Gravel Calculator

Different gravel and crushed stone products compact to different weights per volume — most crushed stone and gravel mixes fall in the 1.3-1.5 tons per cubic yard range, so the default of 1.4 is a reasonable middle estimate, but ask your supplier for the specific product's density for the most accurate tonnage figure.

A typical gravel driveway uses 4-6 inches of base material (sometimes with an additional compacted sub-base beneath), while a garden path might use only 2-3 inches — check local guidance for vehicle-load driveways, since a path and a driveway have very different depth requirements.

Most gravel and aggregate suppliers price and deliver material by the ton, not by the cubic yard, so the tons-needed figure is usually the number you'll actually use when placing an order — the cubic yard and cubic foot figures are shown mainly as intermediate reference numbers.

Many contractors add 5-10% extra to account for compaction settling and uneven ground that requires slightly more material than a flat-area calculation assumes — this calculator gives the base theoretical volume, so consider rounding your order up a bit for a real-world project.
