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 wall area = wall length × height − openings. Total coat area = net area × coats. Bags = round up (coat area × waste factor ÷ coverage per bag).

FAQ
Stucco Calculator questions
Does each stucco coat use the same product?+
Not always. Scratch, brown and finish coats can use different mixes and coverage rates.
Should windows and doors be deducted?+
Large openings should be deducted, while returns and detailing can add material back.
Does this include lath and flashing?+
No. Those components require a separate wall-system takeoff.
