Selecting the Right Header Size for a 10 Foot Span
When it comes to choosing a header for a 10 foot span, there are several factors to consider. The size of the header will play a significant role in determining the overall aesthetic and structural integrity of the doorway or opening. In this article, we will explore the various factors that influence the selection of a header size and provide guidance on how to choose the right one for your specific needs.
Factors to Consider When Selecting a Header Size
The size of the header is determined by the span, which is the distance between the two sides of the doorway or opening. In this case, the span is 10 feet. Other factors that influence the header size include the type of materials used, the weight of the materials, and the intended use of the doorway or opening.
Types of Headers
There are several types of headers that can be used for a 10 foot span, including:

- Wooden headers: Made from wood, these headers are a popular choice for residential and commercial construction projects.
- Steel headers: Made from steel, these headers are a popular choice for heavier loads and larger spans.
- Pre-fabricated headers: Made from a variety of materials, these headers are a convenient and cost-effective option for many projects.
Header Size Considerations
The size of the header will depend on the type of materials used and the weight of the materials that will be bearing down on it. As a general rule, the header should be at least 2 inches deeper than the joist it is spanning, and should have a minimum thickness of 2x4s or 2x6s for wooden headers.
Steel headers, on the other hand, can be thinner, but should still be at least 12 inches deep to ensure adequate support. Pre-fabricated headers, which are often made from a combination of materials, will typically have specific sizing requirements that should be followed.
Header Size Charts and Tables
Below is a table outlining the recommended header sizes for a 10 foot span:

| Material | Minimum Thickness | Minimum Depth |
|---|---|---|
| Wood | 2x4 | 10 inches |
| Steel | 12 gauge | 12 inches |
| Pre-fabricated | Varies by manufacturer | Varies by manufacturer |
Additional Considerations
In addition to the size of the header, there are several other factors to consider when selecting a header for a 10 foot span. These include:
- The weight of the materials that will be bearing down on the header.
- The type of load the header will be carrying (e.g. dead load, live load).
- The desired level of structural integrity and support.
- The aesthetic considerations of the header (e.g. visibility, finish).
Conclusion is Not Necessary
By considering the factors outlined in this article, homeowners and builders can select the right header size for their 10 foot span doorway or opening. Whether you choose a wooden, steel, or pre-fabricated header, be sure to follow the recommended sizing requirements and consult with a professional if you are unsure about the best choice for your specific project.
