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.
The two numbers that measure your blood pressure are written like a fraction: one number on top and one on the bottom. The top number in a blood pressure reading refers to the systolic pressure. It measures the pressure inside your blood vessels at the moment your heart beats. The bottom number represents your diastolic pressure. It measures the pressure in your blood vessels when your heart is resting between heartbeats.
