Extending the pad past the walls
Many owners run the stone 1 foot beyond each wall: 26x26 feet, 676 sq ft, about 18.8 tons at 6 inches. It keeps mud away from the doors and protects the post bases.
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.
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. Road base is a graded stone-and-fines mix built to compact into a load-bearing layer. Round up by about 10 percent for compaction and uneven ground.
