BP category with chart.. Blood Pressure Classifier is a free online tool from the ToolsRift Finance & Health Calculators collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter your systolic and diastolic numbers. The calculator places the reading into its blood pressure category and shows a reference chart. Not medical advice.
Readings use systolic over diastolic. Common categories are normal, elevated, and stage 1 and stage 2 hypertension, with very high readings flagged as a crisis.
Systolic is the top number, the pressure when the heart beats, and diastolic is the bottom number, the pressure between beats when the heart rests.
No. This tool only classifies a single reading against standard ranges. Diagnosing high blood pressure needs repeated measurements and a doctor's assessment.
