Important: A single home reading is not a diagnosis. If your reading
is very high or you have symptoms such as chest pain, shortness of breath, weakness, or severe headache,
seek urgent medical help.
How it works
Understand your blood pressure category
This Blood Pressure Category Calculator uses systolic and diastolic values together to place a reading into a common category.
It is for awareness and education only. Diagnosis and treatment decisions should be made with a qualified healthcare professional.
Fast category check
Enter both numbers and the calculator displays the category with a short explanation.
Guideline style ranges
The calculator uses common ranges such as normal, elevated, stage 1, stage 2, and crisis level.
Health awareness
Use the result as a prompt to track readings and talk with a clinician when readings are repeatedly high.
Frequently asked questions
A normal category is usually below 120 systolic and below 80 diastolic. Home
technique, cuff size, posture, and timing can affect readings.
Elevated blood pressure generally means systolic pressure is 120–129 while diastolic
pressure is below 80.
Stage 1 hypertension is commonly categorized when systolic is 130–139 or diastolic is
80–89.
Very high readings above 180 systolic or above 120 diastolic may be considered crisis
range. If symptoms are present, seek emergency care immediately.
No. This calculator does not diagnose hypertension and does not recommend treatment.
It is a simple educational category checker.
