When supporting joists that

**span**12 feet with no overhang beyond the beam, a double ply beam**can span**in feet a value equal to its depth in inches. A double**2x12**beam**can span**12 feet; a (2) 2x10**can span**10 feet and so on.

Correspondingly, how far can you span LVL?

Measure your total **span** between members and ensure that it is not greater than 60 feet. Because of transport limitations, the maximum standard length for manufactured beams is sixty feet.

**will**see that a

**4**-

**ply**, 2 X 12

**can span**a maximum of 13' while supporting 12' joists on either side of it.

Considering this, what size LVL Do I need to span 20 feet?

Re: **20** foot clearspan beam **size** Then your floor joists only **need to span** 8' between the wall and the "beam" (or between the beams). In that case, you **need** something like a 12-16" GLULAM or **LVL** to **span** the **20**' and can use simple 2x8-10 dimensional lumber 16"OC as floor joists.

**LVL** has a “maximum allowable bending stress” of 2,800 or 3,000 psi. And according to this source, most wood has a maximum bending stress of about half that. So, yes. LVLs will bear more weight than the same size wood **beam**.
