When calculating the square footage of a floor, it is important to account for any built-in objects such as cabinets, bookshelves, and fireplaces. These objects can take up valuable floor space and affect the overall square footage of the room. To account for these objects, measure the length and width of the object and multiply them together to get the square footage. Then, subtract this square footage from the total square footage of the room.

For example, if a room is 12 feet by 10 feet and has a built-in bookshelf that is 4 feet by 2 feet, the square footage of the bookshelf would be 8 square feet (4 feet x 2 feet). To get the total square footage of the room, subtract 8 square feet from the total square footage of the room (120 square feet) to get 112 square feet.

Subtracting Non-Floor Areas

In addition to built-in objects, it is also important to account for any cutouts or non-floor areas in the room. This can include areas such as staircases, closets, and alcoves. To calculate the square footage of these areas, measure the length and width of the area and multiply them together to get the square footage. Then, subtract this square footage from the total square footage of the room.

For example, if a room is 12 feet by 10 feet and has a closet that is 3 feet by 2 feet, the square footage of the closet would be 6 square feet (3 feet x 2 feet). To get the total square footage of the room, subtract 6 square feet from the total square footage of the room (120 square feet) to get 114 square feet.

By accounting for built-in objects and non-floor areas, you can get a more accurate calculation of the square footage of a floor. This can be helpful when determining the amount of materials needed for a renovation project or when calculating the value of a property.

Calculating Multi-Level Floors

Calculating the square footage of multi-level floors can be a bit more complicated than calculating the square footage of a single-level floor. However, with a bit of planning and some basic math skills, it can be done accurately and efficiently.

Stacked Spaces

When calculating the square footage of a multi-level floor, it's important to take into account all of the stacked spaces, such as basements or attics. To calculate the square footage of a stacked space, measure the length and width of each level of the space and multiply those numbers together. Then, add the square footage of each level together to get the total square footage of the stacked space.

For example, if a basement is 30 feet long and 20 feet wide, and the first floor above it is also 30 feet long and 20 feet wide, the total square footage of the stacked space would be 1,200 square feet (30 x 20 = 600 square feet for the basement, plus 30 x 20 = 600 square feet for the first floor, for a total of 1,200 square feet).

Staircases and Landings

Another factor to consider when calculating the square footage of a multi-level floor is the space taken up by staircases and landings. Staircases and landings can take up a significant amount of space, and it's important to include that space in your calculations.

To calculate the square footage of a staircase or landing, measure the length and width of the space and multiply those numbers together. Then, add the square footage of each staircase and landing together to get the total square footage taken up by these features.

It's important to remember that the square footage taken up by staircases and landings should be subtracted from the total square footage of the floor, as this space cannot be used for other purposes. By taking these factors into account, you can accurately calculate the square footage of a multi-level floor.
