how long is your small intestine

Your small intestine is usually around 20–22 feet (about 6–7 meters) long in an adult.

Quick Scoop

• In most adults, the small intestine is about 22 feet (≈7 m) long when stretched out.

• Medical sources often give a range of roughly 10–16 feet measured inside the body, because it’s folded and not fully stretched.

• It’s the longest part of your digestive tract, even though it’s called “small” because its diameter is narrower than the large intestine.

• Exact length varies from person to person, depending on height, body size, and how it’s measured (during life vs. after death, stretched vs. relaxed).

Mini breakdown of its parts

• Duodenum: about 8–10 inches long.

• Jejunum: around 8 feet long.

• Ileum: close to 10 feet long.

Put together, that gives the “around 20+ feet” total you often hear.

In everyday terms: if you could gently stretch your small intestine out in a straight line, it would be about as long as a one‑story house or a big yellow school bus.

TL;DR: Your small intestine is typically about 20–22 feet long, with normal variation above and below that range.
