Also know, how far can a double 2×6 span without support?
When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2×12 beam can span 12 feet; a (2) 2×10 can span 10 feet and so on.
Also, how far can a floor joist span without support? Joist Spans A live load of 60 pounds per square foot demands more support and shorter spans. Spaced at 12 inches, the joist may only span 16 feet 8 inches. At 16 inch spacing, 15 feet 2 inches and 13 feet 3 inches at 24 inch spacing.
Considering this, how much weight can 2×6 floor joists hold?
To give you a general idea though, floor joists are sized to support 40 pounds per square foot of “live” load (moving weight) or 10 psf “dead” (stationary) load.
Does double joists increase span?
The width is considerably more important than the thickness of a board. For example, a joist made from doubled 2 x 6s can span a distance about 25 percent more than a single 2 x 6, but a 2 x 12 can span about 80 percent more than a 2 x 6, even though it has the same amount of wood as a doubled 2 x 6.

How are level beam sizes calculated?
- Measure your total span between members and ensure that it is not greater than 60 feet.
- Design a beam width based on the fact that the typical width of an LVL beam is 1 3/4 inches.
- Design a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20.
