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.
First, a breakdown of what your reading entails. The top number is your systolic pressure, or the pressure that arises from your heart pumping blood into your bloodstream, says Kevin Campbell, M.D., an assistant professor of cardiology at the University of North Carolina. The bottom number is your diastolic pressure. Thatâs the relaxation phase of the pumping process, when your heartâs ventricle is filling and getting ready to take in the next pump. Both numbers are important to your heart health. A normal blood pressure reading will clock in below 120/80. To put it another way, your systolic will be below 120 and your diastolic will be below 80. (Low blood pressure, called hypotension, occurs when your reading measures lower than 90/60.
