About & Methodology

These tools turn your measurements into transparent planning estimates. Geometry, waste rates, package coverage, and costs remain visible so you can check the result.

Formulas and examples

Area and layout formulas are selected for the stated room shapes and units. Worked examples are tested against the same deterministic calculator functions; installation conditions can still change a field result.

Sources and limitations

Guides cite primary manufacturer or standards resources where appropriate. Editorial dates change only when claims are substantively reviewed. Results are estimates, not site measurements, quotes, installation instructions, or specialist advice.

Privacy

Measurements, prices, and layout choices are processed in your browser. This static site does not provide project accounts or a calculator upload database.
