Calculate the flooring material needed with a waste allowance.
Flooring needs a waste percentage because planks must be cut at edges and in corners. Adding that margin to the pure room area gives what to actually buy. Under-ordering flooring is expensive to fix, while a modest margin covers unavoidable cuts and a few imperfect planks.
