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 first, or top number, is your pressure when your heart beats, called the systolic pressure. The second, or bottom number, measures the force of blood in your arteries while your heart is relaxed (filling with blood between beats). This is called the diastolic pressure.ystolic pressure.
