Pole barn pad depth
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
Adding 1 foot on every side makes the pad 26x38, or 988 sq ft. At 6 inches that is about 25.6 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.
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. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. Round up by about 10 percent for compaction and uneven ground.
