A 4x4 piece of lumber can typically span about 6 to 8 feet when used as a vertical post in construction, depending on the load it needs to support and the type of wood. However, if used horizontally as a beam, the span is generally limited to around 4 to 6 feet without additional support. It's crucial to consult local building codes and consider factors like the wood species and the load to ensure safety and structural integrity.
