What is considered normal for adults?
| Blood pressure (mmHg) | Category |
|---|---|
| Less than 120/80 | Normal |
| 120–129 and less than 80 | Elevated |
| 130–139 or 80–89 | High blood pressure (Stage 1) |
| 140/90 or higher | High blood pressure (Stage 2) |
A diagnosis of high blood pressure is usually based on multiple readings taken on different days—not a single measurement.
Does age matter?
Blood pressure tends to increase with age because arteries become stiffer. However, that doesn’t mean higher numbers are considered “normal” or ideal. Older adults can still benefit from keeping blood pressure well controlled, although treatment goals may be individualized based on overall health and other medical conditions.
Children and teenagers
For children, normal blood pressure does vary by age, sex, and height, so doctors use specialized charts rather than a single cutoff.
How to measure your blood pressure accurately
- Sit quietly for 5 minutes before measuring.
- Keep your feet flat on the floor and your back supported.
- Rest your arm at heart level.
- Avoid caffeine, smoking, and exercise for 30 minutes beforehand.
- Take two readings, about one minute apart, and record both.
When to seek medical care
- If your readings are consistently 130/80 mmHg or higher, arrange an appointment with your healthcare provider.
- If your blood pressure is 180/120 mmHg or higher, especially if you have symptoms such as chest pain, severe headache, shortness of breath, weakness, or vision changes, seek emergency medical care immediately.
Bottom line
There isn’t a separate “normal blood pressure by age” chart for adults. The goal for most adults is to maintain a blood pressure in the normal range (below 120/80 mmHg), while treatment targets should be individualized by a healthcare professional based on your overall health.
