# How to Calculate Floor Area Ratio?

Floor area ratio (far) is the measurement of a building’s floor area in relation to the size of the lot/parcel that the building is located on. Far is expressed as a decimal number, and is derived by dividing the total area of the building by the total area of the parcel (building area ÷ lot area).

## How to Calculate Floor Area Ratio?

Floor area ratio (FAR) is an important concept used by urban planners and architects to measure a building’s size in relation to its plot of land. Calculating the FAR of a building is necessary for zoning and regulation purposes, as it gives a good indication of the density and intensity of use of the land. Knowing how to calculate FAR is essential for any project involving mixed-use development, as it is a key indicator used to assess the potential of a certain plot of land.

The first step in calculating FAR is to determine the area of the plot of land in question. This should include all the land within the boundaries of the plot, including any open space and landscaping. Measurements should be taken from the outer boundaries of the plot, and the area should be calculated in square feet.

Once the area of the plot has been determined, the next step is to measure the total floor area of the building. This should include all the floors, including basements, attics, and mezzanine levels. Measurements should be taken from the outside of the exterior walls and the area should be calculated in square feet.

Now that the plot area and building area have been determined, the next step is to
