Synopsis: Our Blood pressure chart shows if adults and children have high, low, or normal blood pressure according to their age. When blood pressure measurements are written, both numbers 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 (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.

Blood Pressure

Blood pressure is the pressure of blood pushing against the walls of your arteries. Arteries carry blood from your heart to other parts of your body. The American College of Cardiology and the American Heart Association divides blood pressure into four general categories. Ideal blood pressure is categorized as normal. Increased blood pressure may be classified as elevated, stage 1, or stage 2, depending on the specific numbers. High blood pressure (hypertension) can be dangerous if not treated. It can put you at risk for stroke, heart failure, kidney failure, and other medical problems - Sources: American College of Cardiology and American Heart Association.

Main Digest

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 that there is no flow. As the pressure is released from the bladder, you will hear the blood flowing again. That point becomes your blood pressure systolic reading. The diastolic reading is when you hear no sound again, which means the blood flow is back to normal.

Blood Pressure Charts for Adults

What is LOW Blood Pressure?
Blood pressure that is too low is known as Hypotension.
Systolic pressure (mm Hg) Diastolic pressure (mm Hg) Pressure Range
90 60 Borderline Low blood Pressure
60 40 Too Low Blood Pressure
50 33 Dangerously Low Blood Pressure

 

What is NORMAL Blood Pressure?
Systolic pressure (mm Hg) Diastolic pressure (mm Hg) Pressure Range
130 85 High Normal Blood Pressure
120 80 Normal Blood Pressure
110 75 Low Normal Blood Pressure

 

What is Classed as HIGH Blood Pressure?
If one or both numbers are usually high, you have high blood pressure (Hypertension).
Systolic pressure (mm Hg) Diastolic pressure (mm Hg) Stages of High Blood Pressure
210 120 Stage 4
180 110 Stage 3
160 100 Stage 2
140 90 Stage 1

NOTE: 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.
