The CHARA Array is a long baseline optical/infrared interferometer, uniquely suited to measure the angular diameters of stars. In this presentation, we summarize the current results of a survey measuring diameters of nearby, main-sequence stars. This project consists of the most accurate and largest homogeneous data set that provides direct measurements of the stellar linear radius and effective temperature for stars of this type. We highlight the challenges these data bring to current stellar atmospheric and evolutionary models, as well as newly defined empirically based relations to the stellar effective temperature and radius.
