How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Click Calculate to see cubic yards, tons, and cubic feet.

The Home Depot Topsoil Calculator turns your garden dimensions into three practical measurements. You type length and width in feet and depth in inches; the tool first converts depth to feet, multiplies the three numbers to get volume in cubic feet, then divides by 27 to show cubic yards. Because topsoil weighs about 1.3 US tons per cubic yard, the calculator multiplies the yardage by that constant to give an approximate tonnage. Knowing cubic yards helps you order the right bag size, while tons let you compare delivery options. The cubic‑feet figure is handy for comparing against existing soil or estimating fill for small spots. All results appear instantly, so you can plan budget and materials before you step onto the job site.

Pro tips

  • Add 5‑10% extra for compaction and settling.
  • Round up to the nearest half‑yard for easier ordering.
  • Order a little more than calculated to avoid multiple deliveries.
  • Double‑check depth conversion; 12 in = 1 ft.

Real-life examples

  • A homeowner landscaping a 12 × 20 ft patio needs to know how much topsoil to spread 4 in deep.
  • A contractor estimating fill for a new garden bed of 15 × 30 ft at 6 in depth.
  • A DIYer comparing bulk‑delivery cost versus bagged topsoil for a 10 × 10 ft lawn renovation.

Case study

Sarah entered 10 ft × 12 ft × 6 in and the calculator returned 2.22 cubic yards, 2.9 tons and 60 cubic feet. She ordered 3 cubic yards, avoiding a costly second delivery and finished her garden on schedule.

Frequently asked questions

How do I convert depth inches to feet?
Divide the inch value by 12; the calculator does this automatically.
Why is the tonnage only an approximation?
Topsoil density varies, so the 1.3 tons per cubic yard is an industry average.
Do I need to include a waste factor?
Yes, add 5‑10% to the calculated volume to cover settling and spillage.
Can I use the calculator for sand or gravel?
The volume conversion works, but use the specific weight for those materials.
Is the result in US tons or metric tons?
The calculator uses US tons (2,000 lb) as the standard.
