Material planning

Flooring & Tile Calculators

Plan tile and flooring materials for DIY projects with calculators that turn project and product measurements into purchase-ready estimates.

Available calculators

Calculate square footage for rooms, floors, walls, and multiple rectangular areas, with optional exclusions and unit conversions.

Estimate flooring boxes from project area, waste allowance, exact package coverage, and optional material price.

Estimate tiles, sheets, whole boxes or cases, waste allowance, openings, and material cost for floors, walls, and backsplashes.

Estimate grout volume, product weight, whole packages, extra allowance, and optional material cost from manufacturer coverage or tile-joint geometry.

Estimate thinset mortar packages from tile area and manufacturer coverage for your trowel notch, with whole-package rounding.

Estimate broadloom carpet from room dimensions and roll width. Compare roll layouts, seams, linear roll length, and roll-layout extra.

Estimate vinyl flooring cartons from coverage, extra allowance, optional pieces, and material cost.

Estimate flooring underlayment rolls or packages from project area, extra allowance, published product coverage, and optional material cost.

Estimate plywood or OSB subfloor sheets from floor area, nominal panel size, extra material allowance, and optional sheet cost.

Estimate self-leveling compound bags from floor area, average pour thickness, and published product coverage at its reference thickness.

Turn room or surface measurements into the coverage required for a project, including openings where a calculator supports them.

Apply a planning allowance when cuts, breakage, layouts, or irregular areas mean the exact measured area is not enough.

Translate required coverage into purchasable boxes, cases, pieces, or sheets when product data supports it, then estimate material cost.
