What is the normal upper limit for spleen length?

Explanation:
Understanding this question starts with how we define normal spleen size on imaging. We measure the spleen’s greatest length along its long axis. In adults, the upper limit of normal is about 13 cm. That means a spleen length below 13 cm is within normal size, and a length above 13 cm is typically considered splenomegaly. So the option stating the normal upper limit as less than 13 cm correctly reflects that threshold. Keep in mind that individual size varies with age and body habitus; in pediatric patients or smaller adults, the normal limit is smaller, while taller individuals can have longer spleens. The other numbers fall outside the standard cut-off used to flag enlargement.
