How do you determine the square footage of a house?
First you measure the width and then the lenght then multiply it. length times width.
Depending on what you need the information for, you can get a rough idea by measuring the entire outside of the house. Then multiply the length of the house times the width of the house, and then double it. That will give you a very basic idea. If you need the exact square footage, you could purchase a copy of the blueprints from the building department.
House dimensions are measured in Square Feet. How many square feet are in a house depends on the size and the layout of the house. For example, many houses do not have equal footage of all outside walls. Also, square footage of each room is smaller that the footage of outside walls, to subtract for walls, fireplaces, etc. Also, any outdoor additions (porches, patios) are not counted in sq. footage of the house.
Unless the room is a perfect square (length and width are the exact same) you cannot determine the length and width without knowing one of the two first. If you know one of these, simply divide the square footage by the measurement that you do know. If the room is a perfect square, the length and width would both be the square root of the square footage.
Yes and no. If the home is a one story, then obviously whatever the square footage of it is, is what square footage of land is underneath it. Now, if you have a two story home you wouldn't be able to use the square footage. You may ask why is that. Because now your square footage is equal to up and down stairs. In turn this will double the square footage. I wanted to add…
Determine length (linear) and how wide is it. Multiply the length times the width and this will give you the total area or square footage. Here is another example: A product is sold by the 20 foot long (linear feet) roll. The specifications state that the product is 2 foot wide x 20 feet long. It is in fact 20 ft. x 2 ft. wide or 40 square feet per roll.
In Southwest Florida we generally start with the square footage of a home to determine the price, that is then adjusted by the age, the quality of the construction and the number of bedrooms, bathrooms. Also the type of land will figure into the equation whether it is waterfront, golf course, condo, what type of view is afforded, etc. While starting with square footage as a base there are many other variables to consider. No…
Model each floor of the house with one or more rectangles, compute the area of each of these rectangles, and sum them to the total square footage. If the shape of you house if really complicated you may have to throw a triangle in there, but most houses can be approximated well enough using rectangles.
