Blood Pressure Chart by Age: Normal Readings and Why Targets Stay Put

There is no separate "normal blood pressure by age" chart for adults. The healthy range is the same at 30 as it is at 70: below 120/80 mmHg is normal, and 130/80 or higher counts as high blood pressure for every adult. Average readings do tend to climb with age, but that is a description of a common problem, not a higher target you are allowed to hit.

The age charts you find online usually blur two different things. One is what a healthy blood pressure is, which the American Heart Association fixes with the same category cut-offs for all adults. The other is what blood pressure people of a given age typically have, which really does rise, mostly on the systolic (top) side, as arteries stiffen with age. When a chart lists "125/82 as normal for your 60s," it has quietly swapped the second idea in for the first. The 2017 guideline that moved the high blood pressure line down to 130/80 applies to everyone, so a reading that a 20-year-old chart called fine may sit in the stage 1 range today.

Why adults don't get an age-adjusted target

Before 2017, some rules of thumb did loosen the numbers for older adults. The ACC/AHA guideline dropped that approach in 2017, and its 2025 update kept it that way, because the risk from higher pressure doesn't take a break as you get older. Harvard Health sums up the shift plainly: 130 is the new 140, and the threshold holds across age groups rather than sliding up decade by decade. Higher blood pressure raises the risk of stroke and heart disease at 70 just as it does at 40, so the goalposts stay put.

That is why "normal for my age" is a phrase worth retiring. If your reading is 138/85, it doesn't become healthy because a chart labeled it typical for someone in their 60s. It is stage 1 either way, and the useful response is the same at any age: confirm it with a few careful home readings and talk to a clinician about it.

The categories that apply at every adult age

These are the ranges from the American Heart Association and echoed on the Mayo Clinic blood pressure chart. They do not change with age.

A reading in the crisis row is the one exception that can't wait. If you get a number above 180/120, wait at least 1 minute and measure again. If it stays that high and you have no symptoms, the AHA calls it severe hypertension: contact your healthcare professional as soon as possible. If you have chest pain, shortness of breath, back pain, numbness, weakness, vision changes or trouble speaking, it is a hypertensive emergency: call emergency services. Our full walkthrough of what your blood pressure numbers mean unpacks each category in more detail.

What actually changes with age

Something real does happen to blood pressure over the decades, and it is worth understanding so you know what your own trend is telling you. According to a physiology review from the NIH's StatPearls, arteries lose elasticity and stiffen as we age. That stiffening pushes the systolic number up fairly steadily into the seventies and eighties. The diastolic number behaves differently: it tends to rise until about age 50, then flattens out or even drifts down.

Here is what that looks like in real numbers. These are the average readings measured in a large US national health survey (NHANES, 2001–2008), as reported by the CDC's National Center for Health Statistics. They include people with treated and untreated high blood pressure, so they show what is common, not what is healthy.

Read this table as typical, not as a target. The healthy range is still below 120/80 at every age, and the average for adults aged 60 and over, 136/68, already falls in Stage 1 on the systolic side. Notice also how the top number keeps climbing while the bottom number drops back after midlife: that is the widening gap described next.

The practical result is a widening gap between the two numbers, which is your pulse pressure. A reading like 145/70 in an older adult is a common shape, and that wide gap is itself a marker of stiffer arteries rather than a harmless quirk of age. If you want the detail on that gap, our post on what pulse pressure means covers it. None of this makes a high reading acceptable. It explains why hitting the target can take more effort later in life, not that the target has moved.

Blood pressure in children and teens

Kids are the one group where age genuinely drives the numbers. For children and adolescents, "normal" isn't a single figure at all. It is defined by percentiles for a child's age, sex and height, because a healthy reading for a small six-year-old is different from one for a tall fifteen-year-old. The fixed adult categories above only start to apply in the later teen years. Pediatric readings are interpreted by a clinician against those percentile charts, so an age-and-height context is doing the work that a single adult threshold does for grown-ups.

What to do with your own numbers over time

Because average blood pressure drifts up with age, your own trend line matters more than any one reading measured against a chart. The reliable figure is an average of readings taken the same way over several days, not a single number caught on a stressful morning. The AHA recommends taking two or three readings a minute apart, morning and evening, and averaging them. Take them seated, arm at heart level, after five minutes of rest, using the same arm each time. Our checklist for an accurate reading at home covers the setup.

This is where BPlus fits in. You log each systolic, diastolic and pulse value by hand, or scan your monitor's display with the camera so the numbers go in without typing, and the time, date and arm are stamped for you. BPlus sorts each reading into the same five categories shown above, charts your trend so you can see whether the average is creeping up year over year, and exports a doctor-ready PDF or CSV for your next visit. It keeps everything on your device, works offline and needs no account. BPlus is a wellness and logging tool: it does not measure, diagnose or treat blood pressure, and it is not a substitute for professional care. What it does is turn scattered readings into a trend you and your clinician can actually read, which is exactly what a moving target with age calls for.

Mini-FAQ

Is 120/80 normal for a 70-year-old? Not quite. Under the ACC/AHA categories used in this article, normal means below 120 systolic and below 80 diastolic, so a bottom number of exactly 80 already counts as Stage 1. European and UK guidelines (ESH, NICE) would still call 120/80 normal. Either way, the answer is the same at 70 as at 25: adult categories are not age-adjusted, and average readings rise with age while the healthy range does not.

What is a good blood pressure by age? The same at every adult age: below 120/80 mmHg is normal, and the aim is to stay under 130/80. Charts that list higher "normal" numbers for older decades are showing typical readings, not healthy targets. There is no age at which a higher number becomes safe.

Why does blood pressure go up as you get older? Arteries stiffen and lose elasticity with age, which raises the systolic (top) number in particular. The NIH notes systolic pressure tends to climb into the seventies while diastolic often plateaus after about 50. That is why hitting the target can take more effort later, not that the target changes.

Does normal blood pressure differ for men and women? The categories are the same for both. Some average readings differ slightly by sex across the lifespan, but the thresholds used to define normal, elevated and high blood pressure do not change for men versus women.
