How big is an appendix?

Published in Human Anatomy 1 min read

The appendix is typically 8 to 10 cm (3 to 4 inches) long and less than 1.3 cm (0.5 inch) wide.

Here's a more detailed breakdown of appendix size:

  • Length: The appendix usually measures between 8 and 10 centimeters (3 to 4 inches) in length.

  • Width: The diameter of the appendix is typically less than 1.3 centimeters (0.5 inch).

The cavity inside the appendix narrows significantly where it connects to the cecum (the beginning of the large intestine), while it is wider at the closed end.
