Floors & Tiles Calculators

Estimate the materials for a new floor from the base layer to the finished surface. Choose flooring, carpet or tile to work out the main quantity, then use the supporting calculators for underlayment, leveling compound, adhesive or grout. Measure each part of an irregular room separately and keep the units consistent when adding areas. Product coverage, tile size, joint width and cutting waste all affect the final order. The tools below explain which details they use and where an allowance applies. Check the manufacturer's instructions for thickness and coverage before purchasing, especially when preparing a subfloor or installing floor heating.
