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
Adding 1 foot on every side makes the pad 26x42, or 1,092 sq ft. At 6 inches that is about 28.3 tons. A wider apron sheds water away from the posts and gives the eave drip a place to land.
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. 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.
