No, the carpet area is not necessarily the same for all rooms in a property. The carpet area is the actual usable area within the walls of your home, excluding the thickness of the inner walls. Therefore, it can vary depending on the size and layout of each room. Larger rooms will have a larger carpet area whereas smaller rooms will have a smaller carpet area. Also, rooms with different purposes, such as bedrooms, living rooms, kitchens, and bathrooms may have different sizes. So, it means they all have different carpet areas. Therefore, you must properly measure each room to find the exact carpet area.
