
What Is Blood Pressure?
Blood pressure is the force of your blood pushing against the walls of your arteries as your heart pumps blood around your body.
Every blood pressure reading consists of two numbers.
Systolic Pressure
The top number measures the pressure when your heart contracts and pumps blood around your body.
Example:
120 /80 mmHg
120 represents your systolic pressure.
Diastolic Pressure
The bottom number measures the pressure when your heart relaxes between heartbeats.
Example:
120/80 mmHg
80 represents your diastolic pressure.
Blood pressure is measured in millimetres of mercury (mmHg).
Blood Pressure Categories (UK Adults)
| Category | Systolic | Diastolic |
|---|---|---|
| Low Blood Pressure | Below 90 | Below 60 |
| Healthy Blood Pressure | Below 120 | Below 80 |
| Elevated Blood Pressure | 120–129 | Below 80 |
| High Blood Pressure (Stage 1) | 130–139 | 80–89 |
| High Blood Pressure (Stage 2) | 140 or above | 90 or above |
| Hypertensive Crisis | 180 or above | 120 or above |
Important: One high reading does not necessarily mean you have hypertension. Blood pressure naturally changes throughout the day. Speak with your GP if your readings remain consistently high.
Normal Blood Pressure by Age
Many people ask:
Does blood pressure increase with age?
The answer is yes—but only slightly.
Blood vessels naturally become less flexible as we age, which can lead to gradually higher blood pressure. However, healthy lifestyle choices can help maintain normal blood pressure throughout life.
Blood Pressure by Age Chart
| Age | Ideal Blood Pressure |
|---|---|
| 18–29 years | Around 120/80 mmHg |
| 30–39 years | Around 120/80 mmHg |
| 40–49 years | Below 130/80 mmHg |
| 50–59 years | Below 130/80 mmHg |
| 60–69 years | Below 135/85 mmHg (individual targets may vary) |
| 70+ years | GP may recommend personalised targets based on overall health |
Rather than focusing solely on age, healthcare professionals consider your overall cardiovascular risk, medical history and any existing conditions when assessing blood pressure.
Is 120/80 the Perfect Blood Pressure?
Many people believe 120/80 mmHg is the "perfect" blood pressure.
In reality, blood pressure naturally fluctuates throughout the day due to factors such as:
- Physical activity
- Stress
- Sleep
- Meals
- Caffeine
- Temperature
- Hydration
Small daily variations are completely normal.
What Causes High Blood Pressure?
Several lifestyle and health factors can contribute to high blood pressure, including:
- Being overweight
- Eating too much salt
- Lack of exercise
- Smoking
- Excessive alcohol consumption
- Chronic stress
- Family history
- Diabetes
- Kidney disease
- Sleep apnoea
Often, there is no single identifiable cause.
Symptoms of High Blood Pressure
High blood pressure usually has no symptoms, making regular monitoring particularly important.
In severe cases, some people may experience:
- Persistent headaches
- Blurred vision
- Nosebleeds
- Chest pain
- Shortness of breath
- Dizziness
If you experience severe symptoms or extremely high readings, seek urgent medical advice.
How to Measure Blood Pressure Correctly
For the most accurate results:
✔ Sit quietly for five minutes.
✔ Keep both feet flat on the floor.
✔ Rest your arm at heart level.
✔ Place the cuff on your bare upper arm.
✔ Avoid talking during the measurement.
✔ Take two readings one to two minutes apart.
Using a clinically validated automatic monitor at home can help you track changes more consistently.
When Is Blood Pressure Too High?
Generally, you should contact your GP if your home blood pressure readings are consistently:
- 140/90 mmHg or higher
- Increasing over several days
- Accompanied by symptoms such as chest pain, severe headache or blurred vision
If your blood pressure is 180/120 mmHg or higher, seek urgent medical advice immediately.
Can Blood Pressure Be Too Low?
Low blood pressure (hypotension) is generally considered:
Below 90/60 mmHg
Some people naturally have low blood pressure without any symptoms.
However, symptoms may include:
- Dizziness
- Fainting
- Blurred vision
- Fatigue
- Nausea
If these symptoms occur regularly, speak to your healthcare professional.

Frequently Asked Questions
What is considered a normal blood pressure reading?
For most healthy adults, a reading below 120/80 mmHg is considered ideal, although individual targets may vary.
Does blood pressure naturally increase with age?
Blood pressure can rise slightly as arteries become less flexible over time. However, healthy lifestyle habits can help maintain normal levels at any age.
Is 140/90 high blood pressure?
Yes. Consistent readings of 140/90 mmHg or above are generally considered high and should be discussed with your GP.
Should I measure my blood pressure every day?
If advised by your healthcare professional or if you are monitoring hypertension, measuring at the same time each day can provide consistent results.
Which blood pressure monitor is best?
Upper arm blood pressure monitors are generally recommended for home use when used correctly. Choose a clinically validated monitor that is easy to use and fits your arm properly.
Final Thoughts
Understanding what is a normal blood pressure reading by age is an important step towards protecting your long-term health. While blood pressure naturally changes throughout the day and may vary slightly with age, consistently high readings should never be ignored.
