# How much load can a 2x6 support?

**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.

Subsequently, one may also ask, how much weight can you hang from a 2x6?

So the area between two 2x6, 6' long, on 2' intervals would have to be able to support 2x6x40=**480 pounds** of weight. Actually, slightly more since the formula is for 8'-6" spans but it just gives you a little bit of extra load for just in case.

**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).

Also to know is, how far can a 2x6 span 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. The larger the deck, the larger the joists.

some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s **are** generally used for ceiling joists, esp since you said 24" oc and reallllly short spans only (5 or 6 feet ). Most floor loads **would** be a minimum of **2x8** @ 16" oc and most preferbaly 2x10.
