Framing A Garage Door

Garage Door Framing

Framing a garage door is like setting the foundation of a house. It sets the stage for all the other parts to play their roles effectively. In essence, it creates the structural support needed for the door to operate efficiently and safely.

  • Measurements: The first step in garage door framing involves taking the correct measurements. For a standard door, you'll need to measure the width and height of the door and add an additional 3 inches to each side for the frame. This ensures that you have ample space for the door, tracks, and weather stripping.
  • Material Selection: Once you have your measurements, it's time to choose the materials for your frame. Usually, this involves using lumber of a suitable size. Many people opt for 2x4s or 2x6s, depending on the size and weight of the door.
  • Framing: Once you have your measurements and materials, it's time to build the frame. Start by installing the vertical pieces on each side of the opening, ensuring they are plumb. Then, install the horizontal piece, known as the header, at the top.

Below is a comparison table of 2x4 and 2x6 lumber to help you decide which is best for your project.

Lumber TypePros Cons
2x4Lighter, cheaper, easier to work withLess sturdy, may not be suitable for heavy doors
2x6Sturdier, ideal for heavy doorsMore expensive, heavier, harder to work with

Garage Door Framing Detail

Details matter a lot when it comes to garage door framing. The devil is indeed in the details. Understanding these details can make a significant difference in the quality and longevity of your garage door installation.

  • King and Jack Studs: These are the vertical supports on the sides of the garage door framing. The king stud runs from the bottom of the sill to the top plate, while the jack stud is attached to the king stud and supports the header.
  • Header: This is the horizontal piece that runs across the top of the frame. It's essential for providing structural support and distributing the load from above.
  • Sill: The sill is the bottom part of the frame, where the door sits when closed.
  • Trim: This is the finishing touch to the frame, added for aesthetic purposes and to seal any gaps between the door and the frame.

Here's a comparison table of the components and their roles:

Garage Door Header Framing

The garage door header is arguably one of the most crucial parts of the framing. It supports the load from above and distributes it evenly to the vertical components (king and jack studs) of the frame. The size of your header will depend on the load it needs to bear.

A common mistake is under sizing the header, which can lead to sagging and structural issues down the line. Always refer to local building codes or consult a structural engineer if you're unsure about the size of the header needed.

  • Header Sizing: As a general rule, headers for garage doors up to 9 feet wide should be at least 2x6s, and headers for doors up to 16 feet wide should be 2x12s. However, these sizes can vary based on load and local building codes.
  • Header Installation: The header should be installed level and directly on top of the jack studs. It should be secured with suitable fasteners.
  • Extra Support: For wider doors or in areas with heavy snow loads, extra support may be needed. This can come in the form of a doubled-up header or a steel lintel.

Framing for Garage Door Opening

The opening of a garage door is essentially a hole in the wall of your garage. However, this "hole" needs to be structured perfectly to ensure the smooth operation of the garage door.

  • Measurement: Measure the width and height of your garage door. Add 3 inches on each side and at least an inch and a half on top for the opening.
  • Marking: Use chalk or a pencil to mark the opening on the wall. This will be your guide when cutting and framing the opening.
  • Cutting and Framing: Use a saw to cut along your marked lines, then build your frame according to the previous sections of this article.

Framing a garage door opening is critical and, when done correctly, ensures that your garage door operates smoothly and efficiently.

How Much Does It Cost?

The cost of garage door framing can vary greatly depending on a number of factors. Understanding these factors can help you budget appropriately for your project.

  • Materials: The cost of the materials is a major factor in the total price of framing a garage door. Common materials used for framing include wood, typically in the form of 2x4 or 2x6 lumber. The cost can range from $1 to $3 per linear foot, depending on the type and quality of the wood. Additionally, the cost of nails, screws, and weather stripping should also be considered.
  • Size of the Garage Door: The larger the door, the more materials you'll need for framing, which will increase the cost. A standard single garage door requires less framing material than a double garage door.
  • Labor: If you're hiring a professional to do the framing, labor costs will be a significant portion of the total expense. Labor costs can vary based on the complexity of the job and the region you live in, but they typically range from $30 to $50 per hour.
  • Local Building Codes: Depending on your local building codes, additional elements may be required for your garage door frame, which can increase the overall cost.
  • Existing Structure Conditions: If the existing structure requires modifications or repairs before the framing can be installed, this will also affect the cost. For example, removing old framing or correcting structural issues can add to the project's cost.

