# How do you calculate square feet?

Square footage is a measurement of the area of a room. In a simple square or rectangular-shaped room, use the formula "length times width" to calculate square footage.

1. ### Measure length and width

Measure the length and width of the room or space. Write down each number in feet and inches.

2. ### Multiply length times width

Multiple the length and width. If the measurements are seven feet and nine feet, the result of 7 x 9 is 63.

3. ### Indicate the square footage

Record the number as square footage, such as 63 square feet. An abbreviated version of this measurement is 63 Sq. Ft.
