Frequently asked questions
How many boxes of vinyl plank flooring do I need?
Divide your room square footage (plus about 10% waste) by the coverage printed on the box. A 12×12 room (144 sq ft) with a 24-sq-ft box takes about 7 boxes; a 20×20 room needs about 19.
How many square feet are in a box of vinyl plank?
Most LVP boxes cover 20–30 sq ft, with 24 sq ft common. Thicker, wider, or rigid-core (SPC) planks often have less per box, so always confirm the coverage on the label before buying.
How much extra vinyl plank should I buy for waste?
Add 10% for a standard straight installation, 15% for diagonal, and 20% for herringbone or chevron patterns. Buy it all in one batch so the print/dye lots match, and keep a spare box for future repairs.
