If you’re planning on building a structure with a 12 foot span, you’ll need to use a header that’s at least 12 inches wide. But what size header do you need for a 12 foot span? Read on to find out!

Measuring the Header
To know what size header you need for a 12 foot span, you will need to take some measurements. You will need to measure the width of the opening, the thickness of the material, and the length of the span. With these measurements, you will be able to determine the size header you need.
Determine the span of the header.
In order to determine the span of the header, you will need to measure the distance between the two supporting walls. If the span is 12 feet, then you will need a header that is at least 12 inches wide. The wider the header, the stronger it will be.
Find the width of the header.
The header is the horizontal beam that supports the weight of the house above the window or door opening. To find the width of the header, measure the distance between the king studs on either side of the opening. The header should be at least as wide as this distance, but no wider than twice this distance. The standard width for a two-story house is 10 feet, so a 12-foot span would require a header that is at least 10 feet wide.
Determine the height of the header.
There are a few key factors you need to consider when determining the size of header you need for a 12 foot span. The first is the load – how much weight will be placed on the header? The second is the span – how long is the distance between the two support beams? And the third is the material – what type of material will the header be made out of?
Once you have considered all of these factors, you can use a beam size chart to determine the size of header needed for a 12 foot span. For example, if you are using a light load and a short span, you may only need a 2×6 header. However, if you are using a heavy load and a long span, you may need a 2×12 header. ultimately, it is important to consult with a structural engineer to ensure that yourheader is properly sized for your project.
Types of Header
There are several types of header that can be used for a 12 foot span. The most common type of header is the engineered header. This type of header is composed of trusses that are placed on top of the wall studs. The second type of header is the built-up header. This type of header is made by attaching pieces of lumber together to form a beam.
Standard header
If you are building a home or other structure with a span of 12 feet, you will need to use a standard header. This header is also sometimes called a double 2×12 header. This type of header is made up of two 2×12 boards that are nailed or screwed together side by side. The standard header is the most common type of header used in construction.
Truss header
A truss header is a type of header that is used to support a truss span. Truss headers are typically made from lumber that has been laminated together to form a strong, rigid beam. The laminates in a truss header are usually oriented at different angles to each other, which gives the header its strength. Truss headers are often used in spans that are too long for a conventional header to support, such as spans that exceed 12 feet.
Engineered header
An engineered header is a prefabricated wood product that is sized to span a specific distance and support a predetermined load. Engineered headers are manufactured to meet the requirements of the Building Code, which sets minimum standards for safety. The span and load requirements of each type of engineered header are stamped on the product label.
It is important to select an engineered header that is designed for the specific span and load requirements of your project. For example, a 2×8 engineered header can span up to 8 feet and support up to 60 pounds per square foot (psf). A 2×10 engineered header can span up to 10 feet and support up to 40 psf.
When selecting an engineered header, it is also important to consider the type of wood that is best suited for your project. For example, Douglas fir is a popular choice for headers because it has good strength and stiffness properties. However,Douglas fir is not as resistant to rot and insect damage as some other types of wood, so it may not be the best choice for an exterior application.
Sizing the Header
You will need a 2×10 header for a 12 foot span. The header should be made of two 2x10s nailed together on each end with 16d nails. The header must be installed correctly in order to support the weight of the roof.
Standard header
The standard header size for a 12 foot span is 2×4.
Truss header
The size of the header you need for a 12 foot span depends on the load bearing capacity of the trusses. To calculate the load bearing capacity, you need to know the span, the rise, and the run of the trusses. The span is the length of the header, the rise is the height of the header, and the run is the width of the header. The load bearing capacity is calculated by multiplying the span by the rise by the run. For example, if your trusses have a span of 12 feet, a rise of 2 feet, and a run of 4 feet, your header would need to be able to support a load of 96 pounds.
Engineered header
When it comes to headers, size matters. An engineered header is a pre-fabricated wood product that is specifically designed to support the weight of a house and the loads imposed by wind and seismic activity. The size of a header is determined by the span (the distance between two supports), the weight of the house and the loads imposed by wind and seismic activity.
For a 12-foot span, you will need a header that is at least 24 inches deep and 6 inches wide. If you are using an engineered header, you will need to follow the manufacturer’s instructions for sizing and installation. If you are using a traditional board or beam, you will need to consult with a structural engineer to determine the appropriate size for your particular application.
