Contact YardCalc

Found a formula that looks off, or a calculator you wish existed? We want to hear it — corrections get priority.

Email support@yard-calc.site and include the page URL you're writing about.

What we can help with

• Corrections — a formula, yield, or density figure that's wrong.
• Requests — a calculator you'd find useful.
• Publishers & advertisers — partnership and advertising questions.

What we can't help with

We can't give project-specific engineering, structural, or code-compliance advice. For those questions, a licensed contractor, engineer, or your local building authority is the right resource.
