Normal Blood Pressure Values by Age Group

Blood pressure reference values vary throughout the day and under different circumstances, fluctuating significantly. Moreover, these values are not static over a person’s lifetime; generally, blood pressure gradually increases with age. So, what are the normal blood pressure ranges for different age groups?

Normal Blood Pressure Ranges by Age Group

Blood pressure consists of two components: systolic pressure (the “upper” number) and diastolic pressure (the “lower” number). Both values change progressively with age. In adults, normal systolic pressure ranges from 90 to 140 mmHg, while normal diastolic pressure falls between 60 and 90 mmHg. In newborns, blood pressure is relatively low—approximately 70 mmHg systolic and 34 mmHg diastolic. Importantly, adult blood pressure standards must not be applied when assessing children’s blood pressure. During the first 1–6 months of life, blood pressure rises somewhat: systolic pressure exceeds 70 mmHg, and diastolic pressure typically ranges from 30 to 45 mmHg. Between ages 7 and 12 years, systolic pressure normally lies between 90 and 110 mmHg, and diastolic pressure between 60 and 90 mmHg.

Hypertension is defined as systolic pressure ≥140 mmHg and/or diastolic pressure ≥90 mmHg. This condition is termed “hypertension.” Isolated systolic hypertension refers specifically to cases where only systolic pressure reaches or exceeds 140 mmHg, while diastolic pressure remains within the normal range.

When only diastolic pressure reaches or exceeds 90 mmHg (with systolic pressure remaining normal), the condition is termed “isolated diastolic hypertension.” Generally, clinical manifestations and disease severity vary depending on the type of hypertension. However, blood pressure tends to rise progressively with age, with systolic pressure increasing more markedly than diastolic pressure. We hope this article has been helpful to you.
