What does this blood-pressure reading mean?
Enter a reading you took on your own cuff. This page reports where those two numbers fall in the 2025 AHA/ACC Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults, and works out pulse pressure and estimated mean arterial pressure.
Your reading stays in this browser. The arithmetic runs on your device. Nothing is sent to us, because there is nowhere to send it to — this site has no server that receives data. How that is enforced.
The published categories
This is the table the calculator reads. Note that the two lower bands use and while the two stages use or, so a reading can sit in a higher band on one number alone — 119/85 falls in the stage 1 row on its diastolic number.
| Category | Systolic (mm Hg) | And / or | Diastolic (mm Hg) |
|---|---|---|---|
| Normal | Below 120 | and | Below 80 |
| Elevated | 120–129 | and | Below 80 |
| Stage 1 hypertension | 130–139 | or | 80–89 |
| Stage 2 hypertension | 140 or higher | or | 90 or higher |
What this is not
- Not a measurement. This page has no transducer and derives nothing from a signal — it accepts a number you measured on your own device.
- Not a diagnosis, a risk score, or a decision aid.
- Not personalised. There is no age, sex, weight, medication or condition input here, and there will not be one.
- Not a substitute for the person who looks after your health. What this page actually does.
