Synopsis: Describes the significance of blood pressure readings, encompassing the ranges for normal, optimal, and concerning levels across different age groups. Blood pressure measurements are written as one above, or before, the other, with the systolic reading being the first number and the diastolic blood pressure measurement the second number, for example, 120/75 or (120 over 75). Systolic Pressure is the blood pressure reading when your heart beats. This reading is always the first or top number. Diastolic Pressure is blood pressure measurement when your heart relaxes. This is always the second or bottom number.


NOTE: High blood pressure often does not cause any signs of illness that you can see or feel. It is important to make an appointment with your doctor or another healthcare provider to check your blood pressure.

What Does Blood Pressure Refer To?

Blood pressure refers to the force exerted by circulating blood on the walls of blood vessels and constitutes one of the body's principal vital signs. The pressure of the circulating blood decreases as blood moves through your arteries, arterioles, capillaries, and veins. The term blood pressure generally refers to your arterial pressure, i.e., the pressure in the larger arteries, arteries being the blood vessels that take blood away from the heart. Blood pressure is always given as two numbers;

When the measurements are written, both are written as one above or before, the other with the systolic being the first number, for example, 120/75 (120 over 75). Blood pressure measurement is NOT the same as your heart rate (pulse) or maximum heart rate measurement. Check what your heart rate for your age should be. You can calculate your predicted maximum heart rate by using the calculation: 220 - (age) = Age Predicted Maximum Heart Rate - or see our Target Heart Rate Calculator and Chart.

Measuring Your Blood Pressure

Healthcare professionals use a stethoscope and a manual sphygmomanometer to measure your blood pressure. Typically, they take the reading above your elbow. The sphygmomanometer has a bladder, cuff, bulb, and gauge. When the bulb is pumped, it inflates the bladder inside the cuff wrapped around your arm. This inflation will stop the blood flow in your arteries.

The stethoscope is used to listen for the sound of the heartbeat, and no sound indicates no flow. As the pressure is released from the bladder, you will hear the blood flowing again. That point becomes reading your blood pressure systolic. The diastolic reading is when you hear no sound again, which means the blood flow is back to normal.

Blood Pressure Reading for Adults
Blood PressureSystolic mm HgDiastolic mm Hg
Normal Less Than 120 and Less Than 80
Blood pressure numbers of less than 120/80 are considered within the normal range. Keep up heart-healthy habits, follow a balanced diet, and exercise regularly.
Elevated 120 - 129 and Less Than 80
This level of blood pressure is when readings consistently range from 120-129 systolic and less than 80 mm Hg diastolic. Steps should be taken to control your blood pressure.
Hypertension Stage 1 130 - 139 or 80 - 89
At this stage of high blood pressure, doctors are likely to prescribe lifestyle changes. They may consider adding blood pressure medication based on your risk of atherosclerotic cardiovascular diseases, such as heart attack or stroke.
Hypertension Stage 2 140 or Over or 90 or Over
At this stage of high blood pressure, doctors are likely to prescribe a combination of blood pressure medications and lifestyle changes.
Hypertensive Crisis Over 180 and/or Over 120
This level of high blood pressure requires medical attention immediately. You may experience chest pain, shortness of breath, back pain, numbness or weakness, change in vision, or difficulty speaking.

Blood Pressure Chart By Age

Creating a comprehensive blood pressure chart by age involves several factors, including gender and health status. However, here's a general guideline for blood pressure ranges by age for adults:

Blood Pressure by Age Table
Age Group Systolic BP (mm Hg) Diastolic BP (mm Hg)
18-29 120-129 80-84
30-39 120-129 80-84
40-49 130-139 85-89
50-59 130-139 85-89
60+ 140 or higher 90 or higher

NOTE: These ranges are based on guidelines from organizations like the American Heart Association. However, individual health conditions and other factors may influence what's considered a normal range for blood pressure. A healthcare provider recommends you get your blood pressure checked at least once a year. If you have been diagnosed with high blood pressure (or other related conditions), your doctor may recommend getting it checked more often.
