| Waste allowance | Boxes to order | With 10% waste | Left over |
|---|---|---|---|
| 5% | 4 boxes | 84 sq ft | 10 sq ft |
| 10% | 4 boxes | 88 sq ft | 10 sq ft |
| 15% | 5 boxes | 92 sq ft | 32.5 sq ft |
| 20% | 5 boxes | 96 sq ft | 32.5 sq ft |
What else matters here
Eighty square feet plus ten percent is 88, which is four cartons and 90 square feet bought. Ten square feet spare, so if this room has a closet or a bay measure it and add it.
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.
