How to Calculate Square Feet

Calculating square feet is simple when you know the length and width of an area. The most common method is to multiply the length by the width when both measurements are in feet.

Square Feet = Length × Width

For example, if a room is 20 feet long and 15 feet wide:

20 × 15 = 300 square feet

Therefore, the room has a total area of 300 square feet.

How to Calculate Square Feet of a Room

To calculate the square feet of a room, measure the length and width of the room in feet. Multiply the two measurements together. This method works for bedrooms, living rooms, kitchens, offices, garages, and other rectangular spaces.

Example:
Length = 12 feet
Width = 10 feet

12 × 10 = 120 square feet

How to Calculate Square Feet of a House

For a simple rectangular house, multiply the overall length by the overall width. If the house has several rooms or irregular sections, calculate each rectangular section separately and add the results.

Total House Square Footage = Area of Section 1 + Area of Section 2 + Area of Section 3

How to Calculate Square Feet From Inches

If your measurements are in inches, first multiply the length by the width to obtain square inches. Then divide the result by 144 because one square foot contains 144 square inches.

Square Feet = (Length in Inches × Width in Inches) ÷ 144
Example:
120 inches × 144 inches = 17,280 square inches
17,280 ÷ 144 = 120 square feet

Square Feet to Square Meters

To convert square feet to square meters, multiply the square footage by approximately 0.092903.

Square Meters = Square Feet × 0.092903

Square Feet to Square Yards

One square yard equals 9 square feet. To convert square feet to square yards, divide the square footage by 9.

Square Yards = Square Feet ÷ 9

Frequently Asked Questions About Square Feet

How do you calculate square feet?
Multiply the length of the area by its width. If both measurements are in feet, the result is the area in square feet. For example, 20 feet × 15 feet = 300 square feet.
How do I calculate square feet of a room?
Measure the room's length and width in feet and multiply them. For a 12-foot by 10-foot room, the calculation is 12 × 10 = 120 square feet.
How do you calculate square feet from inches?
Multiply the length in inches by the width in inches and divide the answer by 144. This converts square inches into square feet.
How many square feet are in a square yard?
One square yard equals 9 square feet. Therefore, multiply square yards by 9 to convert them to square feet.
How many square feet are in a square meter?
One square meter is approximately 10.7639 square feet.
How do you calculate square feet of a house?
For a rectangular house, multiply the length by the width. For a house with multiple sections, calculate the square footage of each section and add them together.
What is the formula for calculating square feet?
The basic formula is Square Feet = Length × Width, when both measurements are expressed in feet.
Can I calculate square feet for an irregular room?
Yes. Divide the irregular room into smaller rectangular or square sections, calculate the square footage of each section, and add the areas together.
What is the difference between square feet and square footage?
Square feet is the unit used to measure area, while square footage refers to the total amount of area measured in square feet.
