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 perimeter = room perimeter − doorway deductions. Multiply by room count, add waste and round to stock pieces and full packs.

FAQ
Baseboard Molding Calculator questions
Should closets be included?+
Include every wall edge receiving the same molding, including closets when they are part of the scope.
Why use long stock lengths?+
Longer pieces reduce joints but may cost more or be harder to transport. Enter the actual stocked length.
Does this include shoe molding?+
No. Estimate shoe or quarter-round separately when used.
