Use project-specific values
Where a calculator asks for coverage, yield, spacing, density, package size or price, use the value from the actual product or quote whenever possible.
Verify before ordering
Structural spans, footing sizes, guard requirements and gate hardware are project-specific and should be checked separately from quantity estimates.
