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.
Blood pressure readings are given in two numbers. The top number is the maximum pressure your heart exerts while beating (systolic pressure), and the bottom number is the amount of pressure in your arteries between beats (diastolic pressure). The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure.
