Double 2x12 floor joist.
 
Currently my floor-plan is 20 ft wide my second story is 2x12x20 12" O.C southern pine grade 2. I would like to stretch the building to 25' Can i double up 2 2x12x20's on 16" O.C. for my floor joist.

Cost is the factor here the I beams for 25' local are 143 and floor trusses are 164. 2 2x12x26's are 43 bucks huge cost savings

douglas fir larch 2x12 will span 24' 8" on 12" centers 40psf live 10psf dead so with a overall width of 25' seeing that my joist sit on top of my header my span between walls is 24'1" im good to go.
