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 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.
A 2x4 stud with the same loading as above but spaced only at 16 inches does not calc. Shorten that stud to 8 feet long and it makes it, but barely. To get a 2x4 to calc at 24-inch spacing, it can be no longer than 9 feet and support only roof load. Most of the trouble with 2x4 studs is their weakness in resisting wind load. But interiors donât experience wind, so using 2x4s at 24-inches there makes sense.
