Terms of Service

By using this site you agree to these terms.

Calculators are for planning and education only. Results are estimates, not financial, legal, or construction advice, and not a quote.

You are responsible for checking measurements, material, density, price, delivery, and local rules before ordering or building.

We are not liable for ordering errors, price changes, or project outcomes.

Content may not be copied in bulk or presented as your own. You may link to a calculator page and share a result link.

Terms may be updated here.
