What is the normal blood pressure range?

• A. 100/60 - 130/80
• B. 120/80 - 140/90
• C. 90/60 - 120/80
• D. 110/70 - 150/90

Answer: (A)

Normal blood pressure reflects the balance where the heart’s pumping force (systolic) and the resting pressure between beats (diastolic) stay within a healthy range so tissues receive enough blood without placing excessive strain on vessels. A practical normal range for many adults is about 100/60 up to 130/80. This covers typical systolic values from 100 to 130 and diastolic values from 60 to 80, keeping pressures well below thresholds that suggest elevated blood pressure.

Ranging up to 140/90 or higher would begin to cross into elevated or hypertensive territory, so those values aren’t considered normal. A range ending at 120/80 is a common description of normal, but the broader window up to 130/80 is often used in clinical teaching to account for natural day-to-day variation while still keeping pressures within a safe range.
