Cubic Yards Calculator
Cubic Yards Calculator
Enter length, width, and depth in feet to find the volume in cubic yards — the standard unit most bulk materials (dirt, gravel, mulch, sand, concrete) are bought and delivered in.
Suppliers price and deliver almost all bulk landscaping and construction materials by the cubic yard rather than cubic feet, which is why converting your project's raw dimensions into that unit is the first real step in getting an accurate delivery quote — dividing the raw cubic-foot volume by 27 makes that conversion. Because this calculator works purely on volume, it applies identically whether you're ordering dirt for a garden bed, gravel for a driveway base, or sand for a playground — only the material's price and weight-per-yard differ, not the underlying volume math.
- Imperial formula: Cubic Yards = (Length × Width × Depth in feet) ÷ 27. Example: 20×10 ft at 1 ft deep = 7.41 cubic yards.
- Metric formula: Cubic Meters = Length × Width × Depth, all in meters. Example: 6×3 m at 0.3 m deep = 5.4 cubic meters.
- Works for any bulk material — dirt, gravel, mulch, sand, or concrete — in either unit system.
My depth is in inches, not feet — what do I do?
Divide the inches by 12 first to convert to feet (e.g. 4 inches = 0.33 ft), or use one of the material-specific calculators on this site, which accept depth directly in inches.
Why do suppliers sell by the cubic yard?
It's the standard bulk delivery unit in the US for materials like soil, gravel, and mulch — a dump truck load is typically quoted and billed in cubic yards.
