Are You Confused About Carpet Area, Built-up Area, and Super Built-up Area?


These terms can often lead to confusion. Below is an explanation of these commonly used terms by builders, developers, and real estate agents.

Carpet Area:

As defined by the Real Estate Regulation and Development Act (RERA), carpet area refers to “the net usable floor area of an apartment, excluding the space taken up by external walls while including the area occupied by internal partition walls.”

Carpet area represents the usable space within a property, excluding wall thickness. It indicates the area where a carpet can be placed, providing a precise measurement of the space available for residential or commercial purposes. To calculate the carpet area, one must measure the internal dimensions of the property.

To measure the carpet area, you can utilize either a tape measure or a laser measuring device. This process involves measuring the distance between the walls and deducting any extensions such as columns or bay windows from the overall area.

In contrast, it is usually the responsibility of the developer or builder to handle the calculations related to built-up and super-built-up areas.

The carpet area is defined as the section of your apartment or home that is enclosed by its walls and can be covered with carpeting. This area represents the usable space where you can arrange furniture, move around comfortably, and fully enjoy your living space.

Understanding the carpet area gives potential buyers a clear picture of the actual living space available.

Built-Up Area and Super Built-Up Area

The Built-Up Area refers to the total area of a property, which includes the carpet area, walls, balconies, and additional spaces such as corridors and lobbies.

This measurement takes into account the thickness of the walls and typically exceeds the carpet area by approximately 10-20%.

The super built-up area, which is larger than the carpet area, includes common areas and is often used for pricing and cost allocation. This measurement is crucial for determining the selling price, property tax evaluations, and maintenance charges. Buyers should be aware that the super built-up area may include spaces that are not solely for their exclusive use.
