Disclaimer & Legal

All calculations provided by Measure Twice are estimates only. They are intended to help you plan your project and approximate material quantities — not to serve as precise specifications for ordering or construction.

Results should always be verified by a licensed contractor, architect, or other qualified professional before purchasing materials or beginning work. Measure Twice is not responsible for material shortages, overages, cost overruns, or any project outcomes that result from relying on our calculators.

Actual material needs may vary significantly based on room irregularities, substrate conditions, installer technique, pattern and layout choices, cutting waste, and manufacturer-specific requirements. Different products and installation methods can produce very different waste factors.

We strongly recommend purchasing a small amount of extra material as a buffer — typically 10–15% beyond calculated quantities, or more for complex layouts and diagonal patterns. The measurements and inputs you enter are your sole responsibility. Inaccurate dimensions, incorrect unit selections, or omitted areas will directly affect your results.

Measure Twice provides general estimation tools for informational and educational purposes only. Nothing on this website — including calculator results, blog articles, material recommendations, or project guides — constitutes professional engineering, architectural, structural, electrical, plumbing, or contracting advice.

For any work involving structural modifications, load-bearing walls, electrical systems, plumbing, gas lines, or other regulated trades, always consult a licensed professional who is familiar with your specific project and jurisdiction.

Local building codes, permit requirements, and zoning regulations vary widely by municipality, county, and state. Always check with your local building department or relevant authority before starting any home improvement project, even one that appears straightforward.

Measure Twice is committed to making our calculators and content accessible to as many people as possible. We aim to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA standards and continuously work to improve the usability of our site for all visitors.

If you experience any accessibility barriers while using Measure Twice — such as difficulty navigating with a screen reader, insufficient color contrast, or keyboard navigation issues — please contact us at mcallisterapps@googlegroups.com. We take accessibility feedback seriously and will work to address reported issues promptly.

We are actively working to improve accessibility across the site and welcome your suggestions. This statement reflects our current efforts and goals; it does not constitute a legal guarantee of full WCAG compliance at all times.

Affiliate commissions do not affect the price you pay — you will not be charged more for purchasing through our links. We only link to products and materials that are relevant to the calculators and project guides you are using.

Our affiliate relationships do not influence calculator results, material quantity estimates, or the recommendations we provide. Calculations are based on standard industry formulas and the inputs you supply, independent of any commercial partnerships.

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, our liability is limited to the maximum extent permitted by law. Nothing in this disclaimer is intended to exclude liability that cannot be excluded under applicable law.
