The math

  1. Area: 1,200.0 sq ft.
  2. Depth in feet: 6 ÷ 12 = 0.500 ft.
  3. Cubic yards: 1,200.0 × 0.500 ÷ 27 = 22.22 yd³.
  4. Tons: × about 1.55 tons per yard = 34.4 tons.

The crushed stone calculator does this for any size.

Pole barn pad depth

Plan the pad around what the barn will hold. Hay and tools sit fine on 4 inches of compacted stone; tractors, trucks or a later slab pour justify 6 to 8 inches built up in compacted lifts.

Extending the pad past the walls

Many owners run the stone 1 foot beyond each wall: 32x42 feet, 1,344 sq ft, about 38.6 tons at 6 inches. It keeps mud away from the doors and protects the post bases.

Layering the base

Strip topsoil, level and compact the subgrade, then spread stone in lifts of about 3 to 4 inches, compacting each. A coarser base topped with a finer, packable stone often makes the most solid floor.

Getting it delivered

Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. The scale ticket is the real weight; tons per yard here is a planning figure.
