The mean weight of the right lung of an adult male is about 16 ounces, and the left lung weighs 14 ounces, reports the U.S. National Library of Medicine. The mean weight of the right lung of an adult female is 12 ounces, with the left lung at 10.5 ounces.
The average height of the lungs are 7.8 inches for the left lung, and 8.3 inches for the right lung, notes the Human Monitoring Laboratory. The left lung is about 4 inches wide, and the right is about 4.5 inches wide. However, their total combined surface area can be as much as 1,000 square feet, or the size of half a tennis court, according to InnerBody. Human lungs also have about 1,500 miles of bronchial tubes and other airways and as much as half a billion alveoli, the tiny air sacs that exchange carbon dioxide and oxygen.
