How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Read cubic yards, tons, and cubic feet results.

What it does – The calculator turns the dimensions of your planting bed or lawn into three practical quantities: cubic yards (the unit suppliers use), tons (weight for delivery), and cubic feet (useful for on‑site planning). Why it matters – Ordering too little means a patchy finish; ordering too much wastes money and space. How to read the results – Cubic yards is the volume you’ll quote to a vendor; multiply by 1.3 to see the approximate tons you’ll be charged; cubic feet helps you visualize the depth across the whole area. For example, a 20 ft × 15 ft area 6 in deep yields 5.56 yd³, about 7.23 tons, or 150 ft³. You can also use the tool for larger projects such as filling a new patio, leveling a backyard, or preparing a sports field. Simply plug in the numbers, and the calculator instantly provides the three measurements, so you can compare quotes, plan delivery logistics, and avoid costly guesswork. No need for spreadsheets or manual conversions.

Pro tips

  • Add 5‑10% extra volume to cover settling.
  • Round up to the nearest half‑yard when ordering.
  • Verify your supplier’s ton‑per‑cubic‑yard rate; 1.3 tons/yd³ is typical.
  • Measure depth in inches, not feet, to avoid under‑estimation.

Real-life examples

  • A homeowner planning a 10 ft × 12 ft flower bed 4 in deep needs exact topsoil volume before ordering.
  • A landscaper preparing a 30 ft × 40 ft lawn renovation 8 in deep wants to quote the client in tons and yards.
  • A DIYer filling a 15 ft × 20 ft patio area 5 in deep wants to know how much soil to schedule for delivery.

Case study

Sarah needed to fill a 15 ft × 20 ft patio area 5 in deep. Using the calculator she saw she required 5.56 yd³ (≈7.2 tons). She ordered exactly that amount, saved $120 on excess soil, and completed the project on schedule.

Frequently asked questions

How do I convert cubic yards to tons?
Multiply the cubic yards by 1.3 US tons per cubic yard.
My depth is in centimeters—what do I do?
Convert centimeters to inches (1 in = 2.54 cm) before entering the depth.
Should I account for soil compaction?
Add a 5‑10% waste allowance to the calculated volume to cover compaction and settling.
Can I use this for ordering mulch?
No, mulch has a different density; use a mulch‑specific calculator.
Is the calculator accurate for sloped areas?
Measure the horizontal length and width, or break the slope into smaller rectangles and average the results for best accuracy.
