Pole barn pad depth
A 4-inch layer works for storage and light use on firm soil. For equipment, vehicles or a future concrete floor, 6 to 8 inches of compacted stone is common, and soft ground may need more plus fabric underneath.

Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 38x50 feet, 1,900 sq ft, about 49.3 tons at 6 inches. It keeps mud away from the doors and protects the post bases.
Build it in layers
Remove sod and organic soil first. Compact the subgrade, then place and compact the stone in thin lifts. If the barn floor will be stone permanently, finish with a material that has fines so it packs firm.
Ordering and delivery
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. Round up by about 10 percent for compaction and uneven ground.
