What is Floor Area Ratio?

Floor Area Ratio (FAR), also known as Floor Space Index (FSI), Floor Space Ratio (FSR), or Plot Ratio, is a planning and zoning regulation used in urban development to control the size and density of buildings relative to the size of the land on which they are situated. FAR represents the ratio of a building's total floor area to the total area of the land parcel on which it is built. It is calculated by dividing the total floor area of all floors of a building by the total area of the land parcel.
FAR regulations vary by jurisdiction and can influence the scale, design, and density of development within a given area. Higher FAR values allow for more intensive land use, permitting taller buildings or larger structures on smaller land parcels. Conversely, lower FAR values promote lower-density development, resulting in shorter buildings and more open space.
