What Is the Normal Blood Pressure for Each Age?
There isn’t one specific “normal” blood-pressure number for every age. For most adults, the same general blood-pressure categories are used regardless of age. Blood pressure is written as systolic/diastolic (mmHg).
General adult blood-pressure ranges
| Category | Systolic | Diastolic |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| High blood pressure — Stage 1 | 130–139 | 80–89 |
| High blood pressure — Stage 2 | ≥140 | ≥90 |
| Severely high | ≥180 | and/or ≥120 |
A single reading doesn’t necessarily mean you have hypertension. Blood pressure can vary with stress, exercise, caffeine, illness, and the time of day. Repeated measurements taken correctly provide a much better picture.
What about older adults?
It’s a common misconception that blood pressure is supposed to become “normal” at 150/90 or 160/100 simply because someone is older. Older adults can have higher readings, particularly systolic pressure, but consistently elevated blood pressure still deserves medical assessment.
Children are different
For children and teenagers, healthy blood pressure is determined using age, sex, and height, rather than the adult cutoffs above.
Important: A reading of 180/120 mmHg or higher requires immediate attention, particularly if accompanied by chest pain, shortness of breath, severe headache, weakness/numbness, confusion, or vision changes.
