Boxes of laminate, vinyl plank or hardwood for a room.
AdvertisementA 15x12 ft living room needs 10 boxes of laminate at 20 sq ft per box, including 10% extra for cuts.
We multiply the room's length by its width, add extra for cuts (5% to 15%), and divide by the coverage printed on one box. The result is rounded up to whole boxes.
Plan 10% extra for most rooms, 5% for a simple rectangle, and 15% for diagonal layouts or rooms with many corners.
Most boxes cover 18 to 25 sq ft, depending on plank size and thickness. The exact coverage is printed on the box.
With 10% extra for cuts you need 550 sq ft, so 28 boxes at 20 sq ft per box. Check the coverage printed on your box, since it varies by product.
Usually parallel to the longest wall or toward the main window. It makes the room look larger and hides the seams between planks.
