Tips & Notes

  • ✓Topsoil weighs approximately 2,000-2,200 lbs per cubic yard.
  • ✓For raised beds, standard depth is 6-12 inches.
  • ✓Order 5-10% extra to account for settling after watering.

Common Mistakes

  • ✗Not converting depth from inches to feet before calculating.
  • ✗Underestimating settling — soil compacts 10-20% after watering and natural settling.
  • ✗Confusing cubic yards with cubic feet — 1 cubic yard = 27 cubic feet.

Soil Calculator Overview

Soil Calculator Overview

The Soil Calculator determines how much soil you need for garden beds, lawns, raised planters, and fill projects by converting area dimensions and depth into cubic yards. It also estimates weight in tons and total cost based on local pricing — essential for planning delivery logistics and project budgets.

Soil depth requirements vary by application: new lawns need 4-6 inches of topsoil, garden beds benefit from 6-12 inches, and raised beds typically require the full depth to be filled. Using the right depth ensures healthy plant growth while avoiding unnecessary material costs.

Remember that soil settles over time. The 10-20% settling that occurs in the first season means your initial application should slightly exceed the target depth to maintain the desired level after compaction.

Frequently Asked Questions

Topsoil typically weighs 1,800-2,200 pounds (0.9-1.1 tons) per cubic yard depending on moisture content. Wet soil is significantly heavier than dry soil. Sandy soil is lighter, while clay soil is heavier.

For new lawn establishment, apply 4-6 inches of topsoil. For overseeding existing lawns, 1-2 inches is sufficient. For garden beds, 6-12 inches provides adequate growing depth for most plants.

Topsoil is the upper layer of natural soil, rich in organic matter. Garden soil is a manufactured blend of topsoil, compost, and amendments designed specifically for planting. Garden soil is typically more expensive but better for intensive growing.

Yes. Soil settles 10-20% over the first few months as it compacts from watering and gravity. Order slightly more than calculated to maintain your desired depth after settling.