Here's a rough comparison chart for the cost of framing a single vs. a double garage door, including materials and labor:

Garage Door SizeMaterial CostLabor CostTotal Cost
Single (9 x 7 feet)$60 - $100$150 - $200$210 - $300
Double (16 x 7 feet)$100 - $150$200 - $250$300 - $400

Please note, these figures are estimates and actual prices can vary significantly based on the factors mentioned above. Always get a detailed quote from your contractor before starting a project. If you're undertaking the project yourself, thorough planning and budgeting are key.

What Is the Purpose Of Garage Door Framing?

Garage door framing serves several vital purposes that contribute to both the functionality and safety of your garage door. Here's a closer look at why it's so important:

  • Structural Support: The primary purpose of garage door framing is to provide necessary structural support. It forms the "skeleton" of the garage door opening, giving the door and its components something sturdy to attach to. This ensures that the door can operate smoothly, whether it's being opened or closed.
  • Ensuring Correct Fit: Framing also ensures that the garage door fits correctly into the space. By providing a precise frame for the door, you can avoid issues such as gaps that can allow in drafts, water, or pests.
  • Load Distribution: Another crucial role of the garage door frame, particularly the header, is load distribution. It supports the weight from the top of the structure, distributing it evenly to the vertical components of the frame. This prevents undue stress on the garage door and its components.
  • Safety: Proper garage door framing promotes safety. A poorly framed door can lead to operational issues and even potential collapse, posing a significant risk.
  • Aesthetic Appeal: Lastly, well-done garage door framing can enhance the overall appearance of your garage and, by extension, your home, contributing to curb appeal.

Errors to Avoid During the Garage Door Framing

Garage door framing might seem like a straightforward process, but it's often fraught with common errors that can significantly impact the functionality and safety of your door. Here are some of the most frequent mistakes and their potential effects:

Incorrect Measurements

One of the most common mistakes made during garage door framing is incorrect measurements. Taking inaccurate measurements can result in a garage door frame that's too small or too large for the actual door. 

If the frame is too small, the door may not fit, or it might rub against the frame, causing damage over time. Conversely, if the frame is too large, you'll end up with gaps that let in drafts and may compromise security.

Not Checking for Square

After the frame is installed, it's important to check that it's square. An out-of-square frame will lead to a door that doesn't hang or operate correctly. The door may bind, causing it to stick or stop, which could lead to long-term damage to the door mechanism.

Insufficient Header Support

Headers play a crucial role in supporting the weight from the top of the structure and evenly distributing it to the vertical components of the frame. If the header is undersized or not properly installed, it could lead to sagging over time. 

This could compromise the structural integrity of not only the garage door but also the entire garage itself. In extreme cases, it could result in the collapse of the top portion of the door.

Neglecting Weather Stripping

Another common oversight during the garage door framing process is neglecting to include adequate weather stripping. Proper weather stripping is necessary to seal the gaps between the garage door and the frame, preventing drafts, rain, snow, and pests from entering the garage. A lack of appropriate weather stripping can lead to damage from moisture or temperature changes and an increase in energy costs due to heat loss.

Ignoring Local Building Codes

Local building codes exist to ensure the safety and effectiveness of construction projects, including garage door framing. Ignoring these codes can result in a structurally unsound frame, posing potential hazards. Non-compliance can also lead to fines and could necessitate costly redoing of the work to meet standards.

Choosing the Wrong Material

The materials used for framing should be strong and durable. Using low-quality materials or ones not suited to the specific type of door (e.g., using a 2x4 header for a heavy, double-wide door) can lead to instability and potential failure of the door system.

Avoiding these common mistakes can go a long way toward ensuring a safe and efficient garage door. Proper garage door framing is essential to the operation of the door and the overall structural integrity of your garage. It's always a good idea to double-check measurements, materials, and codes and consult professionals if you're uncertain.


In conclusion, garage door framing may seem daunting, but with the right information and tools, you can take on the task with confidence. Remember, the strength and stability of your garage door hinge heavily on the frame you build for it. Paying attention to garage door framing details, understanding the role of a garage door header, choosing the right framing for your garage door, and framing the garage door opening correctly are all crucial to achieving a garage door that works flawlessly for years. So take the time, do it right, and your garage door will thank you!
