The maximum distance a 2×6 can span, according to the 2018 IRC, for a floor joist, is 12′-6”, ceiling joist 20′-8”, rafter 18′-0”, deck board 24”, deck joist 9′-11”, deck beam 8′-3”, and 6′-1” as for header. Always check the codes for determining factors or consult a Structural Engineer.

How far can a 2×6 span without support for a roof?
A 2×6 rafter can span 14 feet 8 inches when spaced 16 inches apart with No. 1-grade southern pine lumber on a roof with a 3/12 slope or less with a maximum live load of 20 pounds per square foot and a dead load of 15 psf.
What distance can you span with a 2×6?
A 2×6 joist can span anywhere between 8′ for Cedar and Redwood to 9′ for Pine and Fir at 16″ OC. 12″ OC yields longer spans, while 24″ OC allows shorter spans.
How much load can a 2×6 support?
A single SPF#2, 9′ x 2×4 that’s restrained by sheathing or blocking can support 1820 lbs and a similar 2×6 that’s not restrained can support 7061 lbs.
Can 2×6 be used for rafters?
You can use either 2×6 or 2×4 rafters for roofs with a 3/ 12 pitch or greater, but it depends on the overall size of your shed. For roofs that won’t experience heavy snow loads, a gable roof can span up to 22′ with 2×4 rafters.
Is 2×6 good for floor joist?
Yes, 2 X 6 lumber can be used for floor joists, but the allowable clear span is only about 4 or 5 feet. Such a small span is seldom useful.
How far can a triple 2×6 beam span?
For normal deck loads, a triple 2×6 beam over a span of 10′ feet should be enough. The maximum span is 9′ feet for a single 2×6 #2btr yellow pine. You should be fine with triple 2×6.
Which is stronger 2×6 or 4×4?
The single 2×6 is 68% stronger than the 4×4 for vertical loads as you describe. However, I caution you that it may be a good idea to have someone design this beam properly so the job is done right. If you’re willing to have a 4″ wide beam, why not create a double 2×6 beam, this will be 237% stronger!
What is stronger 4×6 or 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).
How much weight can a 2×6 deck hold?
In short there’s no one right answer to “how much can my deck hold?” However, one rule of thumb to keep in mind while answering the question is that the answer commonly is that if a deck is properly designed, it’s built to hold 50 lbs. per square foot.
How far can a 2×6 span for a patio roof?
The smallest beams for patio covers are typically 4-by-6. In general, the maximum span for a 4-by-6 beam is 6 feet between 4-by-4 posts.
What size beam do I need for a 14 foot span?
How big of a beam do I need to span 14 feet? According the charts I have, you would need a 6×12 beam on each side to support 7680 pounds over a 14 ‘ span (assuming you want less than a 1/360 deflection).
How far can a 2×6 cantilever?
Looking at the table below, we see that 2×6 floor joists can be cantilevered up to 2 feet and 6 inches (2′-6″) when the joists are spaced 16″ apart. The table also indicates that we need to keep the length of the joist that is not cantilevered between 4′-0″ and 6′-6″.
