A ranch style home (aka rancher) is also a single story home, but has a larger, rectangular footprint (compared to a bungalow).  The ranch home is a derivative of the wide Spanish hacienda.  Ranchers grew in popularity in the 1950’s as huge tracts of land were turned into suburbs with larger plots than the typical urban plots.

(Below is a rancher located in the neighborhood of Mt. Airy in Philadelphia. This is where Jeff Snader was born and raised.)
