Blood pressure is an important and vital health indicator. High blood pressure (arterial hypertension) may cause changes to blood vessels, resulting in Atherosclerosis, also known as “hardening of the arteries”. Atherosclerosis is the leading cause of stroke, heart attacks and peripheral vascular disease.
Check your BP value with our blood pressure calculator.
Use the tool provided below to find out whether your blood pressure is low, normal or high. Consult your personal doctor for more information on blood pressure and possible complications of high / low blood pressure. This tool may be used for orientation purposes only.

You can also compare your blood pressure level against a blood pressure chart.
Please input your systolic and diastolic blood pressure values into the tool provided below. For more information on blood pressure check out these useful links:
Systolic blood pressure
Diastolic blood pressure
- Before measurement it is necessary to calm down – sit down for 5 minutes.
- The measurement should always be performed before eating (not on a full stomach) and every day at about the same time. Before measurement it is also not advisable to drink coffee, alcohol or smoke cigarettes.
- Cuff must be placed correctly – if measuring on the arm cuff should be placed above the elbow (elbow and cuff should be 2 fingers apart). If wrist cuff is used it should be placed one finger above the wrist. Cuff must always be placed on the left arm as heart is on the left side of your chest. There are some rare occasions where people are born with heart on the right side of chest. In that case, cuff must be placed on the right arm.
- If you are very obese a wrist measurement is more handy.
- It is very important to know that when performing measurement of blood pressure you need to set the meter to at least 40 mmHg higher pressure than your normal upper blood pressure is. If your normal systolic blood pressure is about 150 mmHg set your meter to least 190 mmHg. In semi-automatic blood pressure meter you can do this manually by pumping the air into cuff, on automatic meter this value is set by a button.
- Take a few minutes between two consecutive measurements as blood vessels needs to expand properly again otherwise the second measurement will always be lower than the first.
- Be aware that blood pressure normally fluctuates and two consecutive measurements will not show same result. That’s normal.
- Patients with arrhythmia will usually get false results using electronic pressure gauge. The possibility of arrhythmia must be considered whenever the measurement shows “impossible” values, for example 150/135 mmHg. In that case it’s better to buy a classic mercury pressure gauges to obtain proper blood pressure value.
- Enter your daily measurements of blood pressure into a special chart (chart usually comes with a purchase of the device). This information is very useful for your doctor and yourself.
- For most reliable measurements it is recommended that you take your blood pressure meter to an authorized service center where they will re-calibrate it for you. Do this at least once per year.
If you have increased blood pressure you must act to lower it! More information on lowering blood pressure.
