Measure each area
Record room length and width in feet. Split an irregular room into rectangles, include closets and add the areas once.
Flooring planning
Flooring Calculator: Plan Materials and Installation
Start with your floor area and material choice, then connect the result to room transitions, removal and subfloor preparation.
Use the calculator
JavaScript runs this calculator. Send your measurements for a project review.
What should you measure?
Separate floor area from material allowance
For example, 12 × 10 ft plus a 4 × 3 ft closet gives 132 ft². Material allowance is added to the measured area. If a selected allowance is 10%, that example becomes 145.2 ft² before package rounding.
Check the package coverage
Use the coverage printed for the selected product. Divide the required material area by that coverage and round up to whole packages.
List work beyond the material
Include removal, disposal, stairs, transitions, trims and subfloor preparation in the installation scope.
What makes installation ready?
Existing floor and subfloor
Review the current layers, flatness, damage and moisture conditions with the installer and the selected product instructions.
Doors, cabinets and transitions
Check finished floor thickness at door openings, appliances, stair edges and adjoining rooms before selecting the installation detail.
Product and room conditions
Confirm acclimation, substrate and installation requirements for that actual flooring system.
Review the complete scope
Bring measurements, flooring samples and room photos. Your price and schedule depend on the selected materials and preparation work.
Bring your result into the project
Save the calculator result and the assumptions you entered. Add room photos and the problems you want to solve.
