How to use it

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

This tool converts the dimensions of your planting area into the three most useful measurements for ordering topsoil: cubic yards, cubic feet, and an estimated weight in tons. Knowing the cubic yards tells you how many bulk bags or truckloads to order; cubic feet helps when you’re buying from a local supplier that sells by the foot. The ton estimate uses the industry standard 1.3 US tons per cubic yard, giving you a quick sense of material cost and truck capacity. Simply input length, width, and depth, hit Calculate, and the results appear instantly. Use the numbers to compare quotes, avoid over‑ordering, and keep your landscaping budget on track. The cubic‑yard figure is the primary ordering metric; the cubic‑foot value is useful for smaller projects, and the ton figure helps when freight charges are weight‑based.

Pro tips

  • Add 10% extra for compaction and settling.
  • Round up to the nearest whole cubic yard for bulk orders.
  • Order by weight (tons) when freight is priced per ton.
  • Double‑check depth; a small change dramatically affects volume.

Real-life examples

  • A homeowner landscaping a new flower bed wants to know how much topsoil to order.
  • A contractor preparing a lawn renovation needs accurate tonnage for delivery quotes.
  • A garden center customer comparing bulk‑bag versus truck‑load options.

Case study

Maria entered her 20 ft × 15 ft patio area with a 4‑inch depth, got 3.7 cubic yards (≈4.8 tons) and ordered exactly that amount, avoiding a costly extra load and finishing her project on schedule.

Frequently asked questions

How do I convert the calculator result to bags of topsoil?
Divide the cubic yards by the bag’s volume (usually 0.5 cubic yards) and round up.
Why does the ton estimate differ from the cubic‑yard number?
Because each cubic yard of topsoil weighs about 1.3 US tons, the calculator multiplies by that constant.
Can I use this for sand or mulch?
The volume conversion works for any loose material; just use the appropriate weight per cubic yard if you need tons.
What if my area isn’t a perfect rectangle?
Break the space into rectangles, calculate each separately, then add the results.
Do I need to account for soil compaction?
Add a 5‑10% waste allowance to the final volume to cover settling and compaction.
