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: 42x62 feet, 2,604 sq ft, about 67.5 tons at 6 inches. It keeps mud away from the doors and protects the post bases.
Layering the base
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
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. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. The scale ticket is the real weight; tons per yard here is a planning figure.
