But these numbers should be used only as a reference point. A buyer should never make their home buying decision based on square the square foot of a home. There are some situations, such as buying in a larger condo building especially newer construction with identical finishes , when buyers are particularly interested in the price per square foot.
They want to know this in relation to comparable sales. Does the size of the house seem to work for you? Note: The views and opinions expressed in this article are those of the author and do not necessarily reflect the opinion or position of Zillow.

To calculate the square feet of a rectangular area, you first need to measure two dimensions: the length and the width note that we discuss irregular shaped areas further down.
Note that the same formula applies if you measure in metric. In this case, the area will be expressed in square metres. Insert your measurements into the formula. You're going to multiply the length measurement in feet by the width measurement. This gives you the area of the space in square feet. You can also use this formula to calculate smaller areas when the area will be expressed in square inches and larger areas in square yards.
Multiply these dimensions:. Sometimes, you might need to calculate a space that's an addition to the main area or a room that isn't evenly shaped. In these situations, think of the space as separate areas. You may find it helpful to sketch out a quick floor-plan to divide the space into more regular shapes. Suppose you have a rectangular living room with a narrower dining area attached. Think of the space as being made up of a larger rectangle and a smaller rectangle. First measure the length and width of the larger section labelled A, then do the same for the smaller section labelled B.
It may be that the area you're measuring isn't square or rectangular, but triangular or circular. If this is the case our square footage calculator page has details of the measurements you will need to take, in addition to providing a tool to help you calculate your area. Measure the length and width of the second space. Let's say that the length of Space B is 20 feet 6.
Multiply the length of the second space times the width of the second space. This will lead you to find the square footage of the second space.
Measure the length and width of the third space. Let's say that the length of Space C is 20 feet 6. Multiply the length of the third space times the width of the third space. This will lead you to find the square footage of the third space. Here's how you find the square footage of Space C: Ex: 20 feet 6.
Add the square footages of the three spaces. Once you find the sum of the square footages of the three spaces, you'll know the square footage of the entire space. Method 2. Find the approximation of square footage.
If you're looking for an approximation of square footage, you can also try measuring the outside of your home and then subtracting any areas that won't be factored in to the square footage, such as the porch stairs or garage.
Ceiling and floor tiles are often one square foot in size. You can simply count these to get a close approximation of the total square footage. Find the square footage of a space that's shaped like a half-circle. If there's a part of your house that's shaped like a half of a circle, you can find the square footage of the circle by finding the area of the space as if it were a full circle and then dividing it by half.
To do this, simply measure the long line that cuts the "circle" in half to get the diameter. Finally, divide by 2 to get the area, or square footage, of the half circle. Find the square footage of a space that's almost regularly shaped.
If you're measuring a space that is almost fully a square or a rectangle, with only a small square or rectangular part missing, then measure the square footage of the entire space as if the missing part was filled in. Then, find the square footage of the missing part and subtract it from the overall square footage to find the square footage of the space. This will save you time.
