  2. Enter the width in feet.
  3. Enter the height in feet.
  4. Read cubic feet and cubic yards results instantly.

What it does – This free online tool takes three measurements in feet (length, width, height) and instantly shows you the volume in cubic feet and the equivalent in cubic yards. Knowing the exact volume helps you order the right amount of soil, mulch, gravel, or concrete, preventing costly over‑orders or shortfalls. Why it matters – One cubic yard equals 27 cubic feet, so a small mistake in measurement can translate into dozens of extra feet of material. The calculator does the conversion for you, eliminating manual math errors. How to read the results – The first number is the raw cubic‑feet total. Divide that by 27 (the constant) to get cubic yards, which the tool displays beside it. Use the yard figure when quoting suppliers, as most bulk materials are sold by the cubic yard.

Pro tips

  • Add a 5‑10% waste allowance for compactable material.
  • Round up to the nearest 0.1 cubic yard when ordering.
  • Measure interior dimensions for fill projects, not exterior.
  • Double‑check that all inputs are in feet, not inches.

Real-life examples

  • A homeowner estimating soil needed to fill a garden bed.
  • A contractor calculating concrete volume for a slab.
  • A landscaper planning mulch for a flowerbed.

Case study

Jane needed to fill a 12 ft × 8 ft × 4 ft garden bed. Using the calculator, she saw the volume was 384 cubic feet, which converts to 14.2 cubic yards. She ordered 15 cubic yards of soil, avoiding a shortfall and saving $120 by not over‑ordering.

Frequently asked questions

What is the difference between cubic feet and cubic yards?
Cubic yards are larger; 1 cubic yard equals 27 cubic feet.
Do I need to convert inches to feet before using the calculator?
Yes, all dimensions must be entered in feet; convert any inches to feet first.
Can I use this calculator for irregular shapes?
It works for rectangular prisms; for irregular shapes break them into boxes or use specialized tools.
Why should I add a waste factor?
Materials like soil settle or are lost during handling, so adding 5‑10% ensures you have enough.
Is the result rounded automatically?
The tool shows the exact conversion; you can round the cubic‑yard figure as needed for ordering.
