Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Coat area = door width × height × quantity × painted faces × coats. Allowance is applied before dividing by product coverage and container volume.
FAQ
Door Paint Calculator questions
Do paneled doors use more paint?+
Often yes. Profiles increase actual surface area and can reduce practical coverage.
Should the top and side edges be included?+
Add a larger allowance when painting door edges or detailed profiles.
Does this include primer?+
No. Estimate primer separately when required by the surface or color change.
