The Door Header Size Chart provides information on the header sizes required for single and double doors based on different door sizes. It includes door sizes such as 2'-6" x 6'-8", 2'-8" x 6'-8", 3'-0" x 6'-8", 2'-6" x 8'-0", and 2'-8" x 8'-0" along with corresponding header sizes in inches for both single and double doors.
Chart Data
| Door Size | Header Size (Single) | Header Size (Double) |
|---|---|---|
| 2′-6″ x 6′-8″ | 4-9/16″ | 9-1/4″ |
| 2′-8″ x 6′-8″ | 4-9/16″ | 9-1/4″ |
| 3′-0″ x 6′-8″ | 4-9/16″ | 9-1/4″ |
| 2′-6″ x 8′-0″ | 4-9/16″ | 9-1/4″ |
| 2′-8″ x 8′-0″ | 4-9/16″ | 9-1/4″ |
Conclusion
The Door Header Size Chart shows that for various door sizes, both single and double door header sizes remain consistent at 4-9/16" and 9-1/4" respectively, providing a standard reference for framing requirements.
FAQ
What is the standard size for a door header in residential construction?
The standard size for a door header in residential construction is typically 2x6 lumber for openings up to 3 feet wide, and 2x8 lumber for wider openings.
How do you determine the required size for a door header?
The required size for a door header is determined by factors such as the span of the opening, the load it needs to support, and local building codes. A structural engineer or architect can help calculate the appropriate header size.
Can a door header be made of materials other than wood?
Yes, door headers can also be made of steel or engineered wood products like LVL (laminated veneer lumber) for greater strength and load-bearing capacity.
Do all doors require a header?
Yes, all doors require a header to support the weight of the structure above the opening and distribute it to the adjacent walls.
Are there building code requirements for door header size?
Yes, building codes specify minimum requirements for door header size based on factors such as the span of the opening, the type of construction, and the load it needs to support. It's important to comply with these codes to ensure structural integrity and safety.
