The length of the small intestine in adults typically ranges from about 3 meters to 7.6 meters, with the average length commonly reported around 6 to 7 meters. The length can vary depending on factors such as measuring technique and the individual's height, with taller people generally having longer small intestines. Some sources mention the small intestine can be as short as 3 meters or as long as approximately 10.5 meters in certain measurements, but the common living length is closer to 3-7.6 meters (10-25 feet).
Summary of Length:
- Typical living adult small intestine: 3–7.6 meters (10–25 feet)
- Average reported length: about 6 meters
- Variations depend on height and measurement method
The small intestine is a long, narrow tube responsible for the majority of nutrient absorption in the digestive system. Despite its name, it is called "small" because of its diameter, which is about 2.5 to 3 cm, not its length.
