Plan laminate, vinyl plank, hardwood or carpet with adjustable box coverage and waste.
Results use your measurements and editable assumptions. Verify product coverage, density, waste and order rounding with the supplier before purchasing.
Order area = room area × (1 + waste percentage). Boxes = order area ÷ box coverage.
BuildCalc converts measurements to a consistent internal unit, applies your project geometry and only then adds the selected waste allowance. Packaging quantities are rounded up because partial bags, blocks or boxes usually cannot be ordered.
Flooring is purchased by coverage, often in whole boxes. Measure each room section, add the areas and set waste according to the layout, board direction and number of cuts. Use the coverage printed on the exact box because nominal package sizes vary by product.
The room area is 180 square feet. A 10% layout allowance raises the order area to 198 square feet. If one box covers 22 square feet, the order rounds to 9 whole boxes.
Simple straight layouts usually need less than diagonal or patterned work. Follow manufacturer guidance and increase the allowance for many cuts or irregular rooms.
No. Underlayment, transitions, adhesive, fasteners, baseboard and other accessories require separate measurements.
