What Is a Normal Blood Pressure Reading by Age?

Blood pressure is one of the most common measurements taken during a health check. But when you see numbers like 120/80, what do they actually mean? And does what's considered normal change as you get older?

Here’s a simple guide to understanding your blood pressure numbers.

What do blood pressure numbers mean?

A blood pressure reading contains two numbers:

Systolic pressure is the top number. It measures the pressure in your arteries when your heart beats.

Diastolic pressure is the bottom number. It measures the pressure when your heart rests between beats.

So, a reading of 118/76 mmHg means a systolic pressure of 118 and a diastolic pressure of 76.

Different healthcare systems can use somewhat different thresholds. For example, the NHS generally considers 140/90 mmHg or higher in a healthcare setting, or 135/85 or higher at home, to indicate high blood pressure.

Does normal blood pressure change with age?

This is where there's often some confusion.

Blood pressure, particularly the systolic number, often increases as we get older. Changes such as increased stiffness in the arteries can contribute to this.

But that doesn't mean a higher blood pressure automatically becomes “normal” just because you're older.

For most adults, below 120/80 mmHg is still considered normal, rather than having a different normal range for your 30s, 40s, 50s or 60s. Your healthcare provider may recommend an individual target based on your overall health, medications and medical history.

One reading doesn't tell the whole story

Blood pressure can change throughout the day and can be affected by things like activity, stress and how the measurement is taken.

That's why one unusual reading doesn't necessarily mean there's a problem.

If you're monitoring your blood pressure at home, keeping a record of readings over time can give you and your healthcare provider a much clearer picture than a single measurement.
