The liver’s main mass sits under the right lower ribs and occupies the right hypochondrium, but its bulk extends across into the epigastric region, making the central upper part of the abdomen—the epigastric region—the area where it occupies the greatest portion. The right lobe dominates under the right costal margin, while the left lobe reaches toward the left hypochondrium; despite these extensions, the liver as a whole is largest in the epigastric region, which is why that region is described as containing the greater part of the liver. This region spans the central upper abdomen, situated above the umbilicus and bounded by the costal margins, aligning with the liver’s diaphragmatic contact and its substantial vertical extent.
