About Us
Free landscaping calculators built around clear formulas, practical assumptions, and real project decisions.
Last updated September 11, 2026Practical Numbers for Real Yard Projects
My Yard Calculator provides free tools for estimating gravel, mulch, stone, soil, topsoil, dirt, grass seed, plant spacing, landscape rock, and retaining wall materials. The site is designed for homeowners, gardeners, landscapers, and anyone who needs a clear starting quantity before requesting a supplier quote.
Our goal is simple. Each calculator should answer the purchasing question behind the measurements and show enough information for the user to understand the result.
What We Provide
- Project specific calculators instead of one general answer
- US customary and metric inputs where practical
- Volume, weight, bag, coverage, block, seed, and cost estimates
- Visible formulas, examples, assumptions, and rounding notes
Who the Tools Help
- Homeowners planning lawn and garden work
- DIY users comparing bulk and bagged materials
- Landscape professionals checking early quantities
- Students learning area, volume, density, and unit conversion
How We Build Trust
Every calculator is tested with known examples and boundary cases. Formulas use standard geometry and unit conversions. Material density remains an estimate because moisture, grading, compaction, product blend, and supplier methods can change real weight.
We explain those limits on the calculator page and recommend confirming final quantities, product coverage, delivery limits, and pricing with the supplier. Retaining wall results estimate materials only and do not replace engineering, manufacturer instructions, permits, or local code review.
Corrections and Updates
Clear corrections are part of responsible publishing. If a formula, link, assumption, or explanation needs attention, users will be able to report it through our Contact page. Calculator logic and supporting information will be reviewed as the site grows.
