2x12 lumber is commonly used in construction projects for structural framing, such as floor joists, roof rafters, and stair stringers. It is also used for building large beams and headers to support heavy loads in buildings.
Standard lumber measurements used in construction projects include 2x4, 2x6, 2x8, 2x10, and 2x12, which refer to the dimensions of the lumber in inches. These measurements are commonly used for framing and structural components in buildings.
The 2x12 span chart provides information on the maximum allowable span for a 2x12 lumber based on the load it will support.
For stair stringers, it is recommended to use 2x12 lumber for optimal strength and support.
The maximum span of a 2x12 lumber depends on several factors, including the wood species, load conditions, and whether it is used as a floor joist or beam. Generally, for standard residential applications with a uniform load, a 2x12 can span approximately 12 to 16 feet. However, it's crucial to consult local building codes and a structural engineer for specific requirements and safety considerations.
it's 2: 2x8 = 16 and 2x12= 24
The best ways to use 2x12 boards in a woodworking project are for building sturdy shelves, constructing furniture like benches or tables, creating outdoor structures such as decks or pergolas, and making large-scale projects like workbenches or storage units. The thickness and width of 2x12 boards make them ideal for supporting heavy loads and providing stability in various woodworking projects.
Their least common multiple is 24. (2x12=24, 6x4=24, 8x3=24.)

A 2x12 LVL (Laminated Veneer Lumber) is generally stronger and more suitable for longer spans than OSB (Oriented Strand Board). For an 18-foot span in a lean-to carport, a 2x12 LVL would likely be more appropriate, as it can support heavier loads and provide better structural integrity. OSB is typically used for sheathing or flooring rather than as a primary structural member. Always consult local building codes and a structural engineer for specific requirements.
Usually it is in a 2x4 wall. Take two 2x12's the right length and put a strip of 1/2 inch thick plywood between them. Nail through from each side at regular points alternating the spacing on each side. This ties everything together. The plywood and the different grains of the 2x12 give it more strength than the parts separately. good answer above. make sure to crown both 2x12's in the same direction and adding construction adhesive to plywood before nailing all together gives it even more strength. Install it with crowned side up naturally!
The width is 2 in this case.
