How it works
Boxes = floor area x (1 + extra %) / square feet per box, rounded up.
How much extra?
Straight plank runs in plain rooms need the least. Diagonal layouts, herringbone and rooms with many doorways need more. Keep a box after the job for future repairs.
Before you start
Let flooring acclimate as the maker’s instructions say, and check that every box comes from the same lot.
