How to Calculate Square Footage
Learning how to calculate square footage is useful for flooring, paint, drywall, tile, and many other home improvement projects. Once you know the basic formula, it becomes very simple.
The Basic Formula
The standard formula for square footage is:
Square Footage = Length × Width
If a room is rectangular, you simply measure the length and width in feet, then multiply them together.
Example
If a room is 12 feet long and 10 feet wide:
12 × 10 = 120 square feet
What If the Room Is Not a Perfect Rectangle?
If a room has an unusual shape, divide it into smaller rectangles. Measure each section separately, calculate the square footage of each one, and then add them together.
Why Square Footage Matters
Square footage is used to estimate material quantities for flooring, paint, drywall, tile, carpeting, and other renovation work. A more accurate measurement can help reduce waste and improve budgeting.
