- Plot (site) area is the land inside the boundary.
- Built-up area is the floor area the house covers, measured to the outside of its walls, added up over all floors.
- Carpet area is the usable floor inside the walls, usually 10–20% less than built-up area.
- Marla, bigha and kanal differ from state to state, so confirm their size locally before you compare prices.
