What counts as good blood pressure?

Good blood pressure for most adults is below 120/80 mmHg, the range the American Heart Association calls normal. The NHS describes an ideal reading as somewhere between 90/60 mmHg and 120/80 mmHg. What counts as good for you personally also depends on your health history and what your own doctor advises.

What counts as good blood pressure?

Every reading has two numbers, measured in millimetres of mercury (mmHg). The top number is systolic pressure, the force in your arteries as your heart beats. The bottom number is diastolic pressure, the force between beats.

A good reading means both numbers sit in the healthy band. Under American Heart Association and American College of Cardiology guidance, that means a systolic below 120 and a diastolic below 80. Both have to qualify. A reading of 118/84 mmHg is not normal, because the diastolic 84 pushes it into a higher category.

The categories, from normal to high

The AHA and ACC define adult blood pressure like this:

• Normal: less than 120 systolic and less than 80 diastolic
• Elevated: 120 to 129 systolic and less than 80 diastolic
• Hypertension stage 1: 130 to 139 systolic, or 80 to 89 diastolic
• Hypertension stage 2: 140 or higher systolic, or 90 or higher diastolic
• Hypertensive crisis: higher than 180 systolic, or higher than 120 diastolic

When the two numbers land in different bands, the higher category counts.

UK guidance draws the line elsewhere. The NHS treats high blood pressure as a clinic reading of 140/90 mmHg or higher, or a home average of 135/85 mmHg or higher, and calls anything in between slightly raised. Our guide to blood pressure ranges explained sets both sets of thresholds side by side.

Does good blood pressure change with age?

The categories apply to every adult aged 18 and over. Blood pressure does tend to rise with age as arteries stiffen, but the AHA does not offer a more generous target for a later birthday. Rising readings are common, not ideal.

Treatment goals are individual, and a clinician may set a different target for someone with diabetes or kidney disease. For the numbers typically seen at different ages, see normal blood pressure by age.

How to tell if your readings are genuinely good

One number on one day proves very little. Blood pressure moves through the day, rising with activity, caffeine, stress or a rushed measurement, then settling again. A category describes an average over time, not a snapshot.

So sit quietly for five minutes before you measure, keep your back supported and both feet flat, rest your arm so the cuff sits level with your heart, then take two or three readings a minute apart and average them. Measure at roughly the same time each day and write the numbers down. Our guide to measuring blood pressure at home covers cuff fit and common mistakes, and understanding your blood pressure readings explains how to read the pattern.

When to see a doctor

Book an appointment if your home average sits at or above 130/80 mmHg, if your readings are climbing over weeks, or if you feel unwell. Also mention readings below 90/60 mmHg that come with dizziness, faintness or blurred vision, which the NHS flags as signs of low blood pressure worth checking.

Seek urgent care straight away if you record a reading higher than 180 systolic or higher than 120 diastolic. The AHA advises waiting five minutes and measuring again, then contacting your doctor without delay if it stays that high. Call emergency services immediately if a very high reading comes with chest pain, shortness of breath, weakness or numbness, vision changes, difficulty speaking or a severe headache.

Frequently asked questions

Is 120/80 good blood pressure?

It sits right on the boundary. Under AHA guidance, normal is below 120 and below 80, so exactly 120/80 mmHg is classed as elevated. The NHS describes it as the top end of ideal. Either way it is a fine place to be.

What is a good blood pressure reading for a 60 year old?

The same as for any adult, below 120/80 mmHg. Readings often creep up with age, but the healthy target does not change. If yours is consistently higher, your doctor can help you set a personal goal.

Is 110/70 good blood pressure?

Yes. Both numbers fall in the normal band under AHA guidance and inside the NHS ideal range. See what a blood pressure of 110/70 means.
