What is the normal size of the spleen?

Normal spleen size varies among individuals, but can generally be summarized as follows: 1. Length: The spleen is typically 10–12 cm in length, representing its maximum dimension along the long axis. 2. Width: The width of the spleen is approximately 6–8 cm, depending on its transverse dimension within the body. 3. Thickness: There are gender differences in spleen thickness. In males, it usually does not exceed 4 cm, while in females it should be less than 3.7 cm. 4. Weight: The spleen weighs approximately 110–200 g, comparable in size to an adult's palm. Spleen size may be influenced by various factors, including age, sex, individual variation, and physiological status. In certain conditions, such as disease states, the spleen may become enlarged or reduced in size.
