For a normal reading, your blood pressure needs to show a top number thatâs between 90 and 120, and a bottom number thatâs between 60 and 80. When both your systolic and diastolic numbers are in these ranges, youâre considered by the American Heart Association (AHA) to be within the normal range for blood pressure.
For example, 110 over 70 (written as 110/70). 1  The top number is the systolic blood pressure reading. It represents the maximum pressure exerted when the heart contracts. 2  The bottom number is the diastolic blood pressure reading. It represents the minimum pressure in the arteries when the heart is at rest.
