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 26x26, or 676 sq ft. At 6 inches that is about 17.5 tons. A wider apron sheds water away from the posts and gives the eave drip a place to land.
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.
Buying the stone
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. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
