Area = Length × Width (sq ft)
With Waste = Area × (1 + waste%)
Boxes = ⌈With Waste ÷ Coverage per box⌉
Straight lay: 10%. Diagonal or herringbone: 15%. Complex rooms with many cuts: 15–20%.
Varies by product — typically 20–30 sq ft per box. Check the box label.
Measure the longest length and widest width. Multiply for sq ft. For odd shapes, divide into rectangles.
Laminate and floating hardwood need underlayment. Glue-down and nail-down products usually don't.
