Floor area ratio (FAR)

The floor area ratio (FAR), also called floor space ratio (FSR), floor space index (FSI) or plot ratio, is calculated from the ratio between the living area and the area of the plot. It specifies the percentage of the plot area that may be used. If the maximum floor area ratio is 25%, for instance, a maximum floor area of 200 m2 is admitted on a plot of 800 m2.
