Here’s a general guide:
| Age | Normal blood pressure |
|---|---|
| 18–39 years | Less than 120/80 mmHg |
| 40–59 years | Less than 120/80 mmHg |
| 60 years and older | Less than 120/80 mmHg (treatment goals may be individualized) |
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 or | 80–89 |
| High blood pressure (Stage 2) | 140 or higher or | 90 or higher |
| Hypertensive crisis | 180 or higher and/or | 120 or higher |
Why age still matters
As people get older, blood pressure tends to rise because arteries become less elastic. Even so, healthcare professionals generally aim to keep blood pressure below 130/80 mmHg for many adults if it can be achieved safely. For some older adults—especially those who are frail or have multiple medical conditions—the target may be adjusted based on individual circumstances.
Tips for accurate measurement
- Rest quietly for 5 minutes before measuring.
- Sit with your back supported and feet flat on the floor.
- Keep your arm supported at heart level.
- Avoid caffeine, smoking, or exercise for at least 30 minutes beforehand.
- Take two readings, 1–2 minutes apart, and average them.
When to seek urgent care
If your blood pressure is 180/120 mmHg or higher and you have symptoms such as chest pain, shortness of breath, severe headache, vision changes, confusion, or weakness, seek emergency medical care immediately.
If you’d like, I can also explain what blood pressure is considered normal for children and teenagers, since their healthy ranges do vary by age, sex, and height.
