What is the maximum span for a 2×4 floor joist?
He nailed it.
I would just add that as a rule of thumb, maximum span for hem fir joists at 16″ on center is 18 times the nominal joist depth, so for 2×4, multiplying 4 by 18 gives you 72″ maximum span -slightly more than the 5′-9″ but close enough for a rule of thumb..
Can you use 2 2×4 instead of 4×4?
Granted 4x4s when used vertically are still rather strong for most applications, but should never be used horizontally for something structural.

It would probably take over a thousand pounds to break a 2×4 in half on its short length.
What is the load bearing capacity of a 2×4?
A 10 foot long 2×4 carrying a uniform load of 40 pounds per foot (400 lbs total load) will have a maximum bending moment at the center of the span of 1000 ft-lbs. The same 10 foot long 2×4 with a point load of 400 lbs at the center will experience a maximum bending moment of 500 ft-lbs.
How much weight can an inch of wood hold?
Wood bears a toleration of roughly 625 pounds per square inch (PSI) of a compression load. Concrete can bear 3,000 PSI of a compression load.
Which is stronger 2 2×4 or 1 2×6?
According to this website, a double 2×4 is not as strong as a 2×6. Yes, a 2×4 is stroger than a 2×3 as is a 2×6 stronger than a 2×4, but using one over the other does not necessarily make the structure stronger, it just may be overkill. …

3 Answers. The Sagulator says it will support about 375 pounds (evenly distributed) before there is noticeable deflection.

How far can a 2×4 span without support?
Rule of thumb is 2X4 will span 6′ , 2X6 = 8′. Who is? Use 2×8’s or don’t bother building it, as it will sag. With a 20 pound dead load, max span for a 2×4 is 5 feet.
Is a 2×4 stronger on its side?
Thus, we can simply divide these two areas to get the ratio of a 2×4’s stiffness in each orientation. The Ls cancel out, leaving us with just 3.5/1.5 = 2.333. Or in other words, a 2×4 on its side is 2.333 times stiffer than one on edge.
Can you build a deck out of 2×4?
For the deck surface, you can use 2x4s, 2x6s, or 5/4x6s. The 5/4 decking (pronounced “five-quarter”), available in cedar and pressure-treated fir, is 1 inch thick and 5-1/2 inches wide with rounded edges that make for a splinter-free surface.
