Built-up Area Calculator

Built-up area is calculated by adding your apartment's carpet area to its internal partition walls. Internal walls include all walls that separate different rooms and spaces within your apartment but exclude external perimeter walls. Wall area typically represents 10-12% of carpet area, though this varies based on apartment configuration and number of rooms. Built-up area is the middle measurement between carpet area (smallest) and super built-up area (largest). Understanding this helps you get a complete picture of what you own versus common areas. In property valuations, built-up area is less commonly used compared to carpet area or super built-up area, but understanding it clarifies the relationship between different area measurements. This calculator helps you compute built-up area from carpet area by adding an appropriate wall percentage.
