Informational estimates
YardProjectCalc provides general planning calculations. Results are estimates based on the values you enter and stated assumptions. They are not quotes, guarantees, or professional engineering, architectural, legal, financial, contractor, agronomic, or safety advice.
Your responsibility
You are responsible for checking measurements, product labels, supplier requirements, project conditions, applicable codes, permits, and professional guidance. Do not rely on this site for structural design, load limits, hazardous work, or other safety-critical decisions.
Availability and accuracy
We work to make formulas clear and useful, but cannot promise uninterrupted availability or error-free results. Products, package yields, coverage, density, site conditions, and purchasing increments vary.
Acceptable use
You may use the calculators for lawful personal and business planning. Do not attempt to disrupt the site, bypass security, introduce malicious code, or misrepresent the site or its content as your own service.
Changes
These terms may change as the service develops. The effective date on this page will identify the current version.
