These Terms of Use apply when you visit or use Woodworking Calculator at woodworkingcalculator.org, including its calculators, explanatory material, and downloadable reports. By using the site, you agree to these terms. If you do not agree, do not use the site.
Use of calculators and results
The calculators provide estimates or arithmetic results for the specific inputs and method shown by each tool. You are responsible for entering appropriate values, selecting the correct units, and checking the result against the actual material and project. Outputs may be rounded and may not include waste, saw kerf, defects, grain direction, moisture movement, hardware clearances, installation conditions, or other factors unless the calculator expressly includes them.
A linear cut-list calculation is not a two-dimensional sheet-nesting optimization unless the relevant tool explicitly states otherwise. A cost estimate is based on the prices and quantities supplied; it is not a supplier quote or promise of current market pricing.
No professional or project-specific advice
Site content is for general informational and planning use. It is not engineering, architectural, construction, safety, code-compliance, or project-specific design advice. It does not replace manufacturer instructions, applicable requirements, direct measurements, or qualified professional review when those are needed. Do not rely on a calculator result as the only basis for cutting, purchasing, installation, or a safety decision.
Acceptable use
Use the site lawfully and do not interfere with its operation, attempt unauthorized access, submit malicious code, or use automated requests in a way that disrupts the service. Do not misrepresent a result as a certified inspection, professional approval, supplier quote, or endorsement by Woodworking Calculator.
Availability, changes, and external links
Calculators and other site features may be changed, unavailable, or removed. The site may correct or update its methods and explanations. Links to other websites are provided for reference where present; Woodworking Calculator does not control those sites or their content.
Site content
Unless a page states a different license or permission, do not republish substantial portions of site text, calculator interfaces, or downloadable materials as your own. This does not limit uses allowed by applicable law. Contact admin@woodworkingcalculator.org to ask about reuse.
Disclaimers and limits
The site is provided on an “as available” basis. To the extent permitted by law, Woodworking Calculator makes no promise that every tool will be uninterrupted, error-free, or suitable for every project, and disclaims warranties that may lawfully be disclaimed. To the extent permitted by law, Woodworking Calculator is not liable for indirect or consequential loss arising from use of the site or reliance on a result. Nothing in these terms excludes a right or remedy that cannot legally be excluded.
Updates and contact
These terms may be updated when the site changes. The date above identifies the latest revision. Questions about these terms can be sent to admin@woodworkingcalculator.org.
