Is my blood pressure normal? Check a reading
Enter the top (systolic) and bottom (diastolic) numbers of a reading. The checker shows which category it falls in under the International Society of Hypertension 2020 guideline. One reading is not a diagnosis: blood pressure is judged on several readings taken on different days.

When it is urgent
A reading of 180/110 or higher needs medical attention the same day. Go to an emergency department now if a high reading comes with chest pain, breathlessness, a severe headache, confusion, weakness on one side, blurred vision or trouble speaking. In India, call 112.
Measuring it right
- Sit quietly for five minutes, back supported, feet flat, arm resting at heart level.
- No caffeine, smoking or exercise in the 30 minutes before.
- Take two readings a minute apart and use the average.
- Home readings run lower than clinic ones: 135/85 at home is roughly equivalent to 140/90 in a clinic.
