Blood pressure: normal range and 2025 US and ESC targets
In the US, the 2025 AHA/ACC guideline defines normal blood pressure as below 120/80 mmHg, elevated as 120 to 129 systolic with a diastolic below 80, and hypertension from 130/80 mmHg. On treatment, the goal is below 130/80 mmHg, with encouragement to reach a systolic below 120. European and UK thresholds differ.
A reading of 130 or 135 mmHg at the doctor's office is often met with a shrug. Yet in the US it already counts as stage 1 hypertension, while in Europe or the UK the same number would not be called hypertension. This guide explains these numbers, why they differ, how to measure your blood pressure properly at home and what actually brings it down.
What do the two blood pressure numbers mean?
Blood pressure is expressed as two numbers, in millimeters of mercury (mmHg):
- systolic pressure, the first number, is the pressure in the arteries when the heart contracts;
- diastolic pressure, the second number, is the pressure when the heart relaxes between two beats.
Pressure that stays too high for years gradually damages the walls of the arteries, the heart, kidneys, brain and eyes, usually without causing any symptom. That is why hypertension is called the "silent killer". According to the CDC, 48.1% of US adults, about 120 million people, have high blood pressure, about 1 in 4 of them have it under control, and about 1 in 6 are unaware of it. Worldwide, the World Health Organization (WHO) estimates that 1.4 billion adults aged 30 to 79 had hypertension in 2024, and about 23% had it under control.
Normal, elevated and high blood pressure: US and European thresholds
The 2025 AHA/ACC guideline kept the categories of 2017. They are based on office readings:
| Category (AHA/ACC 2025) | Systolic | | Diastolic | |---|---|---|---| | Normal | below 120 mmHg | and | below 80 mmHg | | Elevated | 120 to 129 mmHg | and | below 80 mmHg | | Stage 1 hypertension | 130 to 139 mmHg | or | 80 to 89 mmHg | | Stage 2 hypertension | 140 mmHg or more | or | 90 mmHg or more |
The same reading can carry a different name elsewhere. These differences change how a number is read:
- Europe: the 2024 ESC guidelines call below 120/70 mmHg non-elevated, 120 to 139 systolic or 70 to 89 diastolic elevated, and 140/90 mmHg or more hypertension.
- UK: NICE diagnoses hypertension from a clinic reading of 140/90 mmHg or more, confirmed by an average of 135/85 mmHg or more outside the clinic.
All agree on the underlying point: cardiovascular risk rises gradually, with no sudden step at one number.
Readings above 180/120 mmHg are dangerously high and need immediate medical attention. With a severe headache, chest pain, shortness of breath, visual disturbances or weakness on one side of the body, call 911.
Elevated blood pressure: when is treatment needed?
Being in the elevated category does not mean taking a medicine. The 2025 AHA/ACC guideline recommends lifestyle changes first. For hypertension, the decision depends on your overall risk:
- Medication is recommended from 130/80 mmHg if you have cardiovascular disease, diabetes or chronic kidney disease, or a 10-year risk of 7.5% or more with the PREVENT equations.
- With a lower risk, medication is recommended if blood pressure stays at 130/80 mmHg or more after 3 to 6 months of lifestyle changes.
- For stage 2 hypertension, the guideline favors starting with two medicines of different classes, preferably in a single pill.
The USPSTF does not set treatment thresholds, but it recommends screening for hypertension in all adults from age 18 (grade A, 2021). The 2024 ESC guidelines are more cautious: about 3 months of lifestyle changes, then treatment only if systolic pressure remains at 130 to 139 mmHg and cardiovascular risk is high.
A history of pregnancy complications (preeclampsia, gestational hypertension) directly concerns many women: even long ago, it is worth reminding your doctor about. To understand how this overall risk is calculated, read our article on integrated cardiovascular prevention.
Blood pressure target on treatment: below 130/80 mmHg
For most adults on treatment, the 2025 AHA/ACC guideline sets a goal below 130/80 mmHg, with encouragement to reach a systolic below 120 mmHg when feasible. Each 10 mmHg reduction in systolic pressure is associated with about 20% fewer major cardiovascular events.
Elsewhere, the 2024 ESC guidelines aim for a systolic of 120 to 129 mmHg if well tolerated. NICE in the UK aims for a clinic reading below 140/90 mmHg before age 80.
The goal is adapted to each person. The US guideline makes exceptions for people in institutional care or with limited life expectancy, and for pregnancy. European guidelines allow a more flexible approach, "as low as reasonably achievable", in case of very old age, frailty, symptomatic orthostatic hypotension (dizziness on standing up) or poor tolerance.
The choice of goal and treatment rests with the doctor. If you feel dizzy, very tired or faint after a change in treatment, report it rather than stopping on your own.
Measuring blood pressure at home
A single office reading is unreliable. Some people have higher blood pressure at the doctor's than at home (the "white coat" effect, which the CDC says may concern as many as 1 in 3 people with a high office reading), others the opposite: normal pressure in the office but high in daily life ("masked" hypertension). The USPSTF and the 2025 AHA/ACC guideline therefore support confirming the diagnosis with measurements outside the office.
