Blood pressure can vary slightly by individual health, but here are the generally accepted normal ranges by age based on major medical guidelines.
🩺 What the Numbers Mean
-
Systolic (top number): Pressure when the heart beats
-
Diastolic (bottom number): Pressure when the heart rests
📊 Normal Blood Pressure by Age (Adults)
| Age Group | Normal Range (mmHg) |
|---|---|
| 18–39 years | ~90/60 to 120/80 |
| 40–59 years | ~90/60 to 130/85 |
| 60+ years | ~90/60 to 140/90* |
*Many experts still aim for below 130/80 if tolerated.
🟢 Standard Adult Categories (Most Guidelines)
-
Normal: Below 120 / 80
-
Elevated: 120–129 / below 80
-
High Blood Pressure (Stage 1): 130–139 / 80–89
-
High Blood Pressure (Stage 2): 140+ / 90+
-
Hypertensive Crisis: 180+ / 120+ (seek immediate care)
These categories are supported by organizations like the American Heart Association.
👶 Children & Teens
Normal values for children depend on age, height, and sex — pediatric charts are used rather than a single number.
⚠️ Important Notes
-
A single high reading doesn’t always mean hypertension.
-
Measure after 5 minutes of rest.
-
Avoid caffeine or exercise 30 minutes before checking.
-
Home monitoring can give more accurate averages.
