Carpet area
Measurement
In one line
The usable floor inside the walls — what you can actually put carpet on.
Carpet area excludes the thickness of walls and all common space. RERA requires flats to be sold on carpet area precisely because super area was being inflated. It is typically 25–30% less than built-up area.
