How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, tons, and cubic feet results.
What it does – The calculator converts the length, width and depth of a soil area into three useful measures: cubic yards, cubic feet, and an approximate tonnage (1 cubic yard ≈ 1.3 US tons). Why it matters – Knowing cubic yards lets you order the correct amount of topsoil, mulch or fill, avoiding costly over‑orders or shortfalls. How to read – The cubic yards number is what suppliers quote. Multiply by 1.3 to see the ton estimate shown for you. Cubic feet is handy for smaller projects or when your supplier lists volume in feet. The tool updates instantly as you change any input, so you can experiment with different depths before you commit. You can also save the result for a quick quote or share it with a contractor. Because the calculation is based on exact geometry, the figures stay reliable even for irregularly shaped beds when you break them into rectangles.
Pro tips
- Add 5‑10% extra volume to cover settling and compaction.
- Round up to the nearest 0.1 cubic yard for ordering simplicity.
- Check supplier pricing per ton vs per cubic yard to choose the cheaper unit.
- Double‑check depth conversion; 12 in equals 1 ft, so 6 in is 0.5 ft.
Real-life examples
- A homeowner planning a new garden bed needs to know how much topsoil to buy.
- A landscaper estimating fill material for a patio ramp wants cubic yards and tonnage.
- A DIY enthusiast ordering mulch for a backyard path wants to avoid ordering too much.
Case study
Maria wanted to fill a 12 ft × 8 ft garden to a 6‑inch depth. Using the calculator she saw she needed 1.33 cubic yards (≈ 1.7 tons). She ordered exactly that amount, saved $45 on excess soil, and completed the bed on schedule.
