What Is the Normal Blood Pressure for Each Age?
There isn’t a separate “normal” blood-pressure number for every age. For adults, blood-pressure categories are generally based on the reading itself, although an individual’s treatment goal may be adjusted according to age, health, and other medical conditions.
Adults
| Category | Top number (systolic) | Bottom number (diastolic) |
|---|---|---|
| Normal | <120 | and <80 mmHg |
| Elevated | 120–129 | and <80 |
| High BP — Stage 1 | 130–139 | or 80–89 |
| High BP — Stage 2 | ≥140 | or ≥90 |
| Severely high | >180 | and/or >120 |
A reading such as 135/85 is not “normal because you’re over 65.” It falls into a high-blood-pressure category under these criteria. However, diagnosis should generally be based on repeated measurements rather than one isolated reading.
👶 Children and teenagers
Children are different. Their blood pressure is interpreted using age, sex, and height, rather than the adult table. A pediatric healthcare professional should interpret a child’s reading.
👵 What about people over 70?
Age can affect what treatment target is appropriate, but high blood pressure isn’t simply considered normal because someone is older. Doctors may individualize treatment based on frailty, other illnesses, medications, dizziness, and risk of falls.
How to measure it correctly
For a more reliable home reading:
- Sit quietly for about 5 minutes beforehand.
- Keep your back supported and feet flat on the floor.
- Rest your arm on a surface at heart level.
- Don’t measure immediately after exercise, smoking, or caffeine.
- Take two readings about one minute apart and record them.
🚨 When it’s an emergency
If your reading is over 180/120 mmHg, repeat it after at least one minute. If it remains that high, contact a healthcare professional promptly.
If you also have chest pain, difficulty breathing, weakness or numbness, vision changes, difficulty speaking, severe headache, or confusion, seek emergency medical care immediately.
If you give me your age and your blood-pressure reading, such as “72 years old, 148/88,” I can explain what that specific reading means.
