MetandumFind a calculator ⌕My projectsMap floor sections and measure wall areas before estimating materials.
Divide your measured floor into rectangles whose edges touch. Positions share a common origin. Example dimensions are shown initially; replace them. This page does not save automatically.
Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.
Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.
Use only areas that require no flooring. Each exclusion must fit entirely within one section.
Net floor area: 12 m² (gross 12 − exclusions 0).
Record this net area for material coverage. The flooring room planner accepts rectangular rooms; use actual measured rectangles there. This irregular floor is not converted into invented room dimensions.
Enter actual wall lengths once, including outer boundaries and any walls you intend to cover. We do not sum floor-section perimeters: shared edges are not walls.
Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.
Measure only the area, length or quantity to deduct, in the unit shown. Keep this consistent with the surface being calculated.
For varying heights, calculate separate wall groups. Opening area must not include the same opening twice.
Net wall area: 35 m²
Enter your chosen product specifications. Only the measured net wall area is transferred; confirm all fields in the paint calculator.
Use the usable coverage or mixed yield printed on your product label for the stated application. Do not substitute bag weight for finished volume.
Use the actual usable quantity or dimensions of the product you intend to buy. Check the label and the unit shown here.
Enter your own allowance. Presets are input shortcuts, not a construction recommendation.
Enter valid product coverage, container size, coats and allowance to prepare the calculator link.
