What Is Normal Blood Pressure Range? Blood Pressure Chart

What Is Blood Pressure (BP)?

Blood pressure, abbreviated BP, is the pressure of the blood against the arterial walls.

Blood pressure results from the force of the heart that pumps the blood into the arteries, and the force of the arteries as they resist the blood flow.

Why Are Two Values in the Blood Pressure Reading?

Blood pressure is expressed with two values, separated by a slash and with a unit (mm Hg), for example 125/85 mm Hg; pronounced “125 over 85 millimeters of mercury” (according to height of a column in a blood pressure monitor).

  • The first (higher) value (125) represents blood pressure during the heart contraction (systole in Greek) and is called systolic blood pressure
  • The second (lower) value (85) represents blood pressure during the heart relaxation (diastole in Greek) and is called diastolic blood pressure

What is Normal Blood Pressure Range?

For an adult (18 years or older), any blood pressure between 120/80 and 90/60, measured in the sitting position on the upper arm, is considered as normal.

It was found out that people with blood pressure within this range are at least risk to suffer from heart attack, stroke or other circulatory disorders (1), so it is often called optimal, ideal or healthy blood pressure range.

Standing up for a while, exercising, stress and even appointment with a doctor can increase blood pressure for more than 10 mm Hg within few minutes, so an average value from several blood pressure measurements rather than one single measurement should be considered as actual blood pressure.

Blood pressure tends to increase with age, so many doctors consider readings as high as 150/85 in old people as normal. However, many health institutions claim that blood pressure above 120/80 should be always considered as increased risk to develop a circulation-related disorder (1).

Blood Pressure Chart for Adults

  • First value 91-119 AND second value 61-79 are considered as normal BP. Examples: 115/75 , 110/65.
  • First value 120-139 ORsecond value 80-90 are considered as pre-high blood pressure or pre-hypertension. Examples: 135/85 , 115/85. Individuals in this group are at increased risk to develop high BP later in life.
  • First value 140 or above ORsecond value above 90 are considered as high BP or hypertension. Examples: 150/85 , 135/95. A person with high blood pressure often does not have any symptoms.
  • First value 90 or less ORsecond value 60 or less are considered as low BP or hypotension. Examples: 95/55 , 85/65.

    what does 135/60 mean

    • Jan Modric

      135 is the upper blood pressure detected when the heart pushes the blood into the arteries
      60 is the lower blood pressure detected when the heart is filled with the blood

    Is 125 over 95 bad when standing up

    • Hi Lee. Once the diastolic (the second reading) passes 90 it is not a good sign even if the systolic (first reading is under 140). It doesn’t matter when you are standing up or not. The diastolic must stay below 90. You need to see your doctor because you may need to start medication.

    Mine has been consistently low with the lower number even at 49 (usually 75-90, / 49-60) I feel super dizzy when I move, that’s why I started checking it. I don’t want to drop dead without one more trip somewhere?? *what are my chances of just dropping dead from it?

    • Hi Pam. Hypotension (low blood pressure) can be dangerous especially if it leads to blackouts. As you can imagine, the danger lies in the situation – a blackout while driving or when walking down stairs can cause serious injury and even lead to death. Also if your low blood pressure is related to problems with your heart rate or cardiac output then this can lead to complications like clot formation. It depends on the cause of your hypotension but it should be ignored with the readings you report. Your doctor will advise you further.

    I just went to the doctor’s today and my blood pressure was 125/72, is this normal?

    • Hi Stacy. You may also want to refer to this article https://www.healthhype.com/signs-of-high-blood-pressure-and-stages-of-hypertension.html where it states that a systolic pressure of over 120 is prehypertension. So your 125 reading is definitely a cause fo concern in that it cannot be considered normal as yet but at the same time it is not hypertension (high blood pressure). However, prehypertension precedes hypertension. So if three readings show this abnormality, you should take it seriously and start making lifestyle changes to prevent hypertension.

        I just took my blood pressure recently, it was 110/70, my blood pressure tends to change alot, i was probably under stress when it was 125/72.

  • Regina Marie

    I. Always have a normal blood pressure. Today it was reading 119/120. I freaked out. The nurse rechecked it and it was 119/60. Did it an hr later and it said 120/63

    I have been sick and stressed.

    • Hi Regina. It is quite likely that there was an error with the first reading but fluctuations in blood pressure can occur. You must understand that the first number (systolic) is the pressure when your heart contracts and the second number (diastolic) is where you heart relaxes. The systolic is usually higher than the diastolic. So keep monitoring it but this was likely an error. If you do notice an elevation then speak to your doctor.

  • Heather

    I am 17, 155 pounds, and I always have a blood pressure of 85/55 to 90/60. Is this alright?

    • Hi Heather. It is low and this is known as hypotension. While the focus is often on the dangers of high blood pressure (hypertension), low pressure can also be dangerous. We cannot say for sure what may be causing your low blood pressure, but in conditions where the heart has some problem and cannot pump with force then hypotension may be the result. Speak to your doctor as soon as possible.

  • mudgenta

    this am my bp is 79/52, with pulse rate of 91. should I be concerned?

    • Hi Mudgenta. Yes your blood pressure is very low and needs to be checked by a medical doctor. If this low blood pressure is persisting then a host of tests will need to be done to identify the exact cause. Only then can the appropriate treatment be prescribed. Low blood pressure like this can lead to dizzy spells and even blackouts which can be dangerous. Speak to your doctor as soon as possible.
