Two hundred and eighty square feet plus ten percent is 308, fourteen cartons, 315 bought.
What this calculator assumes
- 10 percent waste covers a straight lay in a simple rectangle. Go to 15 for a diagonal or herringbone lay, and 20 if the room is cut up with closets and angles.
- Buy the whole job in one delivery. Dye lot and batch shade move between production runs, and a single replacement box six months later will not match.
