Blood Pressure by Age: What’s a Healthy Reading and How to Protect Your Heart
Blood pressure is one of the most important vital signs for assessing cardiovascular health. While the “ideal” reading is often cited as 120/80 mmHg, what’s considered healthy can vary depending on age, individual health, medications, and other factors.
This guide breaks down common blood pressure categories and offers practical tips for maintaining healthy blood pressure at different stages of life.
Important: Blood pressure information can vary between guidelines, and a single reading does not diagnose hypertension. Your healthcare professional can interpret your readings in the context of your overall health.
Blood Pressure Categories for Adults
According to the American Heart Association (AHA) and commonly used U.S. guidelines:
| Category | Systolic (Top Number) | Diastolic (Bottom Number) |
|---|---|---|
| Normal | < 120 mmHg | and < 80 mmHg |
| Elevated | 120–129 mmHg | and < 80 mmHg |
| Hypertension Stage 1 | 130–139 mmHg | or 80–89 mmHg |
| Hypertension Stage 2 | ≥ 140 mmHg | or ≥ 90 mmHg |
| Hypertensive Crisis | > 180 mmHg | and/or > 120 mmHg |
Systolic blood pressure is the pressure in your arteries when your heart contracts.
Diastolic blood pressure is the pressure when your heart relaxes between beats.
Under these guidelines, blood pressure of 130/80 mmHg or higher falls within the hypertension range, although diagnosis should be based on appropriate measurements rather than one isolated reading.
Blood Pressure in Children and Teens
Blood pressure assessment is different for younger people.
For children and adolescents, healthcare professionals consider factors such as age, height, and sex, rather than simply applying adult blood-pressure categories.
Approximate ranges sometimes used for general reference include:
| Age Group | Approximate Systolic | Approximate Diastolic |
|---|---|---|
| 1–3 years | 80–110 mmHg | 50–70 mmHg |
| 4–6 years | 85–115 mmHg | 55–75 mmHg |
| 7–10 years | 90–120 mmHg | 60–80 mmHg |
| 11–13 years | 95–125 mmHg | 60–80 mmHg |
| 14–18 years | 100–135 mmHg | 65–85 mmHg |
These numbers are general reference ranges, not diagnostic targets.
A child’s blood pressure should be interpreted using pediatric standards and growth measurements. If a child’s reading repeatedly appears high, a pediatric healthcare professional should evaluate it.
