Floor area ratio (FAR) (also floor space ratio (FSR), floor space index (FSI), site ratio and plot ratio) is the ratio of a building's total floor area (gross floor area) to the size of the piece of land upon which it is built.The terms can also refer to limits imposed on such a ratio. As a formula:Thus, an FSI of 2.0 indicates that the total floor area of a building is two times the gross area of the plot on which it is constructed, as would be found in a multiple-story building.n India floor space index (FSI) and floor area ratio (FAR) are both used. In the United Kingdom and Hong Kong both plot ratio and site ratio are used. In Singapore the terms plot ratio add gross plot ratio (GPR) are more commonly used.
