The normal blood pressure range of persons aged 20 – 40 years is 120mm Hg systolic pressure and 80mm Hg diastolic pressure.= 120/80mmHg. By using the term "normal", we really mean the ideal figure. Anyone registering above this range is classed as being pre-hypertensive, and if not addressed can develop into high blood pressure. See the charts below for refined averages.
The Systolic pressure is when the heart`s ventricles contract and push the blood through the veins. It is called the systole, the pressure during heartbeat action. The Diastolic pressure is the lower pressure that results when air is released out of the cuff and no more sound is heard. This is called the diastole; the artery resting pressure.
Taking Blood Pressure
To learn how to use an arm cuff, monitor, stethoscope and graph, see my BP chart page. But if you prefer, you can use an easier method, the Digital BP Monitor instead, because the stethoscope quite difficult to use and understand, plus it can cause a lot of fun and laughter, not the right condition for measuring blood pressure.
The following chart is an interesting evaluation of individual age groups that was used a couple of decades ago.
The normal blood pressure range can vary depending on what age you are according to this older chart. This chart is not recognized now by conventional health institutions but some alternative practitioners accept that blood pressure levels considered normal vary from person to person.
For example, it increases with age when the elasticity of arteries is reduced.

Consult the chart above for the minimum, maximum, and average blood pressure ranges of various age groups.
It used to be the practice of adding 100 to one`s age to get a rough guide of the systolic pressure. If your age was 50 then your normal blood pressure reading would have been expected to be around 150. Then after taking your blood pressure, you would check the reading and compare it with that figure. Doing this was how you determined if you were over the norm or under. Since then that practice has been forfeited, and the ideal number of 120/80 is the gauge.
Reading Blood Pressure
Because blood pressure fluctuates all through the day, taking regular blood pressure readings at the same time each day will give a more accurate reading.
Preferable times to do this are as soon as you wake up before you have your first cup of tea in the morning and get dressed, and as soon as you finish work.
You may very well find that your readings will be lower when you monitor your own blood pressure. But be sure to be honest with yourself. It`s your health that matters.For US Blood Pressure Monitors and Reviews click here...
Some facts to take into consideration are :
When starting out on a course of supplements and lifestyle changes to reverse high blood pressure, it is good to regularly check your blood pressure to be encouraged to continue. You should see a significant drop within a few weeks toward the normal blood pressure range if you are consistent with your new routine.
A Little Bit of History
The abbreviations mmHg represent millimeters of mercury. The method of measuring blood pressure using a balloon connected to a mercury column or to an aneroid manometer was developed in 1876 by the Austrian physicist, Von Basch. The balloon was placed over the wrist artery and pressure applied until no pulse was felt. It was at this point the reading was taken which gave the systolic pressure.
