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. The allowance is applied before veneer boxes and mortar bags are rounded up.
FAQ
Stone Veneer Calculator questions
Are corner pieces included?+
No. Measure outside corners separately and follow the supplier’s linear-foot or linear-metre coverage.
Should I deduct every opening?+
Deduct large doors and windows, but many installers leave small penetrations in the allowance.
Does the estimate include lath?+
No. Lath, fasteners, membranes and flashing are separate system components.
