Calculating the square footage of a house is not always easy. You see, each space within the home must be added into the entire area in order to gain an accurate estimate of the square footage of the entire home. When finding the square footage of a house many people wonder, “Does the garage count as square footage?” or “Does the basement count as square footage?” You do not need to include these because while the ANSI (American National Standards Institute) created guidelines on how to calculate the square footage of a house, there are no official laws for the process. However, under their standards garages, pool houses, and guest houses all require a person to leave the finished area of the main house to gain access, therefore, they are not included in the square footage on an MLS listing.

Covered porches, finished attics, stairways, closets, and the heating and cooling system are included in the square footage of a home. But how can I find that number?

A Guide to Calculating the Square Footage of A Home

You can use this basic guide to figure out how to calculate square footage of a house. Then if you have difficulty applying it to specific areas in your home, or to other types of property, you can use the additional formulas below to find exactly what is included in the square footage of a house.

Conversion Chart to Calculate Square Footage:

• Square Feet to Square Yards
• multiply ft2 by 0.11111 to get yd2
• Square Feet to Square Meters
• multiply ft2 by 0.092903 to get m2
• Square Yards to Square Feet
• multiply yd2 by 9 to get ft2
• Square Yards to Square Meters
• multiply yd2 by 0.836127 to get m2
• Square Meters to Square Feet
• multiply m2 by 10.7639 to get ft2
• Square Meters to Square Yards
• multiply m2 by 1.19599 to get yd2

You can use any measurement (inches, centimeters, etc.), and then calculate the area in square inches, or centimeters. However, you will always need to deliver your final answer in the form of square feet. Remember: if you are measuring a square or rectangle area, multiply the length by the width (Length x Width = Area), and if you need a calculation for other shapes, use an alternative formula to find the area (Area (ft2) = Square Footage).

## How-To Convert Measurements to Feet

In order to find an accurate measurement for your home, and convert it into square footage, you will need to follow these steps:

• Measure the sides of the area of the home, including the inside of every room.
• Convert all of those measurements into feet (ex: if you measured in yards, multiply by 3 to get the measurement in feet).
• Calculate the area as square footage.
• Convert square inches, square feet, square yards, and square meters.
• Call the offices of Jeff Barchi to talk to an experienced real estate professional.

## You may need a variety of footage calculations in a single home. Use these square footage formulas to calculate different areas of square footage. NOTE:Pi = 3.14

• Square Area. Using measurements in feet: Area (ft2) = Side Length x Side Length.
• Rectangle Area. Using measurements in feet: Area (ft2) = Length x Width.
• Rectangle Border Area. Using measurements in feet: Inner Area (ft2) = Length x Width, Total Area (ft2) = (Length + (2 x Border Width)) x (Width + (2 x Border Width)), Area (ft2) = Total Area – Inner Area.
• Circle Area. Using measurements in feet: Area (ft2) = Pi x (Diameter/2)^2.
• Triangle Area. Using measurements in feet: Area (ft2) = (1/4) x square root[ (a+b+c) x (b+c-a) x (c+a-b) x (a+b-c) ].
• Trapezoid Area. Using measurements in feet: Area (ft2) = ((a + b) / 2 )h.
• Circle Border Area. Using measurements in feet: Outer Diameter = Inner Diameter + (2 x Border Width), Outer Area (ft2) = Pi x (Outer Diameter/2)^2, Inner Area (ft2) = Pi x (Inner Diameter/2)^2, Area (ft2) = Outer Area – Inner Area.
• Annulus Area. Using measurements in feet: Outer Area (ft2) = Pi x (Outer Diameter/2)^2, Inner Area (ft2) = Pi x (Inner Diameter/2)^2, Area (ft2) = Outer Area – Inner Area.

NOTE: A Circle Border and an Annulus are the same, however, they are measured differently. The Circle Border and Annulus are the same, but they are measured differently.
