Blood Pressure Categories (Adults)
According to the American Heart Association (AHA) and other major health organizations: Category Systolic (top number) Diastolic (bottom number)
Normal < 120 mmHg and < 80 mmHg
High 120–129 mmHg and < 80 mmHg Stage 1 Hypertension 130–139 mmHg or 80–89 mmHg Stage 2 Hypertension ≥ 140 mmHg or ≥ 90 mmHg Hypertensive Crisis > 180 mmHg and/or > 120 mmHg
Note: *Hypertension is now diagnosed at 130/80 mmHg or higher*, a change from previous guidelines. 👶Blood Pressure in Children and Adolescents
In younger individuals, blood pressure is assessed using percentile curves based on age, height, and sex. Here are some approximate averages:
Age Group Mean Systolic Mean Diastolic
1 to 3 years 80–110 mmHg 50–70 mmHg
4 to 6 years 85–115 mmHg 55–75 mmHg
7 to 10 years 90–120 mmHg 60–80 mmHg
11 to 13 years 95–125 mmHg 60–80 mmHg
14–18 years 100–135 mmHg 65–85 mmHg
In a child, a value is considered high if it is at or above the 95th percentile for their age, height, and sex.
