About this tool
Enter systolic and diastolic numbers and the tool sorts the reading into the usual categories: normal, elevated, stage 1, stage 2, or hypertensive crisis. Readings in the crisis range, or any reading with chest pain, breathlessness, or weakness, need urgent care. This tool is not medical advice — check with a clinician about your own readings.
Frequently asked questions
Which number matters more?
Both matter. The category uses whichever number lands in the higher band.
When should I seek urgent care?
For readings above 180/120, or any reading with chest pain, breathlessness, numbness, or weakness.
