A common misconception is that there is a different “normal” blood pressure for every age. For most adults, the same general blood pressure ranges apply regardless of age. While blood pressure tends to rise with age, higher values are not considered normal just because someone is older.
Blood pressure categories for adults (18 years and older)
| 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 |
*A reading this high requires prompt medical assessment, especially if accompanied by symptoms such as chest pain, shortness of breath, severe headache, confusion, vision changes, or weakness.
What about children?
Normal blood pressure in children does vary by age, sex, and height, so pediatric healthcare professionals use specialized charts rather than one set of numbers.
Tips for getting an accurate reading
- Rest quietly for at least 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, and exercise for about 30 minutes beforehand if possible.
- Take two readings, 1–2 minutes apart, and average them.
A single high reading does not necessarily mean you have high blood pressure. Diagnosis usually requires repeated measurements taken on different days or with home or ambulatory blood pressure monitoring.
If you tell me your age and your recent blood pressure reading (for example, 128/78 mmHg), I can help explain what it means.
