What else matters here
A hundred and forty square feet of floor, which is never the number you buy. Flooring is bought in whole cartons with a waste allowance on top.
Ten percent is the usual allowance for a straight lay in a simple rectangle, and it covers the end cuts, the piece that starts the next row and the boards culled for damage. Go to fifteen percent for a diagonal or herringbone layout, and add more for a room with a lot of jogs and doorways. Then divide by the square feet in a carton, which is printed on the box and is commonly 20 to 24 for plank and 15 to 30 for tile, and round up. A hundred and forty square feet plus ten percent is 154, which is seven cartons at 22 square feet.
What this calculator assumes
- Length times width, times how many areas are that size. For an L shaped room, split it into two rectangles and run this twice.
- Square yards are square feet divided by nine, which is how carpet is still quoted in much of the country.
