Geometry is a base tool for establishing unity in Iranian architecture and is always considered by architects due to the discipline and rule that gives architecture to architecture. The architecture of the house in terms of its specific functional role, sought to adapt the geometrical principles to the best possible shape and achieve the proper understanding of the proportions and proportions of a harmonious geometry. In shaping the architecture of the Iranian house, the geometrical and functional role of the courtyard is important. This study is conducted through field study of 20 historical houses in Kashan to discover how geometry is used in the architectural design of Kashan historical houses. In this regard, the proportions of the arena and the court in these cells have been compared. The result shows that the yard follows the golden ratio as the house design basis. The 1.414 and 1.618 ratios have the highest frequency in the study samples. In addition, in terms of the level of occupation, the courtyard has occupied 20 to 40 percent of the building.
