The math for a 22x25 driveway

  1. Area: 22 × 25 = 550 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 550 × 0.333 = 183.3 cu ft.
  4. Cubic yards: ÷ 27 = 6.79 yd³.
  5. Tons: × 1.4 = 9.5 tons.

About crushed stone

Most quarries sell crushed stone by a size number or a screen size. Clean crushed stone drains well; stone with fines packs harder but sheds water more slowly. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 10.5 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
  • Bulk vs bags. At this size bulk delivery is usually the practical choice.
  • Where it drops. Have the truck dump as close to the driveway as firm ground allows.

When to choose crushed stone

Good uses:

  • Driveway top courses and parking pads
  • Shed and hot tub bases
  • Backfill behind walls when a clean size is used

Less suited to:

  • Barefoot areas, since angular stone is rough
  • Play areas
  • Places that need a smooth rolling surface for wheels

Quick reference numbers

  • Per inch over 100 sq ft: about 0.43 tons of crushed stone (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.3 tons.
  • Another size for comparison: a 15x30 area at 3 inches takes about 5.8 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Where estimates go wrong

  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
