Blood Pressure Range Calculator

This calculator helps you assess your blood pressure levels by entering systolic and diastolic values. It determines whether your blood pressure is normal, elevated, or within hypertensive stages, offering a quick and easy way to monitor cardiovascular health.

Blood Pressure Classification Based on Systolic and Diastolic Values

Formula
$$\text{Blood Pressure Category} = \begin{cases} \text{Normal} & \text{if } \text{SBP} < 120 \text{ and } \text{DBP} < 80 \\ \text{Elevated} & \text{if } 120 \leq \text{SBP} < 130 \text{ and } \text{DBP} < 80 \\ \text{Stage 1 Hypertension} & \text{if } 130 \leq \text{SBP} < 140 \text{ or } 80 \leq \text{DBP} < 90 \\ \text{Stage 2 Hypertension} & \text{if } \text{SBP} \geq 140 \text{ or } \text{DBP} \geq 90 \\ \text{Hypertensive Crisis} & \text{if } \text{SBP} \geq 180 \text{ or } \text{DBP} \geq 120 \\ \end{cases}$$
Where:

  • $$SBP$$ = Systolic Blood Pressure
  • $$DBP$$ = Diastolic Blood Pressure


Blood pressure is a vital indicator of heart health, measuring the force of blood against artery walls. Systolic pressure reflects the force during heartbeats, while diastolic shows the pressure when the heart is at rest. This tool helps users classify their blood pressure according to established medical guidelines. Regular tracking can aid in early detection of hypertension, supporting preventive care and lifestyle adjustments.
