Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Net area = room area − excluded area. Order area applies the waste allowance. Cartons = round up (order area ÷ carton coverage).
