Wall area calculator
Name each wall, then deduct doors, windows and other openings.
Walls
Openings to deduct
If the openings you enter add up to more than the walls, the calculator says so rather than quietly returning zero — that is almost always a unit or count mistake.
Area calculator
For ceilings, floors and single surfaces.
Estimate
Coating quantity estimator
Coating quantity estimator
Run it once per layer — putty, primer and topcoat have different coverage rates and different coat counts.
We do not supply the coverage figure, the coat count or an allowance. Coverage varies by product, surface porosity, preparation and application method, and is stated on the product. Coat count follows the product system. Allowance depends on surface, application, container sizes, touch-up needs and project conditions. The calculation is shown with the result so you can check it.
Project
Multi-room project builder
Multi-room project builder
Choose the project unit once. Every room stores it, and every figure is shown with its unit.
Gross wall area is the perimeter times the height. Doors and windows are deducted only where you enter a size. An opening left blank is recorded as unmeasured and is not deducted — no nominal dimension is assumed.
