Blood pressure is an important physiological parameter that indicates the force exerted by the blood against the walls of the arteries.
It is measured in millimeters of mercury (mmHg) and consists of two values – systolic pressure and diastolic pressure. Systolic pressure represents the force when the heart contracts, while diastolic pressure corresponds to the force when the heart relaxes between beats.
Normal blood pressure readings vary based on age, and understanding these variations is crucial for assessing an individual’s cardiovascular health.
Understanding Blood Pressure Readings
Before delving into the normal blood pressure readings by age, it is essential to understand the classification of blood pressure values. The following table provides the general categories of blood pressure readings:.
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | < 120 | < 80 |
| Elevated | 120-129 | < 80 |
| Hypertension Stage 1 | 130-139 | 80-89 |
| Hypertension Stage 2 | ≥ 140 | ≥ 90 |
| Hypertensive Crisis | ≥ 180 | ≥ 120 |
These guidelines provide a general overview, but it is important to consider age-specific blood pressure readings for a more accurate assessment.
Normal Blood Pressure Readings by Age
The normal blood pressure readings can vary across different age groups. Here is a breakdown of the normal blood pressure ranges by age:.

Infants (0-12 months)
The cardiovascular system of infants is still developing, so blood pressure levels are generally lower compared to older age groups. The following table shows the normal blood pressure ranges for infants:.
| Age Range | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Newborn (0-3 days) | 60-90 | 20-60 |
| 1 month | 70-100 | 35-65 |
| 3 months | 85-105 | 45-70 |
| 6 months | 90-110 | 60-75 |
| 9-12 months | 90-115 | 60-75 |
Children (1-12 years)
During childhood, blood pressure gradually increases. Here are the normal blood pressure ranges for children:.
| Age Range | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| 1-2 years | 85-105 | 55-75 |
| 3-5 years | 90-110 | 55-75 |
| 6-9 years | 95-115 | 60-80 |
| 10-12 years | 100-120 | 60-80 |
Adolescents (13-19 years)
During adolescence, blood pressure levels continue to increase before stabilizing in adulthood. Here are the normal blood pressure ranges for adolescents:.
| Age Range | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| 13-15 years | 110-120 | 70-80 |
| 16-19 years | 115-120 | 70-80 |
Adults (20 years and older)
In adulthood, blood pressure is categorized into three groups: normal, elevated, and hypertension. The following table outlines these categories for adults:.
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | < 120 | < 80 |
| Elevated | 120-129 | < 80 |
| Hypertension Stage 1 | 130-139 | 80-89 |
| Hypertension Stage 2 | 140-159 | 90-99 |
| Hypertension Stage 3 | ≥ 160 | ≥ 100 |
| Hypertensive Crisis | ≥ 180 | ≥ 120 |
Conclusion
Monitoring blood pressure is essential for maintaining cardiovascular health and preventing potential complications. Normal blood pressure readings vary by age, with lower values observed in infants and higher values in adults.
Understanding age-specific blood pressure ranges allows for more accurate assessments. Regular blood pressure check-ups, especially during routine medical examinations, can help identify any deviations from the normal range and prompt appropriate interventions.
