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.
What Does the Diastolic Blood Pressure Number Mean? The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen. A normal diastolic blood pressure is lower than 80. But even if your diastolic number is lower than 80, you can have elevated blood pressure if the systolic reading is 120-129. 80-89 is stage 1 hypertension. 90 or more is stage 2 hypertension. 120 or more is a hypertensive crisis.
