| 4 in | 11.85 | 18.4 | 20.2 |

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 26x42, or 1,092 sq ft. At 6 inches that is about 31.3 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
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Crusher run mixes stone and stone dust, so it packs nearly solid when compacted in layers. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
