TL;DR
Floor decking thickness is the panel depth chosen for a shed's floor surface, matched to joist spacing and expected loads: 3/4-inch tongue-and-groove plywood or OSB over joists at 16 inches on center handles mowers and shelving, while 12-inch spacing or doubled panels serve tractors and heavy machines. Thinner 5/8-inch sheet floors flex and pop fasteners under point loads.

Thinner 5/8-inch sheet floors flex and pop fasteners under point loads. Pressure-treated plywood is standard near grade, since untreated decking wicks ground moisture and delaminates from beneath.
