how far can you span a 2×6

The maximum span for a 2×6 depends on several factors, including:

1. Load: The weight and type of load the beam will be supporting (e.g., roof, floor, wall).
2. Grade: The type and quality of the lumber (e.g., #1, #2, pressure-treated).
3. Orientation: Whether the beam is installed horizontally (e.g., as a joist) or vertically (e.g., as a stud).
4. Spacing: The distance between adjacent beams.

Here are some general guidelines for maximum spans for 2×6 lumber:

Roof Rafters:

• 2×6 #1 grade: 14-16 feet (4.3-4.9 meters) for a 20 psf (pounds per square foot) load
• 2×6 #2 grade: 12-14 feet (3.7-4.3 meters) for a 20 psf load

Floor Joists:

• 2×6 #1 grade: 10-12 feet (3-3.7 meters) for a 40 psf load
• 2×6 #2 grade: 8-10 feet (2.4-3 meters) for a 40 psf load

Deck Joists:

• 2×6 #1 grade: 8-10 feet (2.4-3 meters) for a 40 psf load
• 2×6 #2 grade: 6-8 feet (1.8-2.4 meters) for a 40 psf load

Wall Studs:

• 2×6 #1 grade: 10-12 feet (3-3.7 meters) for a 20 psf load
• 2×6 #2 grade: 8-10 feet (2.4-3 meters) for a 20 psf load

Keep in mind that these are general guidelines and may vary depending on local building codes, regulations, and specific design requirements. It’s always best to consult with a structural engineer or a qualified builder to determine the maximum span for a specific application.
