What length can a 2×12 span?
A 2×12 (2-by-12) floor joists can span up to 23 feet 3 inches, 2×10 (2-by-10) up to 19 feet 1 inches, 2×8 (2-by-8) up to 15 feet & 2×6 (2-by-6) up to 11 feet 4 inches at 16″ spaced by using southern yellow pine graded as #1 when live load of 30 lbs/ft^2 & dead load of 10 lbs/ ft^2.
What size lumber will span 16 feet?
For a 16 foot span, you will need atleast 3-2×14 or 6×14 size of wood beam. Thus, a 3 nailed 2×14 or 3-2×14 or 6×14 wood beam can allow to span 16 feet. For a 16-foot spans, the wood beam has to be at least 14 inches in depth and 6″ in width (3-2×14) used for residential building, wood frame structure or projects.
You will see that a 4-ply, 2 X 12 can span a maximum of 13′ while supporting 12′ joists on either side of it. The best place to pick up span tables is at your local lumber yard since they will have all the tables that are used in your region.
What is the maximum span for a 2×10 floor joist?
With 16” spacing, a floor joist can span up to 14’ as long as it is not cantilevered and terminates with support on either end. If the joists are 24” apart, then one 2×10 joist can span up to 11’ 5”. These lengths are for SYP lumber. If you have Spruce-pine-fir lumber, then your span changes to 13’ 7” for 16” joist spacing.
How far can you span a 2×6 floor joist?

How far can a 2×12 LVL span?
It spans long distances. I was able to use LVL for every application in the case-house. Typically, LVL comes 1 ¾” thick and ranges in depth from 7 ¼” up to 18″. To fine-tune the load-carrying potential of a LVL beam, just add another ply to the side of a beam. Labor is a factor. It takes time to laminate multiple layers of LVL. But the upside is that 2 workers can usually handle the weight of each lamination as it is assembled.
