Calculate Floor Area Ratio (FAR) in Delhi

Calculate Latest FAR in Delhi


Calculating Floor Area Ratio - FAR in Delhi (As per local Building By Laws)

Step 1:

Check the Floor area ratio (FAR) for your plot in Delhi from the table below. If you have the plot size in sq. yards then make sure to convert it to sq. m by multiplying it by 0.836. The table shown below is only applicable for plots in Delhi.

Area of Delhi
Plot (sq. meter)
Max. Ground
Coverage %
FAR No. of Dwelling
Below 32 90* 350 3
Above 32 to 50 90* 350 3
Above 50 to 100 90* 350 4
Above 100 to 250 75** 300** 4
Above 250 to 750 75 225 5
Above 750 to 1000 50 200 7
Above 1000 to 1500 50 200 7
Above 1500 to 2250 50 200 10
Above 2250 to 3000 50 200 10
Above 3000 to 3750 50 200 10
Above 3750 50 200 10

Step 2:

To take an example, say, your plot size is 300 sq. yards. Convert 300 sq. yards to sq. meters by multiplying it by 0.83. After conversion 300 sq. yards comes out to be 250 sq. meters.

For a 250 sq. meters plot in Delhi the FAR = 300 (as checked from the table).

FAR = (Total area of all floors * 100)/ Plot Area

Therefore, Total area of all floors = (FAR*Plot Area)/100

Total area of all floors for 300 sq. yards = (300*300*9)/100 = 8100 sq. ft.

(Factor of 9 has been used to convert plot size from sq. yards to sq. ft.)

Step 3:

If you are planning to consume the full FAR of your plot in Delhi then according to the Delhi By Laws you can only build 4 floors. Therefore the per floor coverage area comes out to be 8100/4 = 2025 sq. ft.

What is FAR?

FAR or floor area ratio is the ratio of the gross floor area, that is the building’s total floor area, to the plot area, that is the piece of land, on which the building is constructed. Therefore, the formula can be written as: FAR = gross floor area/area of the plot.

If the FAR is higher, that means that the construction would be denser, which is commonly seen in urban areas. FAR guidelines can differ from one locality to another and are decided by the municipalities and the same is the case for Delhi.

Since the structure of Delhi like any city has limited capacity, it is ideal to not put additional stress on the land beyond its capacity. This is where FAR comes in to provide the ‘safe load’ factor.


Floor area ratio (FAR) can sometimes also be called floor space ratio (FSR), floor space index (FSI), site ratio or plot ratio.

In India, both floor area ratio (FAR) and floor space index (FSI) is used. To clarify the difference between the two-FAR is a ratio, while the latter, FSI, is an index. Index numbers are values expressed as a percentage of a single base figure. Thus, an FAR in Delhi of 1.5 is translated as an FSI of 150%.

Practical application of FAR

To explain the concept of Floor Area Ratio (FAR), we will take the help of an example. An FAR of 100 means that, as a homeowner in Delhi, you can build a one-story building on your plot or a two-story building on half your plot. FAR of 200 means that you can build a two-story building on your plot or a four-story building over half of your plot, and so on.

To further explain our previous example, if you have a 300 sq. yard (250 sq. m) plot in Delhi, then the FAR (as checked from the table) comes out to be 300. That means that you can build 3 floors with 100% of the area, i.e. 2691 sq. ft (250 sq. m) or 4 floors with ¾ (75%) of the area, i.e. approx 2025 sq. ft. (187.5 sq. m).

How does defining the FAR of Delhi benefit its citizens?

Every city is just like a structure and therefore is constrained by the capacity it can withstand. If you go beyond this capacity then it can lead to various issues. The same goes for Delhi.

FAR for Delhi defines this load-bearing capacity for the city to maintain the general well being of the citizens based on a lot of factors such as the ability to cope with natural disasters, etc.

The concept of floor area ratio is used by the government to divide the land into zones so that urban density can be restricted. It further puts a limit on the persons allowed in a building. FAR is also commonly used by architects and construction workers to accurately decide the building design and structure.
