What This Calculator Does
The Blood Pressure Category Calculator classifies your systolic and diastolic readings according to the American College of Cardiology and American Heart Association 2017 guidelines. It shows your combined reading and pulse pressure.
How It Works
Enter your systolic (top number) and diastolic (bottom number) in mmHg. The calculator shows your combined reading and pulse pressure. Normal is below 120/80, Elevated is 120-129 below 80, Stage 1 is 130-139 or 80-89, Stage 2 is 140+ or 90+, Crisis is 180+ or 120+.
Example
A reading of 138/88 mmHg: pulse pressure is 50 mmHg and falls into Stage 1 Hypertension.
Formula
Pulse Pressure = Systolic - DiastolicReading the Results
Pulse Pressure
The gap between systolic and diastolic. Normal is 30-40 mmHg. Higher values may indicate arterial stiffness.
Frequently Asked Questions
What is considered normal blood pressure?
Normal blood pressure is below 120/80 mmHg. Elevated blood pressure is 120-129 systolic with diastolic below 80.
When should I see a doctor?
If your reading consistently falls in Stage 1 or higher, consult a healthcare professional. Hypertensive Crisis (180+/120+) requires immediate medical attention.
How often should I check?
If you have elevated or high readings, check daily at the same time. For normal readings, periodic checks every few months are sufficient.
