How Much Crusher Run for a 20x150 Driveway?

A 20 by 150 foot driveway is 3,000 square feet. How much crusher run for a 20x150 driveway depends on depth: at 4 inches it is about 37.04 cubic yards or 57.4 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 20x150 driveway

  1. Area: 20 × 150 = 3,000 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 3,000 × 0.333 = 1,000.0 cu ft.
  4. Cubic yards: ÷ 27 = 37.04 yd³.
  5. Tons: × 1.55 = 57.4 tons.

About crusher run

The fines in crusher run fill the gaps between stones, so it weighs more per yard than clean stone once compacted. Plan on rolling or plate-compacting it in lifts. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

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. 63.1 tons may take more than one 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 crusher run

Best suited to:

  • Base under asphalt, pavers or concrete
  • Gravel drives that need a firm, packed surface
  • Shed pads and equipment pads

Less suited to:

  • Drainage layers, since the fines slow water
  • Decorative beds
  • Spots where you want water to soak straight through

Quick reference numbers

  • Per inch over 100 sq ft: about 0.48 tons of crusher run (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.8 tons.
  • Another size for comparison: a 10x20 area at 3 inches takes about 2.9 tons.
  • Weight used here: about 1.55 tons per cubic yard.

Common estimating mistakes

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
