Load Bearing Header Size Chart: The Ultimate Guide to Choosing the Right Size

Gone are the days when choosing the right load-bearing header size chart was a daunting task. With our comprehensive guide, you'll have all the knowledge you need to make an informed decision. Whether you're a seasoned contractor or a homeowner looking to DIY, this article will provide you with the insights you need for a successful project.

Step 1: Determine the Load

Before selecting a header size, it's crucial to calculate the load it will bear. This involves considering the weight of the materials being supported, as well as any potential live loads (e.g., people, furniture). According to the National Association of Home Builders, the average roof load in the United States is 20 pounds per square foot (psf).

Load Type	Load (psf)
Dead Load (roofing materials)	5 - 10
Live Load (occupants, furniture)	10 - 20
Snow Load (varies by region)	0 - 50

Step 2: Choose the Header Size

Once you know the load, you can refer to a load-bearing header size chart to determine the appropriate size. These charts provide recommended header sizes based on the load and span (distance between supports).

Span (feet)	Header Size (inches)	Load (psf)
6	2x6	200
8	2x8	300
10	2x10	400

Effective Strategies

Consider using engineered lumber (e.g., LVL, glulam) for increased strength and stiffness.

Double up headers for spans over 12 feet or for heavy loads.

Install headers flush with the framing to provide maximum support.

Common Mistakes to Avoid

Underestimating the load on the header.

Choosing a header size that is too small for the span.

Not using proper support for long spans.

By following these tips and using our load-bearing header size chart, you can ensure that your headers will safely support the load and last for years to come.
