Header Span Load Bearing Header Size Chart: The Ultimate Guide for Construction Professionals
As a construction professional, understanding header span load bearing header size charts is crucial for ensuring the structural integrity of your projects. This guide will provide you with the essential information you need to choose the right header for your specific needs.
Header Span Load Bearing Header Size Chart
The following table shows the maximum span for headers of various sizes and materials.
| Header Size (Width x Height) | Maximum Span (Feet) |
|---|---|
| 2x6 | 6 |
| 2x8 | 8 |
| 2x10 | 10 |
| 2x12 | 12 |
Note: These values are for headers made of SPF (spruce-pine-fir) lumber. For other lumber species, consult a structural engineer.
Header Load Capacity
The load capacity of a header is determined by its size, material, and span. The following table shows the load capacity for different headers.
| Header Size (Width x Height) | Load Capacity (Pounds) |
|---|---|
| 2x6 | 1,200 |
| 2x8 | 1,800 |
| 2x10 | 2,400 |
| 2x12 | 3,000 |
Note: These values are for headers made of SPF lumber with a span of 8 feet. For other span lengths, consult a structural engineer.
Story 1: Benefits of Using a Header Span Load Bearing Header Size Chart
- Ensures structural integrity: Using the correct header size for the span and load will prevent the header from sagging or failing.
- Saves time and money: By selecting the appropriate header size, you can avoid costly repairs or replacements in the future.
- Improves safety: A properly sized header will support the weight of the wall above it, preventing injuries from structural failure.
How to Use a Header Span Load Bearing Header Size Chart:
- Determine the span of the header. This is the distance between the supports (usually walls or columns).
- Calculate the load that the header will support. This includes the weight of any walls, windows, doors, or other structures above it.
- Refer to the chart to select the appropriate header size for the span and load.
Story 2: Making the Right Choice for Your Project
Consider the following factors when choosing a header:
- Span: The span of the header will determine the size and strength required.
- Load: The load that the header will support will determine the material and thickness required.
- Framing type: The type of framing (studs, joists, etc.) above the header will affect its load capacity.
Tips and Tricks
- Use a stronger material (e.g., LVL beams) for longer spans or heavier loads.
- Double up headers to increase their load capacity.
- Install headers perpendicular to the wall framing for maximum support.
- Consult with a structural engineer for spans over 8 feet or loads over 3,000 pounds.
