Carpet area formula
Square feet = length × width. Square yards = square feet ÷ 9. Add waste before converting to purchasing quantity.
Planning notes
Carpet roll width and seam placement can mean you need more material than raw floor area suggests. Use this as an area estimate and confirm the final cut plan with your supplier or installer.
- Carpet is often sold by square yard in the US.
- Roll width and seam layout can affect the amount you actually need.
