How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, tons, and cubic feet results.
This free Gravel Calculator turns three simple measurements—length, width, and depth—into the three numbers you actually order: cubic yards, tons, and cubic feet. Knowing the cubic yards tells you how many bulk loads to request; the ton estimate helps you compare material costs across suppliers; and the cubic‑foot figure is useful for small‑scale projects or when a supplier quotes by volume. For example, a 10 ft × 10 ft area at 6 in depth equals 50 ft³, which is 1.85 cubic yards and about 2.6 tons (1.4 tons per cubic yard). Use the results to order the right amount without costly over‑ordering or running short mid‑project.
Pro tips
- Add a 10% waste allowance for compaction and spillage.
- Round up to the nearest whole cubic yard for bulk orders.
- Order a little extra to cover future repairs or settling.
- Double‑check depth conversion: 12 in = 1 ft.

Case study
Sam entered his 12 ft × 8 ft patio dimensions and a 4 in depth; the calculator showed 1.19 cubic yards (≈1.7 tons). He ordered 2 cubic yards, avoided a shortfall, and finished on schedule.
