The answer to this question is too complex to describe here. There are too many factors which are not specified in the question, such as load in pounds per linear foot, spacing of the 4X12 joists, as well as grade and species of lumber.

The span of a 4 x 8 wood beam depends on various factors, including the type of wood, the load it needs to support, and local building codes. Generally, a properly sized 4 x 8 beam can span approximately 10 to 12 feet when supporting light loads, such as a patio cover. However, for specific applications, it's essential to consult a structural engineer or refer to local building codes to ensure safety and compliance.
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.

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.
The recommended patio roof beam span according to the patio roof beam span table is typically around 10-12 feet.
The recommended pergola beam span according to the pergola beam span chart is typically around 12-16 feet, depending on the specific design and materials used.
The maximum span for a 6x8 beam depends on various factors, including the material (e.g., wood, steel), load conditions, and support type. Generally, for a standard wood beam, a 6x8 beam can typically span around 10 to 12 feet for residential applications with a uniform load. However, it is essential to consult local building codes and a structural engineer for specific guidelines and calculations relevant to your project.
Only if it is at least 12' long.
A double 2x10 beam can typically span up to 12 feet without additional support.
It depends on what the beam is made of.
Depends on the loads and the properties of the beam. Consult a structural engineer.
The maximum span for a double 2x12 beam made of pine can vary depending on factors such as load requirements, local building codes, and spacing of supports. Generally, for residential applications, a double 2x12 can span approximately 12 to 16 feet when used as a beam. However, it's crucial to consult local building codes and a structural engineer for specific requirements and load calculations.
