Small intestine surface area

It is approximately 20-25 feet in length and is about as big around as your middle finger. The length of the small intestine can vary greatly, from as short as 3 metres (10 feet) to as long as 10.5 m (34+1⁄2 ft), also depending on the measuring technique used. The typical length in a living person is 3–5 m (10–16+1⁄2 ft). The length depends both on how tall the person is and how the length is measured. Taller people generally have a longer small intestine and measurements are generally longer after death and when the bowel is empty.
