There isn’t a different “normal” blood pressure for each age. For most adults, the same blood pressure categories apply regardless of age.
Here are the commonly used categories:
| Category | Systolic (top number) | Diastolic (bottom number) |
|---|---|---|
| Normal | Less than 120 | and less than 80 |
| Elevated | 120–129 | and 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 (seek immediate medical care) |
What about age?
Blood pressure tends to increase with age, but higher blood pressure is not considered “normal” just because someone is older. Healthcare providers often individualize treatment goals based on a person’s age, overall health, and medical conditions, but the definition of high blood pressure doesn’t simply change with age.
For children
Normal blood pressure does vary by age, sex, and height, so pediatric blood pressure is interpreted using specialized charts rather than a single cutoff.
Tips for accurate readings
- 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, or exercise for about 30 minutes beforehand.
- Take two readings 1–2 minutes apart and record the average.
If you tell me your age and your blood pressure reading (for example, 128/78), I can help you understand what category it falls into.
