How Long Are the Small and Large Intestines?

The lengths of the intestines can vary from person to person, but on average:

  • Small Intestine: About 20 feet (6 meters) long.
  • Large Intestine: Approximately 5 feet ( 1.5 meters) long.

The small intestine is much longer than the large intestine, and both are important for digestion and absorbing nutrients.
