Ahead of discussing how to calculate square feet of a house, lets define what it is. Square footage is the size of a lot or the floor space of a building or any other piece of real estate or property.
Square footage of a house matters most in real estate deals where the lender needs to verify that the property is worth what the buyer has agreed to pay.
Formula to Calculate Square Feet of a House.
First, we need to consider the shape of the structure or the floor space and make sure that the dimensions are in feet. If for instance, the structure is rectangular, we will use the formula to calculate the area of a rectangle to find its area.
Example 1:
Suppose you have a circular living room, if its floor has a radius of 4 feet, calculate the area of the floor. Since its a circular structure, we will use the formula to calculate the area of a circle to find its area.
Thus, the square feet of the house is 100.53ft² .
Example 2:
If the property is a perfect rectangle whose length is 70 feet wide by 30 feet long, calculate its area.
To find the area of a rectangle, we multiply the length by the width.
= 60 x 30
Therefore, the area of the room is 1800ft2
Example 3:
Suppose your square master’s bedroom roof measures 4 meters on one side. Calculate the area of the room if the roof and the floor are the same size.
Since its a square, we use the formula to calculate the area of a square.
Area = Side x Side
= 4 x 4
= 16m2
Then we convert the are in square meters to square feet.
1m2 = 10.7639ft2
= 16 x 10.7639
Hence the are of the room is 160.7639ft2.
