How Much Crushed Stone for a 6x24 Shed Base?

A 6 by 24 foot shed base is 144 square feet. How much crushed stone for a 6x24 shed base depends on depth: at 4 inches it is about 1.78 cubic yards or 2.5 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 6x24 shed base

  1. Area: 6 × 24 = 144 sq ft.
  2. Depth in feet: 4 ÷ 12 = 0.333 ft.
  3. Cubic feet: 144 × 0.333 = 48.0 cu ft.
  4. Cubic yards: ÷ 27 = 1.78 yd³.
  5. Tons: × 1.4 = 2.5 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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

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. 2.7 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 crushed stone

Good uses:

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

Poor fit for:

  • 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.

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.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
