Katy Mills is a one story facility that sits on 1.3 square miles (3.4 km2) of land, located just off Interstate 10 exit 741. The mall is built with a "racetrack" design and one complete pass around the mall on Katy Mills Cir. road is approximately 1 mile (1.6 km).
Originally, the mall featured a Jillian's restaurant and entertainment center. It closed in 2004 and became Steve & Barry's, which closed in 2008. It also featured a Circuit City prototype called "The City", which opened and closed in 2008.
The entire shopping mall is located within Fort Bend County, Texas, although a small portion of the parking lot is located in neighboring Harris County.
