Quick answer
Pulse pressure is systolic minus diastolic; a normal value is 40 mmHg and a wide gap suggests stiff arteries.
PP = SBP − DBP

Frequently asked questions
What causes wide pulse pressure?
Arterial stiffening with age, aortic regurgitation or hyperthyroidism.
What does narrow mean?
It can indicate low stroke volume, as in heart failure or blood loss.
What do I need to enter into the Pulse Pressure Calculator?
Just 3 values: systolic, diastolic, heart rate. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Pulse Pressure Calculator work out the answer?
Pulse pressure is systolic minus diastolic; a normal value is 40 mmHg and a wide gap suggests stiff arteries. It applies the formula PP = SBP − DBP and shows the working so you can check each step by hand.
Is the Pulse Pressure Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
