**41′**. That same truss can span 46′ when built for areas with a snow load of 40 psf.## How much weight can a 2×4 hold flat?

In general, a 2×4 can hold a horizontal load of around

**20 to 40 pounds per linear foot**if the weight is evenly distributed. If the weight is centered between the span, that number could drop to 20 pounds total or less for longer 2x4s. Other factors can increase the weight that a 2×4 can support as well.## Should you use 2×4 or 2×6 for shed floor?
