According to the U.S. Census Bureau, the county has a total area of 586 square miles (1,520 km2), of which 581 square miles (1,500 km2) is land and 5.2 square miles (13 km2) (0.9%) is water.

Macon County is primarily flat, as is most of the state and all of the surrounding counties, the result of geological activity during the Pleistocene epoch. During the Illinoian Stage of the Pleistocene, the Laurentide ice sheet covered roughly 85 percent of Illinois, including all of present-day Macon County. The subsequent thaw of the region and retreat of the ice sheet left central Illinois with the characteristic flat topography which it is known for today.

Because of its central location, Macon County is often referred to as "The Heart of Illinois."
