It is the ratio between the plot area and the total built-up area of the building. Calculate F.A.R by just putting your plot size and the rest will be done for you as per your city.

F.A.R stands for floor area ratio which is used to determine the total built-up area allowed on a particular plot as per the local building by laws. It also helps to determine the total number of floors permissible on a plot or the total height of the building. Our F.A.R calculator will give you the max built-up area, total no of floors and the permissible building height as per your plot area entered.
