Small/Large Intestine Length Ratio. In humans, the small intestine is about 6 meters or 20 feet long and the large intestine is about 1.5 meters or 5 feet long. The gastrointestinal tracts of the Chimpanzee, Orangutan, and adult human and a human fetus were studied and compared by Stevens and Hume in 1995.
It is a myth that the intestines from one person can stretch around the world. The circumference of the Earth is about 24,901 miles. Since the average adult intestines stretch about 25 feet, it would take 211.2 human intestines to span one mile. This means that it would take the intestines of 5,259,091.2 average adults to stretch around the entire world.
