Carpet Area vs Super Area vs Built-Up Area: Explained for Buyers
Updated 2026-10-18
Under RERA, sale is based on carpet area, yet many brochures quote super area.
Carpet area
The usable floor area inside the walls, including internal partitions but excluding balconies and common areas.
Built-up and super area
Built-up adds wall thickness and balconies. Super area adds a share of common areas.
Compare properly
Always compute price per sq ft on the same basis. A flat quoted at, say, 2,700 sq ft super area has a smaller carpet area, so ask for both.
