What is normal blood pressure for women?
Normal blood pressure for women is under 120/80 mm Hg, and 130/80 or above counts as high in the US, while the UK draws the line at 140/90 in clinic (135/85 at home). Blood pressure is one of the routine health checks for women, and knowing where the lines sit makes your own reading much easier to understand.
If the two numbers on a blood pressure reading have ever felt like a code, that is common, and they are simpler than they look. Blood pressure is the force of blood against your artery walls, written in millimeters of mercury (mm Hg). The top number, systolic, is the pressure as the heart beats. The bottom number, diastolic, is the pressure between beats. Two other lines are worth knowing. The NHS counts a reading below 90/60 as low, which can be simply how a fit or naturally low-running body works, and can also come with pregnancy, getting older or certain medicines. In pregnancy, the CDC puts high blood pressure at 140/90 or above.
What is the normal blood pressure range for women?
The normal blood pressure range for women is a reading below 120 systolic and below 80 diastolic, and above the 90/60 line where low blood pressure begins. The US categories, set by the American College of Cardiology and American Heart Association and summarized by the CDC, step up in three stages. Elevated is 120–129 with a diastolic under 80. Stage 1 is 130–139 or 80–89. Stage 2 is 140 or higher or 90 or higher.
For stage 1 and stage 2, either number is enough to place a reading in the category. The CDC gives these categories for adults as a whole, so an average or good blood pressure range for women is read from the same chart as everyone else's. They describe steps along a scale, not one ideal number to hit.
What does the evidence say about women's blood pressure?
About 42.1% of US adult women have high blood pressure, according to the CDC, compared with 50% of men. A raised reading is therefore common, and nothing to feel alone with. The CDC also reports that only 22.5% of US adults with high blood pressure, about 1 in 4, have it under control, which is where regular checks come in.
The US Preventive Services Task Force (USPSTF) recommends blood pressure screening for all adults aged 18 and over, a Grade A recommendation in its 2021 statement. It is worth asking for the two numbers themselves, not only whether they were fine.
Pregnancy is when blood pressure is watched most closely. Preeclampsia (pre-eclampsia in the UK), a pregnancy condition involving high blood pressure, occurs in about 2–8% of pregnancies, according to the CDC.
For the other number often checked at the same visit, our guide to high cholesterol symptoms in women is for readers who want that side too.
How often should women have their blood pressure checked?
The USPSTF suggests a check every 3–5 years for women aged 18–39 who are at low risk and have had a normal reading before, and a yearly check from age 40 or when risk is higher. A yearly check also applies if a reading has been raised or if you are pregnant, and in pregnancy blood pressure is checked at every prenatal appointment (antenatal in the UK).
A home monitor is useful between visits, and many women bring their home readings along, which gives a primary care provider or GP more than one number to look at.
A reading is a routine part of a well woman exam, a convenient moment to ask which category your numbers fall in.
What do the guidelines agree on, and where do they differ?
Expert groups agree that screening adults is well supported, and they draw the line for high blood pressure in slightly different places. The USPSTF notes that organizations' thresholds range from 130/80 to 140/90, and the US and UK figures sit at the two ends of that range. A reading between the two is a good one to talk through with a primary care provider or GP.
Treatment targets differ in the same way. The 2025 high blood pressure guideline from the American Heart Association and American College of Cardiology sets a goal of under 130/80 for most adults, with an emphasis on prevention and early treatment, while UK guidance works to 140/90, or 150/90 for people over 80.
The national figures have limits too. The 42.1% prevalence figure is for US women, so it does not describe the UK, and the 22.5% control figure covers US adults as a whole, not women alone.
Blood pressure by life stage
| Stage | Figure | Why | Read more |
|---|---|---|---|
| Childhood | No adult figure applies: the ranges and screening schedule on this page are for adults aged 18 and over. | The USPSTF screening recommendation starts at 18, so a child's reading is one to talk through with her own doctor. | Health checks |
| Puberty | Adult screening begins at 18 (USPSTF); the categories on this page are written for adults. | For a teenager's reading, her own doctor is the person to ask what it means. | Health checks |
| Reproductive years | Every 3–5 years under 40; yearly from 40, if raised or if pregnant. Under 120/80 normal, 130/80 or above high (US); UK threshold: 140/90. | Checked at every antenatal appointment. | Health checks |
| Perimenopause | At least yearly. Under 120/80 normal, 130/80 or above high (US); UK threshold: 140/90. | A home monitor is useful. | Health checks |
| Menopause | At least yearly. Under 120/80 normal, 130/80 or above high (US); UK threshold: 140/90. | A home monitor is useful. | Health checks |
| Postmenopause | At least yearly. Under 130/80 for most adults (US); UK targets 140/90, or 150/90 over 80. | The US figure at this stage is a treatment goal; a home monitor is useful. | Health checks |

Facts
Common questions
What is considered high blood pressure in women?
In the US, 130/80 or above is considered high, and in the UK the line is 140/90. One raised clinic reading is a prompt to measure again, not a diagnosis: the USPSTF advises confirming with readings taken outside the office, such as at home. A primary care provider or GP can talk through next steps.
What is considered high blood pressure in pregnant women?
In pregnancy, high blood pressure is diagnosed at 140/90 or above on two readings at least 4 hours apart, and 160/110 or above is classed as severe, according to the CDC. Because the diagnosis rests on two readings, a single high number is a reason to ask your OB-GYN or midwife for a repeat rather than to wait for the next appointment.
How to lower blood pressure for pregnant women?
Plan this with your OB-GYN or midwife, who can decide on any medicines with you. The 2025 AHA/ACC guideline suggests women with high blood pressure who are pregnant or planning a pregnancy discuss low-dose aspirin, 81 mg a day, to lower preeclampsia risk. Bringing recent readings is a good place to start.
What causes low blood pressure in women?
The NHS lists several causes of low blood pressure (hypotension): being naturally low or fit, an inherited tendency, getting older, pregnancy, conditions such as diabetes and certain medicines. If low readings bother you, a note of when they happen and which medicines you take gives a primary care provider or GP a clear place to start.
Can blood pressure rise after the baby is born?
Yes, it can. The CDC notes that postpartum preeclampsia usually appears within 48 hours of birth, and can occur up to 6 weeks later. It is worth keeping an eye on readings through those weeks, and mentioning any concern promptly to your midwife, OB-GYN or GP.
How much salt is suggested for healthy blood pressure?
The 2025 AHA/ACC guideline points to under 2,300 mg of sodium a day, about 1 teaspoon of salt. If your blood pressure is raised, you might ask your primary care provider or GP whether a personal sodium target would suit you better.
Next steps
A good place to start is your most recent reading: if you cannot recall the two numbers, you might ask for them at your next visit. If you are pregnant or planning a pregnancy, your OB-GYN or midwife is the person to bring readings to, and a pregnancy reading in the severe range is worth raising right away rather than at the next appointment. Outside pregnancy, symptoms that are getting worse are a reason to see a doctor sooner than your next routine check. Blood pressure is not one size fits all: the same reading can sit under the UK line and over the US one, so how often you check and which target you work toward are yours to decide, with your provider.
