Blood pressure is an important indicator of cardiovascular health, and knowing what your numbers mean can help you recognize when you may need medical advice.
One important thing to understand: normal blood pressure does not increase automatically with age. Although blood pressure often rises as people get older, healthy targets for most adults remain similar. Children and teenagers are assessed differently, and individual targets may vary depending on medical conditions and treatment.
Blood pressure ranges by age
These are general reference points, not separate age-based targets. Adult categories below follow the American Heart Association’s classification.

When is blood pressure an emergency?
If your reading is above 180 systolic and/or 120 diastolic, wait at least one minute and measure again. If it remains that high, seek urgent medical advice. If you also have chest pain, difficulty breathing, weakness, vision changes, or difficulty speaking, call your local emergency service immediately.

How to measure your blood pressure correctly
- Sit quietly for five minutes before measuring.
- Keep your back supported and feet flat on the floor.
- Rest your arm at heart level.
- Avoid caffeine, smoking, and exercise for 30 minutes beforehand.
- Take two readings one minute apart and record both.
