How this is calculated

length (ft) × width (ft) = square feet · ÷ 9 = square yards · × 0.0929 = square meters. For an L-shaped or multi-room space, calculate each rectangle separately and add them together.

This is a planning estimate — always confirm against your supplier and the specifics of the job before ordering.

Square footage calculator: FAQ

How do I calculate square footage?

Multiply length by width, both in feet. A room 15 ft long and 12 ft wide is 180 square feet. For a wall, use length × height.

How do I find the square footage of an odd-shaped room?

Split it into rectangles, calculate the square footage of each, and add them together. For a triangle, use ½ × base × height.

How many square feet are in a square yard?

Nine. To convert square feet to square yards — as flooring is often sold — divide by 9.
