What else matters here
A hundred and forty square feet of floor. Flooring is bought in whole cartons with a waste allowance on top.
Ten percent covers the offcuts at the ends of rows in a plain rectangular room. Go to 15 percent for a diagonal or herringbone lay, and 20 if the room is cut up with closets and angles.
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.
