Frequently asked questions
How many boxes of laminate flooring do I need?
Take your room square footage, add about 10% for waste, and divide by the box coverage. A 12×12 room (144 sq ft) with 20-sq-ft boxes needs about 8 boxes; a 10×12 room about 7.
How many square feet are in a box of laminate?
Laminate boxes usually cover 18–24 sq ft depending on plank size — around 20 sq ft is typical. Wider or thicker planks cover less, so check the box label for your exact product.
How much waste should I add for laminate?
Plan 10% extra for straight installs and 15–20% for diagonal or herringbone layouts and rooms with lots of corners. Order in one batch so the lots match, and keep a spare box for repairs.
