How much flooring to buy
Laminate, vinyl, and hardwood flooring are sold by the box, each covering a set area. This calculator turns your room size and the box coverage into the number of boxes to buy, with a waste margin built in.
A 25 square metre room with boxes covering 2.2 m² each needs about 12 boxes bare, or 13 with a 10% waste allowance for cuts and the odd damaged plank. Diagonal layouts warrant a little more.

It divides area by box coverage, applies your waste percentage, and rounds up to whole boxes in your browser with nothing uploaded.
