Popular Calculators
Most requested tools for construction material calculations
Concrete volume
Estimate ready-mix volumes for slabs or cylinders with waste.
We compute geometry in meters to obtain cubic meters (m³) and convert to cubic yards for imperial projects.
Paint coverage
Calculate wall area minus openings with coats and country coverage defaults.
Wall perimeter × height gives gross area. Openings are subtracted, multiplied by coats, then divided by coverage (m²/L).
Flooring & planks
Find total area and required packs for laminate, vinyl, or hardwood.
Room area (L×W) plus waste is divided by pack coverage from local suppliers.
Tile planning
Calculate tile quantities with optional diagonal layout waste.
Surface area plus waste divided by single tile area yields tile count. Diagonal flag boosts waste.
Roof bundles
Slope-adjusted roof area and bundle counts with ventilation waste.
Projected area divided by cos(angle) equals slope area. Waste + bundle coverage map to bundle count.
Drywall sheets
Wall area plus waste divided by preferred sheet size.
Perimeter × height minus openings yields wall area. Sheet size from country defaults handles board formats.
Wallpaper rolls
Strips per roll and total rolls with pattern allowance.
Roll length divided by wall height + allowance gives strips per roll. Perimeter / roll width yields needed strips.
Brick & mortar
Wall area times regional brick density yields bricks and mortar volume.
Wall area × bricks per m² returns quantity. Mortar per m² estimates cement-sand mix volume.
