How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, tons, and cubic feet results.
The Topsoil How Much Calculator turns the three dimensions of your planting area into the exact amount of soil you’ll have to order. You input length, width, and depth; the tool instantly shows cubic feet, converts that to cubic yards (the unit suppliers use), and then estimates weight using the industry standard 1.3 US tons per cubic yard. Knowing these numbers helps you avoid costly over‑orders or running short mid‑project. The cubic‑yard figure tells you how many loads to request from a local supplier, while the ton estimate lets you compare pricing per weight. The cubic‑foot result is useful for smaller DIY jobs or when checking against bagged soil totals. Because the calculator uses the exact conversion of 27 cubic feet per cubic yard and the fixed 1.3‑ton density, the results are reliable for any residential project.
Pro tips
- Add 5‑10% extra for compaction and settling.
- Round up to the nearest half‑yard for ordering convenience.
- Compare supplier quotes by both cubic yards and tons.
- Double‑check depth measurement; a common mistake is using feet instead of inches.
Real-life examples
- A homeowner preparing a new flower bed 12 ft × 8 ft × 4 in.
- A landscaper estimating soil for a 30 ft × 20 ft lawn renovation at 6 in depth.
- A DIY gardener buying bagged topsoil for a raised‑bed garden 6 ft × 6 ft × 8 in.
Case study
Maria needed soil for a 15 ft × 10 ft patio garden 5 in deep. Using the calculator she saw she required 2.3 cubic yards (≈3 tons). She ordered 2.5 cubic yards, saved $45 on excess material, and completed the project on schedule.
