Last updated: September 2026

1. Estimates only

2. No professional or engineering advice

Nothing on this site is professional engineering, architectural, surveying, or construction advice, and using it does not create a professional relationship of any kind. The calculators do not determine and must not be relied on for:

• structural design, or beam, post, joist, or footing sizing;
• structural spans, load capacity, or deflection;
• ledger attachment, fastener schedules, or structural connections;
• guardrail, stair, or barrier requirements;
• permit requirements or building code compliance.

For any of the above, consult a licensed contractor, structural engineer, or your local building department.

3. No guarantee of accuracy

The site is provided "as is" and "as available", without warranties of any kind, express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. While the calculators are tested and their formulas are published on the pages themselves, no guarantee is made that any result is accurate, complete, current, or suitable for your project.

4. Your responsibilities

Before you buy materials or begin work, it is your responsibility to:

• verify all measurements yourself, on site;
• confirm actual product dimensions, since board widths and lengths vary by supplier, material, and manufacturer;
• follow the decking and fastener manufacturers' installation instructions, including spacing, fastening, and joint support requirements;
• verify structural design and framing with a qualified professional;
• confirm permit and building code requirements with your local building department.

You are solely responsible for decisions made and materials purchased based on results from this site.

5. Limitation of liability

To the fullest extent permitted by law, DeckBoardEstimator.com and anyone associated with operating it accept no liability for any loss, cost, delay, injury, or damage — direct, indirect, incidental, consequential, or otherwise — arising from use of this site or reliance on any result it produces. This includes over-ordering or under-ordering materials, wasted materials, project delays, rework, and any construction defect.

6. Website availability

The site is offered free of charge and may be changed, interrupted, or discontinued at any time without notice. No guarantee is made that it will be available, uninterrupted, or error-free, and calculators or pages may be modified, corrected, or removed as they are improved.

7. Intellectual property

The content, design, layout, text, and code of this site are owned by the site operator and protected by applicable intellectual property law. You may use the calculators and reference the content for your own personal or professional project planning. You may not copy, republish, scrape in bulk, or redistribute substantial parts of the site, or present it as your own, without permission. Brand names and trademarks mentioned in the content belong to their respective owners and are used only for identification.

8. Acceptable use

Do not use the site in any way that is unlawful, or that damages, disables, overburdens, or impairs it or interferes with anyone else's use of it.

9. External links

Some pages link to third-party websites. Those are provided for convenience only, and the site operator does not control and is not responsible for their content, accuracy, or practices.

10. Changes to these terms

These terms may be updated at any time. The "last updated" date above will change when they are, and continued use of the site after a change means you accept the revised terms.
