The service

StructMath provides free planning calculators. Results are estimates for planning purposes only — they are not engineering, architectural, or code-compliance advice, and they do not replace professional judgment.

No warranty

The calculators are provided "as is" without warranty of any kind. You are responsible for verifying quantities with your supplier and complying with local building codes before purchasing or building.

Limitation of liability

To the maximum extent permitted by law, the site owner is not liable for losses arising from use of the calculators, including over- or under-ordering of materials or construction outcomes.

Intellectual property

Site content is © the site owner. You may use calculator results freely for your own projects.
