Blood pressure doesn’t have a completely different “normal” value for every age. For most adults, doctors use the same general categories regardless of age.
Adult Blood Pressure Categories
| Category | Systolic (top number) | Diastolic (bottom number) |
|---|---|---|
| Normal | Less than 120 | Less than 80 |
| Elevated | 120–129 | Less than 80 |
| High Blood Pressure (Stage 1) | 130–139 | 80–89 |
| High Blood Pressure (Stage 2) | 140 or higher | 90 or higher |
| Hypertensive Crisis* | 180 or higher | 120 or higher |
*Seek immediate medical attention if accompanied by symptoms such as chest pain, shortness of breath, severe headache, weakness, or vision changes.
Typical Ranges by Age (Not Strict Targets)
While the definition of “normal” doesn’t change much with age, average blood pressure tends to rise somewhat over time:
| Age Group | Typical Healthy Range |
|---|---|
| 18–39 years | Around 90/60 to 120/80 |
| 40–59 years | Usually below 130/80 |
| 60+ years | Often below 130/80 is still a common goal, depending on health status |
When Blood Pressure May Be Too Low
Blood pressure below 90/60 mmHg is often considered low, but it is only a concern if it causes symptoms such as:
- Dizziness
- Fainting
- Weakness
- Blurred vision
Warning Signs That Need Medical Attention
Seek prompt medical care if high blood pressure is accompanied by:
- Severe headache
- Chest pain
- Shortness of breath
- Sudden weakness or numbness
- Difficulty speaking
- Vision loss
These can be signs of serious conditions including a Stroke.
Bottom line
For most adults, a blood pressure below 120/80 mmHg is considered normal, and 130/80 mmHg or higher may indicate high blood pressure. Individual targets can vary based on age, medical conditions, and a doctor’s recommendations.
