The type of load in question

**will**also determine**how much**weight a**2x6 can**hold on edge. For example, a 2x4 lumber may hold a 4-cylinder engine comfortably but may not hold a bigger one. On the other end, a**2x6 can**support a V8 engine of between 600 – 700 lbs.

Correspondingly, what is stronger 4x6 or 2 2x6?

A **4x6** joist is theoretically **stronger** than a doubled **2x6** 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).

**of two 2x6's**(true dimension 1.5 inches x 5.5 inches) are slightly

**stronger than**a single

**2x8**true dimensions 1.5 inches by 7.25 inches.

Additionally, how far can you span a 2x6 without support?

In general terms, joists spaced 16 inches on center **can span** 1.5 times in feet their depth in inches. A **2x8** up to 12 feet; 2x10 to 15 feet and 2x12 to 18 feet.

Max. Live Load 20 lbs/ft2 (956 N/m2)
