Bale storing is also more efficient when square bales are used. The square bale stacks have a smaller footprint, are denser, and can be safely stacked higher compared to round bales. The heavier and denser square bales also withstand storing better and can hold up their form better when stacked or piled. Square bale storage has lowered fire risk, as there are much fewer air gaps between the bales. Square bales can be stacked even 10 bales high depending on the local regulations.
