What is the normal size of the liver in adults?

Normal adult liver length is up to about 15.5 cm when measured along the right lobe (imaging-based span). This upper limit accounts for natural variation with body size, so anything under 15.5 cm falls within the normal range. Values like 18 cm or 22 cm exceed normal and suggest hepatomegaly, while 13 cm is within normal but doesn’t specify the common upper limit.
