Blood Pressure Chart By Age

A normal blood pressure is important to everyone. Many people have a higher or lower blood pressure, an abnormal blood pressure not only causes discomfort, but can be a risk factor to many severe diseases, including stroke and kidney failure. 

Your total blood pressure reading is determined by measuring your systolic and diastolic blood pressures. Systolic BP, the top number, measures the force your heart exerts on the walls of your arteries each time it beats. Diastolic BP, the bottom number, measures the force your heart exerts on the walls of your arteries in between beats. A blood pressure reading is presented as systolic/diastolic, as in 120/80, 120 represents the systolic reading, while 80 represents the diastolic reading. The measurement unit for blood pressure is mm Hg. Below is a blood pressure chart by age.

Blood Pressure Chart: Systolic BP and Diastolic BP

This blood pressure chart by age can offer you a referrence when you need to find out what your own blood pressure means. The BP numbers shown in the chart represent “typical” systolic-diastolic pairs. Even if the normal blood pressure for men is 120/80 mm Hg, it can vary slightly according to age. Since our body changes all the time, it is normal for our BP to change, as well.

New guidelines

In 2013, there was a new guideline which said people older than 60 should aim for 150/90 mm Hg. However, it was resisted by American Heart Association and a number of cardiologists.

The latest(2017) guideline from American Heart Association(AHA) and American College of Cardiology(ACC) is as below.

Blood pressure guidelines

  • Normal: Less than 120/80 mm Hg;
  • Elevated: Systolic between 120-129 and diastolic less than 80;
  • Stage 1: Systolic between 130-139 or diastolic between 80-89;
  • Stage 2: Systolic at least 140 or diastolic at least 90 mm Hg;
  • Hypertensive crisis: Systolic over 180 and/or diastolic over 120. A hypertensive crisis is a medical emergency.

A person’s blood pressure changes in day and night. Generally, the blood pressure is the lowest during 3am to 4am, then it goes up slightly until it reaches a peak sometime between 8am to 10am. It then goes down, and then goes up again to reach the second peak sometime between 3pm to 5pm. The variance can be 30-40 mm Hg within 24 hours for each person. That’s why doctors would recommend to measure your BP three times a day.
