120, 140, or 150? Why your target blood pressure numbers keep changing

Anyone who measures their blood pressure at home has probably seen headlines saying the ideal number has changed. They largely trace back to a 2024 guideline from the European Society of Cardiology (ESC).

But that doesn’t mean your doctor is wrong if they mention 130, 140, or even 150.

What European cardiologists changed

The ESC's 2024 guidance introduced a more ambitious treatment target: 120-129 mmHg systolic and 70-79 mmHg diastolic for adults receiving treatment, where that level is well tolerated. The ESC still defines hypertension in the doctor's office as 140/90 or higher, but it also introduced an “elevated blood pressure” category covering systolic readings from 120 to 139 or diastolic readings from 70 to 89.

That distinction matters because a number can be high enough to deserve attention without automatically meaning that everyone with that reading needs medication.

The ESC also stresses that the lower target isn't suitable for everybody. Frailty, symptoms and a person's ability to tolerate treatment all matter.

National guidelines still differ, and your age, general health and even where your blood pressure was measured can change the number doctors use.

The UK and US use different numbers

In Britain, the current recommendation is a clinic blood pressure below 140/90 for adults under 80 with uncomplicated hypertension. For people aged 80 and over, the usual clinic target is below 150/90, although individual circumstances such as frailty and other illnesses should be considered.

The United States goes lower. Updated 2025 guidance sets an overall treatment goal below 130/80 mmHg for adults, while allowing additional considerations for people whose circumstances make that target less straightforward.

That means two doctors in different countries can give different target numbers without either necessarily being “behind” on the science.

Dutch GPs may still talk about 140 or 150

Dutch primary-care guidance takes a different approach. Current cardiovascular-risk guidance generally uses a systolic target below 140 mmHg for people aged 70 and younger. A target below 130 may be considered when treatment is well tolerated, particularly for people at higher cardiovascular risk.

For older adults who are still relatively fit, the general target is below 150, with further lowering toward 140 considered when appropriate. For frail older adults, the guidance also uses a target below 150 and recommends cautious treatment, including avoiding an excessively low diastolic pressure.

So reaching your 70s does not automatically trigger one new “correct” number. How fit or frail you are can matter as much as your birthday.

Why 135 at home can mean something different

There's another complication: where you take the measurement matters.

Blood pressure measured at home is generally lower than a clinic reading. NICE, for example, uses home or ambulatory treatment targets below 135/85 for people under 80 and below 145/85 for people aged 80 and over.

The guidance also distinguishes between measuring methods. A clinic systolic reading of 140 roughly corresponds to about 135 with a structured home measurement and around 130 on a 24-hour monitor.

So comparing a home reading directly with a headline about clinic blood pressure can be misleading.

Three questions worth asking at your next check-up

Rather than chasing one universal number, ask your doctor: What target applies to me, and why? Is my home-monitor target different from my clinic target? And do symptoms such as dizziness when standing mean my goal should be adjusted?

Those questions become especially important as you get older, because all guidance emphasizes whether lower blood pressure is actually tolerated.

Most importantly, don't increase, reduce, or stop blood pressure medication because a new headline gives a different target. Take your home readings to your doctor and discuss which target makes sense for you.
