Header Span Load Bearing Header Size Chart: The Ultimate Guide
Header Span Load Bearing Header Size Chart: The Ultimate Guide
Are you planning a construction project that requires a load-bearing header? If so, you'll need to choose the right size header for the job. A header is a structural element that spans an opening in a wall or roof and supports the load above it. Headers are typically made of wood, steel, or concrete.
The size of a header depends on a number of factors, including the span of the opening, the load that it will be supporting, and the type of material that it is made of.
Span of the Opening
The span of the opening is the distance between the two supports for the header. The longer the span, the larger the header will need to be.
Load
The load that a header will be supporting includes the weight of the materials above it, such as the wall or roof, as well as any other loads that may be applied, such as snow or wind. The heavier the load, the larger the header will need to be.
Material
The type of material that a header is made of will also affect its size. Wood headers are typically smaller than steel or concrete headers because wood is a less strong material.
Header Span Load Bearing Header Size Chart
The following table provides a general guide to the size of header that you will need for a given span and load.
| Span (ft) | Load (lbs) | Header Size (in.) |
|---|---|---|
| 4 | 1,000 | 2x6 |
| 6 | 1,500 | 2x8 |
| 8 | 2,000 | 2x10 |
| 10 | 2,500 | 2x12 |
| 12 | 3,000 | 3x10 |
Success Stories
- A contractor used a header span load bearing header size chart to select the right size header for a new home construction project. The header was able to support the weight of the roof and walls, and the home was built successfully.
- A homeowner used a header span load bearing header size chart to select the right size header for a new deck. The header was able to support the weight of the deck and the people on it, and the deck was built successfully.
