What size is your stomach?

Published in Human Anatomy 1 min read

My stomach, like most adult stomachs, has a fairly consistent size despite variations in body weight. Here's a breakdown of the dimensions:

Dimensions of an Empty Stomach

  • Length: Approximately 12 inches long.
  • Width: About 6 inches across at its widest point.

This is the size of the stomach when it's empty and not distended. It’s important to note that these are average sizes and slight variations can occur.

Stomach Capacity When Full

While the empty stomach is a specific size, it can expand to hold a significant amount of food. As an adult, my stomach can expand to hold about 1 quart of food.

Full Varies Varies 1 quart

Additional Points to Consider

  • Stomach Size vs. Weight: A person's stomach size is not directly correlated to their overall weight. Most adults have roughly the same size stomach.
  • Expansion: The stomach is designed to expand to accommodate the food we eat, but it is also capable of contracting back to its regular size.
