Blood Pressure Calculator

Q: What is normal blood pressure?

Normal BP is below 120/80 mmHg. The first number (systolic) is pressure during heartbeats, the second (diastolic) is pressure between beats. Optimal is around 110/70 for most adults.

Q: Should I worry about one high reading?

Single readings can be elevated due to stress, caffeine, or white-coat syndrome. Hypertension is diagnosed based on multiple elevated readings taken on different days. Monitor at home and consult a doctor if consistently above 130/80.

Check your blood pressure category — normal, elevated, Stage 1, or Stage 2 hypertension. Understand systolic and diastolic readings.
