The math for a 14x12 shed base

  1. Area: 14 × 12 = 168 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 168 × 0.333 = 56.0 cu ft.
  4. Cubic yards: ÷ 27 = 2.07 yd³.
  5. Tons: × 1.55 = 3.2 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. Weight per yard is a planning number; the scale ticket at the yard is the real one.

Preparing the shed base

Level the footprint, extend the stone a foot or so beyond the shed walls for drip and drainage, and compact in lifts. A timber or block border holds the pad shape. Since the shed base carries a shed floor frame, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 3.5 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 shed base as firm ground allows.

When to choose crusher run

Good uses:

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

Poor fit for:

  • 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 4 inches takes about 3.8 tons.
  • Weight used here: about 1.55 tons per cubic yard.

Mistakes that throw off the order

  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
