Flooring Calculator FAQs
Unlike basic calculators that just multiply length × width, this tool applies statistical methods to account for measurement errors, material waste patterns, and price variations. It provides confidence intervals rather than single-point estimates.
Flooring prices vary between suppliers, brands, and batches. By entering multiple price samples, the calculator can determine the true average cost with statistical confidence. This prevents underestimation from using a single price point.
Waste factors are based on industry standards: 5-10% for rectangular rooms, 10-15% for rooms with obstacles, and 15-20% for diagonal layouts or complex patterns. These percentages account for cutting waste and pattern matching.
Yes, the statistical methods are suitable for both residential and commercial projects. For large areas, consider using more price samples (5-7) and the 95% confidence level for optimal accuracy.
