Question 1

How do you calculate square footage?

Accepted Answer

For a standard rectangular room, simply measure the length and width in feet, and multiply them together. For example, a room that is 10 feet long and 12 feet wide has a square footage of 120 sq ft (10 × 12 = 120).

Question 2

How do I calculate square footage if my measurements are in inches?

Accepted Answer

First, divide your inch measurements by 12 to convert them to feet. Then multiply the length by the width. Alternatively, you can multiply the inches together to get square inches, and then divide by 144 to get square feet.

Question 3

Why do I need to know square footage?

Accepted Answer

Knowing the square footage is essential for home improvement projects. You need it to estimate how much flooring (hardwood, carpet, tile) to buy, how many gallons of paint are needed for walls, or how much fertilizer is required for a lawn.
