The maximum span for 2×6 joist is 3ft.

The “floor joist span calculator” is a tool that can help you determine the maximum span for your floor joists. The span of a floor joist is the distance from one side of the beam to the other, and is measured in feet.

Furthermore, how far can a 2×6 Rafter be span?

The table states that 6 x 2 rafters spaced 16 inches on center (o.c) can span a maximum distance of 13 feet 5 inches. Another option are 8 x 2 rafters spaced 24 inches o.c.

Spans are clear lengths between supports based on composite action with glued-nailed APA Rated® sheathing or Sturd-I-Floor® panels of minimum thickness 1932 (40/20 or 20 o.c.) for joist spacing of 19.2 or less, or 2332 (48/24 or 24 o.c.) for joist spacing of 24 or more.

Furthermore, how far can a triple 2×6 be stretched?

The maximum spread for a single 2×6 #2btr yellow pine is roughly 9′ feet, thus a triple 2×6 beam over a span of 10′ feet should be more than enough for regular deck loads.

What is the maximum load that a 2×6 can handle?

The sort of load will also decide how much weight a 2×6 can sustain on its edge; for example, a 2×4 timber may easily carry a 4-cylinder engine but not a larger one, but a 2×6 may support a V8 engine weighing between 600 and 700 lbs.
