Understanding Your Results
Cubic Yards: The standard measurement for bulk material orders. One cubic yard covers 324 square feet at 1-inch depth.
Tons: Weight measurement for delivery. Conversion varies by material - topsoil averages 1.3 tons per cubic yard.
Bags: For smaller projects. Standard bags are 2 cubic feet for mulch/soil, 40 pounds for compost.
Frequently Asked Questions About Free Online Soil Calculator (FAQ)
How much soil do I need for a 4x8 raised bed?
For a standard 4x8 foot raised bed with 12-inch depth, you'll need approximately 1.2 cubic yards or 32 cubic feet of soil. This equals about 16 bags of 2 cubic feet bagged soil.
How many cubic yards are in a ton of topsoil?
One cubic yard of dry topsoil weighs approximately 1.3 tons. Wet or compacted soil can weigh 1.5-1.7 tons per cubic yard. For accurate ordering, use our calculator's material-specific conversions.
How deep should mulch be?
Apply 2-3 inches for decorative mulch and weed suppression, 3-4 inches for slopes or heavy weed prevention. Avoid piling mulch against tree trunks or plant stems to prevent rot.
Should I buy bulk or bagged soil?
For projects over 2 cubic yards, bulk delivery is typically more cost-effective. Bagged soil offers convenience for smaller projects and easier handling. Use our cost calculator to compare options.
How do I calculate soil for irregular shaped areas?
Break irregular areas into simple shapes (rectangles, triangles, circles). Calculate each section separately, then add the totals. Our calculator supports multiple shape types for accurate measurements.
What's the best soil mix for raised beds?
A basic mix of 60% topsoil and 40% compost works well. For premium results, use 1/3 topsoil, 1/3 compost, and 1/3 peat moss or coconut coir. Our calculator provides recipes for different mix ratios.
How much does delivery typically cost?
Bulk material delivery usually ranges from $50-150 depending on distance and quantity. Many suppliers offer free delivery for orders over 5 cubic yards. Factor delivery into your cost comparison.
Can I use this calculator for gravel and sand?
Yes! Select gravel or sand as your material type. The calculator adjusts weight calculations accordingly - gravel weighs approximately 1.5 tons per cubic yard, sand about 1.3 tons.
