What these quick estimates do—and do not do
Each calculator enumerates feasible axis-aligned rows across the load width, allowing a 90-degree rotation, and multiplies the best floor count by complete height layers. Pallet and drum pages lead with unstacked floor positions; a larger stacked count is shown only as a conditional dimensional ceiling.
The estimate does not validate payload or axle limits, door clearance, intrusions, stability, weight distribution, securement, or handling space. Use it for a fast first answer, then run the real cargo through a 3D loading plan before execution.
