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.

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.
