Blood Pressure Category
Enter your systolic and diastolic blood pressure to classify it from Normal to Grade 3 hypertension using the JSH 2019 categories. Also calculates pulse pressure and mean arterial pressure.
Input
Enter the blood pressure measured at a clinic. Home measurements use different thresholds.

Adult blood pressure categories (clinic, JSH 2019)
| Category | Systolic (mmHg) | and / or | Diastolic (mmHg) |
|---|---|---|---|
| Normal | Under 120 | and | Under 80 |
| High-normal | 120–129 | and | Under 80 |
| Elevated (you) | 130–139 | and | 80–89 |
| Grade 1 hypertension | 140–159 | or | 90–99 |
| Grade 2 hypertension | 160–179 | or | 100–109 |
| Grade 3 hypertension | 180 and above | or | 110 and above |
If the systolic and diastolic values fall in different categories, the higher (more severe) category applies.
How it works
- Enter your systolic (upper) and diastolic (lower) blood pressure to classify it using the clinic blood pressure categories of the Japanese Society of Hypertension's 2019 guidelines (JSH 2019).
- The categories are: normal (under 120/80), high-normal (120–129 and under 80), elevated (130–139 or 80–89), grade 1 hypertension (140–159 or 90–99), grade 2 hypertension (160–179 or 100–109), and grade 3 hypertension (180 and above or 110 and above).
- When the systolic and diastolic values fall in different categories, the higher one applies.
- It also calculates and shows pulse pressure (systolic − diastolic) and mean arterial pressure (diastolic + pulse pressure ÷ 3).
- Blood pressure varies with your condition and the time of day. Home measurements use a threshold 5 mmHg lower than clinic measurements, so the basis for evaluation differs.
- This tool offers a general guide based on standard categories and is not a diagnosis or medical advice. Always consult a doctor for health decisions.
