Bearing span
WebThe size of the lumber used for floor joists is the single greatest determining factor in terms of how far a joist can span. The joist span tables start with 2×6 lumber and it goes all the way up to 2×12. For example, a 2×6 Southern Pine joist can span 12’. A 2×12 joist of the same species and quality can span nearly 25’. WebA doubled 2×4 can support a span of 3’ 6” if the only structure above the beam or header is the ceiling and roof for a 20’ wide home. If there is a floor on top, then the same beam or header can span 3’ 1” if there is a load-bearing wall in the center of the structure, and a 2’ 8” if there is no center bearing wall.
