**If you assume a conservative 1400psi allowable bending stress, a single 6×6 with 12′ span can support about 2000 lbs.**

## How Much Weight Can a 6×6 Support Horizontally?

When it comes to construction, understanding the structural capabilities of various materials is essential. This is particularly true when considering how much weight a 6×6 support beam can handle horizontally. Though the exact weight capacity depends on several factors, there are several general considerations. Below, you will find an overview of what you need to know when considering how much weight a 6×6 support beam can support horizontally.

First, it is important to note that the strength of a 6×6 support beam will depend on the type of wood it is made from. For example, Douglas fir is generally much stronger than pine. As such, the weight capacity of a 6×6 beam will depend largely on the type of wood used.

Second, when considering the weight capacity of a 6×6 support beam, the length of the beam should be taken into account. Generally speaking, longer beams can handle more weight than shorter ones. This is because longer beams have a greater surface area, which gives them increased strength.

Third, the weight capacity of a 6×6 support beam will also be determined by the number of supports it has. The more supports a beam has, the more weight it can support. This is because additional supports provide greater stability and distribute the weight
