Blood pressure does not have one exact “normal” number for each age, because healthy levels depend on factors like overall health, medications, activity, and medical conditions. However, these are common reference ranges for resting blood pressure in adults:
| Age group | Typical healthy blood pressure range |
|---|---|
| Children (varies by height and sex) | About 90–120 / 60–80 mmHg (ranges vary widely) |
| Teens (13–17 years) | Around 100–120 / 65–80 mmHg |
| Adults (18–39 years) | About 90–120 / 60–80 mmHg |
| Adults (40–59 years) | About 100–130 / 60–80 mmHg |
| Adults 60+ years | Often around 110–130 / 60–80 mmHg (individual targets may differ) |
Blood pressure categories (adults)
- Normal: Below 120/80 mmHg
- Elevated: 120–129 systolic and below 80 diastolic
- High blood pressure (Stage 1): 130–139 or 80–89
- High blood pressure (Stage 2): 140+ or 90+
- Very low blood pressure: Often considered below about 90/60, especially if causing symptoms
How to read the numbers
- Top number (systolic): Pressure when your heart pumps blood.
- Bottom number (diastolic): Pressure when your heart relaxes between beats.
A single reading can be misleading. Blood pressure is usually judged by multiple readings taken on different days.
If you tell me the person’s age and their blood pressure reading (for example, “45 years old, 145/90”), I can help interpret whether it is in a typical range.
