Calculate flooring packs and waste allowance for a room.
Waste depends on the layout rather than the material, because diagonal and herringbone patterns produce angled offcuts that cannot start the next row. Packs are whole units, so the result rounds up. Keeping the spare material after installation matters more than minimising it, since matching a discontinued batch for a later repair is usually impossible.
