For adults of any age, the NHS says ideal blood pressure is 90/60 to 120/80 mmHg, and high blood pressure is 140/90 or more. The main difference by age is for people 80 and over: high is 150/90 or more, and the treatment target is below 150/90 (clinic) or 145/85 (home). Systolic pressure usually rises with age as arteries stiffen.

| Age | Ideal | High (clinic) | High (home) | Treatment target (clinic) |
|---|---|---|---|---|
| 18–39 | 90/60 – 120/80 | 140/90+ | 135/85+ | Below 140/90 |
| 40–59 | 90/60 – 120/80 | 140/90+ | 135/85+ | Below 140/90 |
| 60–79 | 90/60 – 120/80 | 140/90+ | 135/85+ | Below 140/90 |
| 80+ | 90/60 – 120/80 | 150/90+ | 145/85+ | Below 150/90 |
Based on NHS guidance and NICE NG136. Your GP may set a personal target if you have other conditions.
Why blood pressure rises with age
As we get older, the large arteries become stiffer, which tends to push the top (systolic) number up. The bottom (diastolic) number often levels off or falls after about 60. This is why many older people have a high systolic reading with a normal diastolic one (isolated systolic hypertension). It is common, but it is not harmless – it still raises the risk of stroke and heart disease, and it can be treated.
Blood pressure in older adults
- Over 80: NICE uses a higher clinic target (below 150/90) because very low readings can cause dizziness and falls.
- Postural (orthostatic) hypotension: a fall in blood pressure when standing up is more common with age. Your GP may check your blood pressure sitting and standing.
- If you take blood pressure tablets and feel dizzy or faint, tell your GP – do not just stop your medicine.
Blood pressure for women and men
The NHS uses the same ranges for women and men. Before the menopause, women tend to have slightly lower blood pressure than men of the same age; after the menopause, the difference narrows. High blood pressure in pregnancy is assessed differently and is checked at every antenatal appointment.
Frequently asked questions
What is normal blood pressure for a 70 year old?
The ideal range is the same as for younger adults: 90/60 to 120/80. High blood pressure is 140/90 or more. If you are being treated, the clinic target is below 140/90.
What is normal blood pressure for an 80 year old?
Ideal is still 90/60 to 120/80, but for people aged 80 and over, high blood pressure is defined as 150/90 or more, and the treatment target is below 150/90.
Does blood pressure go up with age?
Systolic blood pressure usually rises with age because arteries become stiffer. It is common but should still be checked and treated if high.
Is 140/80 OK for a 75 year old?
A systolic reading of 140 is at the threshold for high blood pressure for people under 80. It should be checked again, ideally with home readings, and discussed with your GP.
