Blood Pressure Range

High blood pressure is also known as hypertension. It is measured in mm Hg (millimetres of mercury).

Blood pressure is always given as two numbers- systolic pressure (when the heart beats) and diastolic pressure (when the heart relaxes). When the measurements are written down, both are written one above or before the other with the systolic being the first number. It is measured using an instrument called the spygnomanometer. It can also be measured digitally.

It is very difficult to correctly define normal blood pressure as the blood pressure range can vary widely. A single blood pressure monitor reading is not reliable. Blood pressure monitor readings must be taken at different times of the day to determine average blood pressure over a period.

High Blood Pressure Range
Systolic (mm Hg) Diastolic (mm Hg) Stages of High Blood Pressure
 210  120  Stage 4
 180  110  Stage 3
 160  100  Stage 2
 140  90  Stage 1

Normal Blood Pressure Range
Systolic (mm Hg) Diastolic (mm Hg) Pressure Range
 130  85  High Normal Blood  Pressure
 120  80  Normal Blood Pressure
 110  75  Low Normal Blood  Pressure

Low Blood Pressure Range
Systolic (mm Hg) Diastolic (mm Hg) Pressure Range
 90  60  Borderline Low blood  Pressure
 60  40  Too Low Blood Pressure
 50  33  Dangerously Low Blood  Pressure

  • When systolic and diastolic pressure falls into different categories, the higher category should be used to classify the blood pressure level example 160/80 mm Hg would be considered as Stage 2 High Blood Pressure.

  • A blood pressure of 130/80 mmHg would be considered as high blood pressure for people with diabetes or chronic kidney disease.

Thank you for this very simple way of giving information about your topic. A layman like me can easily understand it.I am on maintenance dose for high blood pressure; so, I am very much concerned.
