Includes your waste allowance. Bulk delivery is usually cheaper than bags beyond ~1 ton. One cubic yard covers about 108 sq ft at 3″ deep.

✅ Project checklist

  • Measure the area twice; mark it out with stakes and string
  • Excavate to depth plus fabric thickness; level and tamp the base
  • Lay landscape fabric with 6″ overlaps; pin the edges
  • Install edging before the gravel goes down
  • Order bulk delivery for the morning of the project; have a wheelbarrow, rake and shovel ready
  • Spread in two passes, rake level, spray lightly to settle dust

How the math works

Volume = area × depth. A rectangle is length × width; a circle is π × (diameter ÷ 2)². Cubic yards = cubic feet ÷ 27. Tons = cubic yards × the material's density (crushed gravel ≈ 1.35 tons per cubic yard). The waste allowance is added last, so the order quantity reflects what you should actually buy, not the perfect-world volume.

For estimation only. Densities vary by material and moisture — confirm the per-ton yield with your supplier before ordering.
