How to Calculate the Square Footage of the Walls and Flooring of a Room
Updated: Jun 7
Calculating the square footage of a room's wall and flooring is an essential step in planning for any home renovation project. Knowing the exact square footage will help you estimate the cost of materials, including paint, wallpaper, flooring, and tile. Here are the steps to calculate the square footage of a room's wall and flooring:
Calculating Wall Square Footage
Measure the height and width of each wall in feet. If the room has irregularly shaped walls, divide them into rectangular sections and measure each section separately.
Multiply the height and width measurements together for each wall to get the total square footage of that wall.
Add the square footage of each wall together to get the total square footage of the room's walls.
Calculating Flooring Square Footage
Measure the length and width of the room in feet.
Multiply the length and width measurements together to get the total square footage of the room.
Subtract the square footage of any areas that will not be covered by flooring, such as built-in cabinets or appliances.
Divide the total square footage by the square footage of each package of flooring to determine the number of packages needed.
Calculating the square footage of a room's wall and flooring may seem like a daunting task, but by following these simple steps, you can accurately estimate the amount of materials needed for your renovation project. Remember to measure each wall separately, subtract any areas that won't be covered by flooring, and always round up to ensure you have enough materials. With these calculations, you'll be well on your way to a successful renovation project.
