Terms of Use

Free tools, provided as-is

All calculators and content on Tradesman Math are provided free of charge and "as is," without warranty of any kind, express or implied — including fitness for a particular purpose.

Not engineering advice

Calculator results are estimates based on published formulas, code tables, and typical material properties. They do not constitute professional engineering, architectural, or building-code advice. Building codes, lumber grades, and site conditions vary. Always:

• Verify results against your local building code.
• Consult a licensed engineer or inspector for structural work.
• Confirm material specs with your supplier.

No liability

To the maximum extent permitted by law, Tradesman Math and its operators are not liable for any damages arising from the use of this site, its tools, or reliance on its content — including property damage, personal injury, or financial loss.

Intellectual property

The site's code, text, and design are original works. You may use the tools freely, but do not republish the content wholesale or resell the software.

Changes

These terms may be updated as the site grows. Continued use of the site means you accept the current terms.
