Flooring calculator
Flooring orders need to account for waste, packaging, and the actual layout—not just the room's raw square footage. Enter room dimensions, choose a waste allowance, and add the coverage and price printed on your flooring box. CalcForged gives you room area, the recommended order area, whole boxes to buy, and a material cost estimate. Use 10% for a simple straight lay and 15% for diagonal or herringbone patterns.
