What Is a Normal Blood Pressure by Age?
People often ask what blood pressure is "normal for their age" — expecting the healthy range to climb as they get older. It's a reasonable assumption, but it's mostly a myth. The target for a healthy adult is roughly the same at 30 as it is at 70. What changes with age is the average reading — and that's a reflection of how common high blood pressure becomes, not a higher bar you're allowed to hit.

Reading the two numbers
Blood pressure is written as two numbers — for example, 118/76 mmHg, said aloud as "118 over 76."
- Systolic (top number) is the pressure in your arteries when your heart beats and pushes blood out. It's the number that tends to matter most for adults over 50.
- Diastolic (bottom number) is the pressure between beats, when your heart is at rest and refilling.
Both are measured in millimeters of mercury (mmHg), a unit left over from the original mercury-column gauges. A single high reading doesn't equal high blood pressure — diagnosis is based on the average of multiple readings taken on separate occasions, ideally while seated, rested, and calm.
The blood pressure categories (AHA)
The American Heart Association (AHA) and American College of Cardiology define five categories. These apply to adults of all ages — there is no separate, more lenient chart for older people.
| Category | Systolic | Diastolic | |
|---|---|---|---|
| Normal | Less than 120 | and | Less than 80 |
| Elevated | 120–129 | and | Less than 80 |
| Hypertension Stage 1 | 130–139 | or | 80–89 |
| Hypertension Stage 2 | 140 or higher | or | 90 or higher |
| Hypertensive crisis | Higher than 180 | and/or | Higher than 120 |
A hypertensive crisis (above 180/120) with symptoms such as chest pain, shortness of breath, or vision changes is a medical emergency — call emergency services rather than waiting.
Average blood pressure by age
Here's where age genuinely comes in. The table below shows typical readings observed across age groups. These are averages from population data — descriptions of what's common, not targets to aim for. The healthy goal for nearly every adult remains under 120/80.
| Age range | Typical (men) | Typical (women) |
|---|---|---|
| 18–29 | 119/70 | 110/68 |
| 30–39 | 122/76 | 114/71 |
| 40–49 | 126/79 | 120/75 |
| 50–59 | 129/80 | 127/78 |
| 60–69 | 133/80 | 133/80 |
| 70+ | 139/79 | 141/80 |
Notice two patterns: systolic pressure drifts upward with age as arteries stiffen, and women — who generally start lower than men — tend to catch up and even surpass men after menopause. By the 70s, the "average" reading sits in the Stage 1 hypertension range. That tells you how widespread high blood pressure is in older adults, not that 139/79 is healthy.
Why average isn't the same as healthy
This is the key distinction. Roughly half of US adults have blood pressure above the normal range, and that share rises steeply with age — well over half of people in their 60s and beyond. Because so many people are affected, the statistical average lands inside the elevated or hypertensive zone.
If you adopted the "normal for my age" reasoning, you'd treat a steadily rising reading as fine simply because your peers share it. But the cardiovascular risk is real regardless of how common it is. Large studies, including SPRINT, found that intensively lowering systolic pressure toward 120 reduced heart attacks, heart failure, and deaths even in adults over 75. Lower — within reason and under medical guidance — is generally better at every age.
Special cases worth knowing
- Children and teens. Blood pressure norms for under-18s are based on percentiles for age, sex, and height — the adult chart doesn't apply. A pediatrician interprets these.
- Isolated systolic hypertension. In older adults the top number can be high (say 150) while the bottom stays normal (say 75). This is the most common form of high blood pressure after 65 and still warrants treatment.
- Low blood pressure. Readings under about 90/60 (hypotension) can cause dizziness or fainting, especially when standing up quickly. It matters most when it produces symptoms.
- White-coat and masked hypertension. Some people read high only at the clinic; others read normal at the clinic but high at home. Home monitoring helps reveal your true baseline.
How to keep blood pressure in a healthy range
Lifestyle changes can lower systolic pressure by 5–10 mmHg each — together often as much as a medication.
- Cut sodium, raise potassium. Staying under 1,500–2,300 mg of sodium a day while eating more vegetables, fruit, and legumes (the DASH pattern) has the strongest dietary effect.
- Move regularly. About 150 minutes a week of moderate activity — brisk walking counts — meaningfully lowers pressure.
- Manage weight. Each kilogram lost trims roughly 1 mmHg off systolic pressure for people carrying excess weight. Our BMI calculator and waist-to-hip ratio calculator can help you track this.
- Limit alcohol and don't smoke. Both raise pressure; smoking also stiffens arteries over time.
- Sleep and stress. Poor sleep and chronic stress keep pressure elevated. Treating sleep apnea, in particular, can produce a notable drop.
