Until then, we framed headers for window and door openings like most framers in our area—a double 2x12 with a 1/2-inch plywood spacer for a 2x4 wall. With the header installed directly below the double 2x4 top plate on an 8-foot-high wall, the bottom of the header put the finished window head jamb at about 6 feet 10 inches off the finished floor.A double 2×12 beam can span 12 feet; a (2) 2×10 can span 10 feet and so on. How far can a double 2×6 beam span:- as per general rules and guidelines, #2 grade southern pine of a double 2×6 deck beam can span upto 6 feet when total load of 50 psf (40 psf live load + 10 psf dead load) with deflection limit L/360.

So an 8-foot tall wall weighs 8 ft x 16 pounds/ft 2 = 128 pounds per lineal foot. The loads delivered to the header are: Conditions: live load (snow): 50 psf x 14ft = 700 pounds per lineal foot. roof dead load: 15 psf x 14ft = 210 pounds per lineal foot. upper level wall: = 128 pounds per lineal foot.A very rough, napkin-scribble estimation goes something like this: most span tables say doubled 2x12's are good for 12' openings. You have 18', which is 50% wider. Thus, the header will need to be 1.5x1.5=2.25 stronger than the one for a 12' opening.Seems to me you're trying to talk yourself into a full span of twenty feet or more. An 8x8 (even with no load) would sag under its own weight at that distance. Stop agonizing over it and add a mid-span post. Any professional carpenter will tell you the same thing. From contributor A: A 6 x 8 will span 12' for flooring.19-Sept-2023 ... Tell us the size of the span, and what it is made from, and we may be able to get you an estimate.
