Load Bearing Header Size Chart: Choosing the Right Size for Your Exterior Wall
Load Bearing Header Size Chart: Choosing the Right Size for Your Exterior Wall
When building or remodeling an exterior wall, selecting the correct load-bearing header size is crucial for ensuring structural integrity. These headers support the weight of the wall above, preventing it from collapsing. Choosing an inadequate size can compromise the building's safety and stability.
Refer to our comprehensive load-bearing header size chart for exterior walls below, which outlines the recommended header sizes based on the span of the opening and the weight of the wall.
| Opening Span | Header Size | Weight of Wall |
|---|---|---|
| Up to 6 feet | 2x8 | 500 lbs/foot |
| 6-8 feet | 2x10 | 750 lbs/foot |
| 8-10 feet | 2x12 | 1,000 lbs/foot |
| 10-12 feet | 2x14 | 1,250 lbs/foot |
| Opening Span | Header Size | Weight of Wall |
|---|---|---|
| Up to 4 feet | 2x6 | 250 lbs/foot |
| 4-6 feet | 2x8 | 500 lbs/foot |
| 6-8 feet | 2x10 | 750 lbs/foot |
| 8-10 feet | 2x12 | 1,000 lbs/foot |
| 10-12 feet | 2x14 | 1,250 lbs/foot |

Effective Strategies, Tips, and Tricks
- Use the load-bearing header size chart as a starting point but consult a structural engineer for complex or unusually heavy wall designs.
- Consider the weight of any fixtures or equipment that will be attached to the wall when determining the appropriate header size.
- Choose header material that meets or exceeds the recommended specifications for strength and durability.
- Install the header according to manufacturer's instructions and ensure it is adequately supported by the surrounding framing.
Common Mistakes to Avoid
- Undersizing the load-bearing header can lead to structural failure and collapse.
- Oversizing the header is unnecessary and can waste materials and increase construction costs.
- Installing the header incorrectly can compromise its structural integrity and create safety hazards.
