Terms of Use

Use of the site

You may use the calculators and guides for personal and commercial planning purposes. You agree not to misuse the site — no attempts to disrupt service, scrape at scale, or reverse-engineer for republication of our content as your own.

Estimates, not guarantees

The board foot figures, prices, and shipping weights are estimates for planning. Lumber pricing varies by region, species, grade, and market; weights vary with moisture content. Always confirm final quantities and costs with your supplier before purchasing. Full detail is in our disclaimer.

Intellectual property

The text, charts, calculators, and design on this site are owned by BuildCalcHub and protected by copyright. You may reference and link to our pages, and quote short excerpts with attribution and a link. You may not republish entire pages, charts, or the calculator code without written permission.

Third-party links and ads

We link to external resources and display advertising through Google AdSense. We don't control third-party content and aren't responsible for it. Following an external link or ad is at your own discretion; review that site's own terms and privacy practices.

Limitation of liability

The site is provided "as is" without warranties of any kind. To the fullest extent permitted by law, BuildCalcHub and Nathan Cole are not liable for any loss or damage arising from reliance on the calculators or content, including over- or under-ordering lumber. Your use is at your own risk.

Changes to these terms

We may update these terms; continued use after changes means you accept them. The "last updated" date reflects the current version. See also our privacy policy, and reach us via contact with any questions.
