According to the U.S. Census Bureau, the county has a total area of 674 square miles (1,746 km²), of which 664 square miles (1,719 km²) is land and 10 square miles (26 km²) (1.51%) is water.
The county forms part of the semi-rural, sparsely-populated eastern portion of the St. Louis metropolitan area (nicknamed "Metro East") along with neighboring Madison County. Unlike the suburbs on the Missouri side of the metro area, those in Metro East are typically separated by large swaths of corn and soybean fields or otherwise undeveloped land. Thus, low-income neighborhoods in East St. Louis, Washington Park, and other cities in St. Clair County often border agricultural or vacant lands. In some places, truck stops, strip clubs, and other semi-rural businesses abut these neighborhoods as well.
