Can you use 2x4 for deck joists?

Will a 2x4 sag?

Why are 2 2x4 stronger than a 4x4?
1) Real world 2 X 4’s have knots in them. With doubled 2 X 4’s, the knots do not line up, so the assembly is stronger. 2) If it’s used as a long column, the maximum load is limited by buckling in the thin direction. The thin direction is twice as thick in doubled 2 X 4’s, so has eight times the resistance to buckling.

What weight can joists support?

Are 2x4 walls load bearing?
If it’s a solid 2×6 or greater turned vertically going from the jack stud on one side to the other, there’s a good chance the wall is load bearing. If there are only cripple studs on a flat 2×4 to give you something to attach the drywall, it likely isn’t load bearing.
