Terms of Service
Last Updated: September 17, 2026. Please read these terms carefully before utilizing our landscaping and construction estimation calculators.
Contractor Estimation Disclaimer
YardCoverageCalc.com provides mathematical estimations for planning purposes only. Subgrade irregularities, settling, compaction, moisture variations, and quarry density differences will impact real-world volumes. Always add a 10% safety buffer and confirm with your bulk materials supplier.
1 Acceptance of Terms
By accessing or using YardCoverageCalc.com, you agree to be bound by these Terms of Service and all applicable laws and regulations. If you do not agree with any part of these terms, you are prohibited from using this website or its calculation tools.
2 Nature of Calculators and Calculation Limits
All tools hosted on YardCoverageCalc.com—including the Mulch, Topsoil, Gravel, Sand, and Cubic Yards calculators—rely upon standard geometric formulas:
- Volume Formula: Rectangular volume is computed via
(Length ft × Width ft × (Depth in ÷ 12)) ÷ 27. - Material Weight Approximations: Bulk material weights (such as 2,300 lbs/yd³ for topsoil, 2,800 lbs/yd³ for gravel, and 4,050 lbs/yd³ for concrete) represent typical industry benchmarks. Moisture content, aggregate gradation, and organic compaction can cause variances of 15% to 25% or more.
- Not Structural Engineering Advice: Calculations are not certified structural, geotechnical, or civil engineering plans. For foundation footings, commercial retaining walls, and civil concrete slabs, consult a licensed structural engineer.
