Your Small Intestine Is Incredibly Long — and Packed Like an Accordion

Most people are shocked to learn that the small intestine is about 20 feet long—roughly the length of a school bus seat!

But here’s the amazing part: it fits inside your abdomen because it’s folded tightly like an accordion.

  • The inner lining has tiny, finger-like structures called villi, which massively increase surface area.
  • If stretched out completely, your small intestine would cover an area the size of a tennis court!
  • This design allows it to absorb nutrients efficiently, making it one of the most high-performance organs in your body.
