One 2x12 can support about

**180 lbs**. per foot or about**2,100 lbs**. total for a 12' span.

Keeping this in consideration, how far can you span a 2x12 beam?

A double **2x12 beam can span** 12 feet; a (2) 2x10 **can span** 10 feet and so on.

**hold**around 150 pounds per foot x length x spans but then at some point you get into mode of rupture or elastics, dead

**weight**live

**weight**.

Accordingly, what size lumber can span 20 feet?

Re: **20** foot clearspan beam **size** 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.
