Average splenic length?

Average splenic length?

• A. 9-11 cm
• B. 14-16 cm
• C. 11-13 cm
• D. 8-10 cm

Answer: (C)

Normal splenic length in an adult is about 11–13 cm, with 12 cm often cited as the average. In ultrasound, you measure along the spleen’s long axis from the superior to the inferior pole, typically with the patient supine or slightly decubitus to avoid distortion. Values within roughly 11–13 cm fit the standard normal range; a length of 14–16 cm would suggest splenomegaly, while 8–10 cm or 9–11 cm are at or below the lower end of normal and could indicate a smaller spleen. So 11–13 cm is the best answer because it aligns with the common normal adult splenic length.
