## How big of a beam 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 2×8-10 dimensional lumber 16″OC as floor joists.

## 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).

Kaiden;as Daniel said, the two 2×6’s will be slightly stronger than one 2×8. (I think by around 10%). However, whether or not they will work for your situation depends on the loading stipulation and deflection limits for your floor, which presumably is in your Code.
