1. Carpet Area

Carpet area refers to the actual usable area within the walls of your apartment. Think of it as the space where you can lay a carpet, hence the name. It includes the bedrooms, living room, kitchen, and bathrooms, but excludes the thickness of the inner walls, balconies, and common areas like staircases, elevators, and lobbies.

2. Built-up Area

Built-up area is larger than the carpet area. It includes the carpet area plus the thickness of the internal walls and the areas occupied by balconies and terraces (if any).

3. Super Built-up Area

Super built-up area takes the built-up area and adds a proportionate share of the common areas like staircases, elevators, lobbies, and other amenities. This is often referred to as the "saleable area" since many developers price the property based on this area.
