Laminate Flooring Calculator
How many boxes of laminate for a room? Enter the room and plank size, the square feet per box from the label, and the waste allowance — get planks, boxes and cost.
Printed on the box — commonly 18–25 sq ft.
Laminate for 120 sq ft
7 boxes — 53 planks · 132 sq ft to buy
$330 — estimated material cost at $2.50 / sq ft
Exact area: 120 sq ft (11.1 sq m). Each plank covers 2.50 sq ft. With 10% waste, buy 132 sq ft — that is 7 boxes at 20.0 sq ft per box. Add underlayment and matching trim; laminate needs an expansion gap of about 3/8 in at every wall.
Estimate. Confirm the square feet per box on the actual box label and the current shelf price before ordering.
Formula used: Square feet to buy = length × width × (1 + waste%). Planks = sq ft to buy ÷ plank area. Boxes = sq ft to buy ÷ sq ft per box, rounded up.
How this estimate works: Laminate is sold by the box, and boxes are sold by the square foot, so the tool works in square feet first: room area plus a waste allowance for cuts. Plank count comes from dividing by one plank's area, and box count from the figure printed on the box — which varies by product, so it is an input, not an assumption.
