The math for a 14x8 shed base

  1. Area: 14 × 8 = 112 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 112 × 0.333 = 37.3 cu ft.
  4. Cubic yards: ÷ 27 = 1.38 yd³.
  5. Tons: × 1.55 = 2.1 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. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

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. For a shed floor frame, the depths in the table above are a reasonable starting range.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 2.4 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.

Good and poor uses for crusher run

Good uses:

  • 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 12x24 area at 3 inches takes about 4.1 tons.
  • Weight used here: about 1.55 tons per cubic yard.

Mistakes that throw off the order

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
  • 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.
