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 measurements are written as a pair of numbers: The systolic pressure (the top number) is a measure of the pressure the blood exerts against the arterial walls when the heart contracts. The diastolic pressure (the bottom number) is the pressure between contractions.lood pressure is the pressure inside the arteries (blood vessels). It is measured in two numbers, such as 110/70 (110 over 70). Adults 18 years and older: 1  The first or top number (systolic pressure) is the highest pressure in the arteries when the heart pumps blood into them.
