How far can a double 2×8 floor joist span?

2 Answers. No, you cannot span 23 feet with conventional lumber, even doubled. It’ll be as bouncy as a trampoline and won’t meet code, and that’s if you can find such lengths. You’ll need at least a 12″ (nominal) I-joist or an engineered floor truss to span that far, or you’ll need an LVL or steel beam midway.

Is a 4×6 stronger than 2 2×6?

A 4×6 joist is theoretically stronger than a doubled 2×6 joist because it’s 1/2″ thicker, but the actual strength depends upon the knots and other inherent weaknesses of any particular piece of lumber (#2 lumber can have some nasty spike knots or large not-so-tight round knots or wane).
