  2. Enter width in feet
  3. Enter height in feet
  4. Click Calculate to see cubic yards

What it does – The Cubic Yardage Calculator converts a space measured in feet (length × width × height) to cubic yards, the unit most suppliers use.

Why it matters – Knowing the exact cubic yards prevents over‑ordering concrete, mulch, or fill, saving money and avoiding project delays.

How to read the result – The tool divides the total cubic feet by 27 (the exact conversion factor) and shows the answer rounded to two decimals. Enter your dimensions, click Calculate, and you’ll see the volume ready to quote to contractors or suppliers.

Pro tips

  • Add 5‑10% extra for compaction or spillage.
  • Round up to the nearest 0.1 yd³ for ordering.
  • Measure interior dimensions for enclosed jobs, exterior for fill.
  • Double‑check that all inputs are in feet; inches must be converted first.

Real-life examples

  • A homeowner ordering a concrete slab for a new patio.
  • A landscaper calculating mulch needed for a garden bed.
  • A contractor estimating fill material for a basement excavation.

Case study

Mike needed 2 × 3 × 4 ft of concrete for a garage floor. Using the calculator, he saw the volume was 0.89 yd³, ordered exactly that amount, and saved $150 by avoiding excess material.

Frequently asked questions

Why is my result a decimal?
Cubic yards rarely divide evenly; the calculator shows two decimal places for precision.
Do I need to include the thickness of a slab?
Yes, height is the slab thickness; include it to get the correct volume.
Is the calculator free?
