Terms of use

By using MyDeckMath (the "site") you agree to these terms. If you do not agree, please do not use the site.

1. What the site provides

The site offers free calculators and reference information for planning deck construction projects. The tools are provided for general planning and educational purposes only.

2. Not professional advice

Results from our calculators are estimates. They do not constitute engineering, architectural, structural, legal or financial advice. Deck construction is regulated by local building codes, and spans, footings, guards and stairs must comply with the code adopted in your jurisdiction. Always verify calculations with a qualified professional and obtain required permits before building.

3. Accuracy and changes

We work to keep formulas and reference tables accurate, but we make no warranty that any result is complete, current or error-free. Material prices, coverage rates and code tables change over time. We may update, suspend or remove any part of the site at any time without notice.

4. Acceptable use

You may use the calculators for personal and commercial project planning. You may not misuse the site — including attempting to disrupt its operation, scraping it at scale without permission, or misrepresenting our results as professional engineering output.

5. Limitation of liability

To the maximum extent permitted by law, MyDeckMath and its operators are not liable for any indirect, incidental or consequential damages arising from your use of the site or reliance on its results, including costs from material orders, construction errors or project overruns.
