What is not included when the square footage of your house is calculated?
In general, areas like staircases and closets count as finished square footage. Spaces like garages, threeseason porches and unfinished basements or attics are not included in the square footage of a house.
What does total square footage mean?
Gross Square Feet is the total area of enclosed space measured to the exterior walls of a building. This is an umbrella term that includes everything in a facility, even unusable spaces (think areas in between walls). It's the total space a facility takes up regardless of whether or not the space is used.

Frequently Asked Questions
Where do I find the square footage of my condo?
Generally, condos are measured inside wall to inside wall without counting the width of the wall. For townhomes, exterior measurements are used, but with an estimate for half the width of the common wall counted in square footage.
Do roofs count as square footage?
How do architects calculate square footage?
Measure the length and width of the building's walls. Multiply the length and width measurements to find square footage. Remember to multiply the square footage times the number of floors in the building if your facility has more than one floor.
How do you calculate construction area?
To calculate the square feet for house construction, all you have to do is multiply the length and width of the area. For example, if the length and breadth of the plot are 40 feet by 30 feet respectively, the square footage will be 1200 sq ft.
How do you calculate construction costs?
What do you include when calculating square footage of a house?
How do you find the square footage of a round house?
Circle. If all or part of the room is rounded, you'll need to calculate the area by using the formula for the area of a circle, which is the square of the circle's radius (half its diameter) multiplied by pi. For partially circular rooms, calculate a complete circle area, then divide the area accordingly.
Do walls count as square footage?
Calculations for the square footage of a home are taken from the outside dimensions of the structure (so exterior and interior wall thickness is included).
FAQ
 How do you calculate materials to build a house?
Calculate Quantity of Materials
It's easy to figure out – simply take the total amount of square feet that were measured for the project, then divide the total amount of square feet by the coverage rate of the material.
 How do you calculate timber framing?
 With these two numbers, the formula is pretty simple:
 Number of studs needed = (Wall Width / OnCenter Spacing)+ 1.
 Plate studs needed: (Wall Width / Stud Length) * 4.
 Total Studs * (Waste Percentage / 100 + 1)
 How do you calculate timber quantities?
To work out your pieces you need to divide the number of lineal meters by the length you want to use and round the number up to the nearest 0 decimal place. E.g. if it comes out at 47.12 pieces you'll need 48. The formula is: Number of Pieces = lineal meters / length of board (rounded to zero decimal places).
 How do I figure out how much wood I need for a project?
Board Footage. TIP: To calculate board feet: rough standard thickness X actual width X actual length divided by 144. Use the thickness of the material you intend to start with, not end with. For example, the 3/4″ top will start from 4/4 lumber.
 How do I figure out how much lumber I need to build a house?
To keep it simple and stick to a good average, say that 6.3 board feet are required for every square foot of house. So, a 1,000 square foot home would need 6,300 board feet to complete, while 12,600 board feet would be necessary for a 2,000 square foot home.
 What is the square rule in timber framing?
Square rule framing, on the other hand, relies on greater uniformity. Rather than cutting joints so that one timber matches another, the timbers are formed to match a uniform standard at the joint. This meant that timbers that performed the same function in a building became interchangeable.
 What is the difference between total square footage and living square footage?
 Living square feet includes all of the air conditioned living area. Total square feet includes living square feet + porch + outdoor area + garage.
 How is square footage calculated when building a house?
If the property is a perfect rectangle, simply measure the length and width and multiply those two numbers together. For example, if your onestory house is 60 feet wide by 40 feet long, then your property is 2,400 square feet (60 x 40 = 2,400).
What is included in total square footage construction
What is the difference between gross square footage and net square footage of a building?  Gross square footage (GSF) is the total space a building takes up. It includes all of the area inside the building including unusable space between walls. Net square footage (NSF) includes only the areas of the building that are accessible by the user or tenant. 
What is considered livable square footage in a house?  When house plan sellers refer to Total Living square feet, they are referring to the “living area” of the home. This can be thought of as the area that will be heated or cooled. It is called the living area because this is where you spend your time. An attic, while a useful storage area, is not living space. 
How do I estimate the size of my roof?  Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof's pitch. (1,200 x 1.05 = 1,260 square feet.) 
Is a roof the same square footage as a house?  If your home has sections, you'll need to get the square footage of each section and add them together. Keep in mind this is a general estimate. Your home's square footage is typically slightly smaller than your roof's square footage. To get a more accurate number, factor in roof pitch and overhang. 
How many squares does it take to roof a 2000 square foot home?  20 roofing squares To put it simply, the term “roofing square” refers to 100 square feet of roof. For instance, a 2,000squarefoot roof equals roughly 20 roofing squares. These numbers are useful to know because many contractors use the term “cost per square” when they give a project estimate. 
How do you calculate a 4 12 roof?  Measure the height from the roof or rafter to the level 12 inches away from where it meets the surface. This measurement will be your rise. Display this measurement as a ratio of rise over run. For example, if your roof rises 4 inches over a run of 12 inches, then it has a roof pitch of 4:12. 
Can I measure my roof online?  Simply use iRoofing to measure roofs from satellite, aerial drone or blueprint imagery and quickly create your own report. There's no cost per roof measurement and every membership includes unlimited access for three devices.

Simply multiply the length and width of each rectangular plane, and then add the combined area of the hips. Then multiply this number by the roof's slope factor, and then multiply this final result by 1.10 to allow for error.
 What is the construction takeoff process?
In construction, a takeoff is the process that contractors use to figure out the exact quantity of materials needed for a specific project. Also known as a material takeoff or a quantity takeoff, a construction takeoff is an important step in producing an accurate estimate for a project's cost.
 What are lumber take offs?
Framing takeoff means a basic count of the framing lumber. It is the first step in estimating construction materials for a new residential or construction building.
 How do you calculate framing takeoff?
To estimate the framing materials for each window and door opening, use the total width of the opening plus 7 inches. For example, for a 36inch wide door, you need two pieces of 2x12 at 43 inches and one piece of plywood at 11 1/4 inches (the actual width of a 2x12) by 43 inches.
 What is the best way to perform the quantity takeoff?
Preparing a quantity takeoff involves converting blueprints into data or taking off quantities from drawings. It begins with counting the materials the project needs and converting them into a cost, which is then used in creating a quote or it can be used to calculate the project's budget.
 What is another name for construction takeoff?
Construction takeoff is also known as material takeoff or construction materials takeoff. The phrase “takeoff” refers to an estimator taking each of the required materials off a blueprint.
