How to use it
- 01Enter the systolic and diastolic values from the same blood-pressure reading.
- 02Review the resulting adult category and the short guidance note.
- 03Use repeated measurements and clinical advice rather than relying on one reading alone for medical decisions.
Result guide
- When systolic and diastolic fall into different categories, the higher category determines the result.
- This page is intended for general adult screening only.
- Urgent symptoms or crisis-range readings should be treated as medical issues, not just online-calculator results.
About this calculator
Blood-pressure classification pages are useful because people often receive numbers from a cuff or a routine checkup and want a quick sense of what those numbers mean.
This version keeps the scope narrow: one adult reading, one category, and general next-step language. It is not a diagnosis and is not intended for pregnancy-related or pediatric interpretation.
Frequently asked questions
Does one high reading confirm hypertension?
No. A single reading can be affected by stress, positioning, cuff size, and timing, so repeated measurements and clinical review still matter.
Is this for pregnant people or children?
No. This page is intended for general adult screening and does not replace specialized interpretation for pregnancy or pediatric care.
What if my reading is in crisis range?
Treat crisis-range readings seriously and seek urgent medical care, especially if symptoms are present.
