Terms of Use

By using TrustTheCalcs you agree to these terms. If you do not agree, please do not use the site.

Preliminary estimates only: not engineering advice

The calculators and content on this site produce preliminary material estimates for planning purposes only. They are not engineering, design, or professional advice, and they are not a substitute for a licensed structural or civil engineer. Do not use any result on this site for load-bearing, safety-critical, or code-compliance decisions. Reinforcement, bracing, footings, connections, seismic and wind loads, and similar design matters must be determined by a qualified professional working from your project and local code. This language is consistent with the disclaimer shown on our calculators and guides.

No warranty

The site is provided “as is” and “as available,” without warranties of any kind, express or implied, including but not limited to accuracy, fitness for a particular purpose, or non-infringement. We work hard to source every figure and to show its origin, but we do not warrant that the site is error-free or that any result is suitable for your specific situation. Nothing on this site has been reviewed or approved by a licensed engineer.

Limitation of liability

To the fullest extent permitted by law, TrustTheCalcs and its contributors are not liable for any loss or damage, including material over- or under-ordering, cost overruns, construction defects, delays, or consequential, incidental, or indirect damages, arising from your use of, or reliance on, this site or its results. You are responsible for verifying all quantities and design decisions with appropriate professionals and suppliers before purchasing material or building anything.

Acceptable use

You may use the calculators and read the content for your own estimating and educational purposes. Do not misrepresent our figures as engineered or approved values, and do not present the site as having provided professional certification of any project.

Third-party standards and links

We cite and link to third-party standards and datasheets but do not reproduce their copyrighted text. Those documents are governed by their publishers’ terms, and you are responsible for obtaining them where your work requires the full text.

Changes

We may update these terms as the site grows. Continued use after a change means you accept the revised terms. See also our privacy policy.