How often to check your blood pressure at home
Your doctor will tell you the schedule to follow. The CDC suggests measuring at the same time each day and taking at least two readings, 1 or 2 minutes apart. Writing them in a log gives your doctor an average to read, which says more than any single value.
How to take your blood pressure correctly at home
- Use a validated device with an upper-arm cuff, sized to your arm. The 2025 AHA/ACC guideline recommends against cuffless devices for diagnosis or treatment decisions.
- Empty your bladder, sit with your back supported for at least 5 minutes, feet flat, arm resting on a table with the cuff at heart level, without talking.
- Avoid eating, drinking, caffeine, smoking and exercise in the 30 minutes before.
- Write down every value, even those that seem "bad".
With home monitoring, the thresholds also differ. In the US, an average of 130/80 mmHg or more points to hypertension, the same as in the office. European and UK guidelines use 135/85 mmHg. A normal home average with high readings at the doctor's suggests a white coat effect, which still deserves follow-up.
Ambulatory monitoring: blood pressure over 24 hours
Ambulatory blood pressure monitoring (ABPM) automatically records blood pressure every 20 to 30 minutes over 12 to 24 hours, usually including the night. It is useful when home monitoring is difficult, when results are inconsistent, or to check that blood pressure drops properly during sleep. Hypertension thresholds with ABPM are:
| Period | US (AHA/ACC 2025) | Europe (ESC 2024) | |---|---|---| | 24-hour average | 125/75 mmHg or more | 130/80 mmHg or more | | Daytime average | 130/80 mmHg or more | 135/85 mmHg or more |
Nighttime readings are normally lower: the 2024 ESC guidelines set their nighttime threshold at 120/70 mmHg or more.
Blood pressure that does not fall at night may point to a sleep disorder, particularly sleep apnea. Our article on sleep and inflammation explains this link.
The levers that lower blood pressure
Lifestyle measures are not a "small extra": each can lower systolic pressure by several mmHg, and their effects add up. The 2025 AHA/ACC guideline strongly recommends them for everyone with elevated blood pressure or hypertension:
- Salt: the Dietary Guidelines for Americans set sodium below 2,300 mg per day from age 14. Sodium comes mainly from packaged and restaurant foods, far more than from the salt shaker.
- DASH-style eating: more vegetables, fruit, whole grains, beans and nuts, less saturated fat and added sugar. Potassium-based salt substitutes may help some people, but need medical advice in advanced kidney disease.
- Weight: losing some weight is often enough to lower blood pressure.
- Physical activity: at least 150 minutes per week of moderate activity (brisk walking, cycling), plus muscle strengthening at least 2 days a week. See what 150 minutes of activity change in your blood tests.
- Alcohol: reduce it. The CDC describes moderate drinking as two drinks or less in a day for men and one or less for women. Our article on alcohol, tobacco and blood tests gives the benchmarks.
- Tobacco: quitting does not necessarily lower blood pressure, but it sharply reduces overall cardiovascular risk.
- Stress and sleep: manage stress and get enough good-quality sleep.
Some medicines and products also raise blood pressure: NSAID pain relievers (such as ibuprofen), nasal decongestants, some combined hormonal contraceptives, large amounts of licorice. Talk to your doctor or pharmacist.
Hypertension: what blood tests add
Blood pressure is not measured in the blood, but blood tests help assess its impact and overall risk. When hypertension is first found, testing usually includes creatinine with an estimate of glomerular filtration rate (eGFR), potassium and sodium, fasting glucose, a lipid panel, and an electrocardiogram. The 2025 AHA/ACC guideline adds a urine albumin-to-creatinine ratio. It also widens testing for primary aldosteronism, a hormonal cause: testing is recommended in resistant hypertension, even with normal potassium, and may be considered in stage 2 hypertension. Potassium and creatinine are also monitored on treatment. For kidney function, read our guide to creatinine and eGFR.
Frequently asked questions
My blood pressure is 130/80: should I worry?
No, but it deserves attention. In the US, 130/80 mmHg falls in stage 1 hypertension, while the 2024 ESC guidelines call it elevated. This is the time to act on salt, activity and weight, and to check your numbers with home monitoring. Treatment depends on your overall cardiovascular risk.
What is normal blood pressure by age?
The AHA/ACC categories are the same for all adults, whatever their age. What adapts is the goal on treatment, which is more flexible with frailty, limited life expectancy or poor tolerance. The doctor sets it case by case.
How often should blood pressure be checked?
The USPSTF considers yearly screening reasonable from age 40 or in people at increased risk, and every 3 to 5 years between 18 and 39 after a normal reading. A validated home monitor makes follow-up easier.
Does stress raise blood pressure?
Temporarily, yes: stress, pain or rushing to arrive on time can push the numbers up. That is why a single reading is not enough and the home monitoring average is what counts.
Is low blood pressure a problem?
Low blood pressure without symptoms is not a disease. Dizziness on standing, fainting or falls, however, should be reported, especially on treatment.
