How deep the barn pad should be
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 16.9 tons. A wider apron sheds water away from the posts and gives the eave drip a place to land.
Build it in layers
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.
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. #57 is a washed stone of roughly 1/2 to 1 inch with few fines; it drains fast but stays a little loose on its own. The scale ticket is the real weight; tons per yard here is a planning figure.
