See how many boxes of flooring you need — from the room area, the coverage per box, and a waste allowance — plus the total cost.
Buy an extra box for future repairs and keep the lot number. Laminate and vinyl plank often need a 10% cut allowance. Estimate only.
Add a waste allowance to the room area, then divide by the square footage each box covers and round up. Always buy whole boxes — and one spare box for repairs down the road.
Boxes = ⌈(area × (1 + waste %)) ÷ coverage per box⌉
10% for straight installs, 15% for diagonal, plus one spare box kept aside for future repairs.
It's printed on the label — commonly 18–24 sq ft for laminate and vinyl plank. Enter the exact figure for the best estimate.
