How do I measure for a door awning?
Sep 17, 2025| Measuring for a door awning is a crucial step in ensuring that you get the perfect fit for your doorway. As a door awning supplier, I've seen firsthand the importance of accurate measurements. In this blog post, I'll guide you through the process of measuring for a door awning, so you can make an informed decision when it comes to purchasing one.
Why Accurate Measurements Matter
Before we dive into the measurement process, let's understand why accurate measurements are so important. A well - measured door awning not only enhances the aesthetic appeal of your home but also provides optimal functionality. If the awning is too small, it won't provide adequate protection from the elements. On the other hand, if it's too large, it can look out of place and may even cause installation issues.
Tools You'll Need
To measure for a door awning, you'll need a few basic tools:
- A tape measure: A good quality tape measure, preferably one that is at least 25 feet long, will be essential for getting accurate measurements.
- A level: This will help you ensure that the awning is installed straight.
- A pencil and paper: To jot down your measurements and any notes.
Step 1: Measure the Width of the Door
The first step is to measure the width of the door. Start by measuring the distance from one side of the door frame to the other at the top, middle, and bottom of the door. It's common for door frames to have slight variations in width, so taking multiple measurements will give you a more accurate average.
Write down these measurements and then calculate the average. This average width will be the minimum width for your awning. However, it's often recommended to add a few extra inches (usually 6 - 12 inches) on each side for better coverage. This additional width will protect the door and the area around it from rain and sun.
Step 2: Measure the Height from the Door to the Desired Awning Location
Next, you need to measure the height from the top of the door frame to the location where you want to install the awning. This measurement will determine the drop or the vertical length of the awning.
Again, take multiple measurements at different points along the door frame to account for any irregularities. Make sure to measure from a straight, level point on the wall. If you're installing the awning above the door, measure from the top of the door frame to the desired mounting height on the wall.
Step 3: Consider the Projection of the Awning
The projection of the awning refers to how far it extends out from the wall. The amount of projection you need depends on your specific needs. If you want to protect a large area in front of the door from rain and sun, you'll need a larger projection.


A common projection for door awnings ranges from 2 to 4 feet. However, this can vary based on the style of the awning and the amount of space available in front of the door. Measure the available space in front of the door to ensure that the awning projection you choose won't cause any obstructions.
Step 4: Check for Obstructions
Before finalizing your measurements, it's important to check for any obstructions that may affect the installation of the awning. Look for things like light fixtures, security cameras, or other wall - mounted objects that could get in the way.
If there are obstructions, you may need to adjust your measurements or choose a different style of awning that can accommodate these obstacles. For example, some awnings can be installed with a custom - cut to avoid hitting a light fixture.
Step 5: Account for the Style of the Awning
Different styles of awnings have different installation requirements. For example, a retractable awning may require more space for the housing unit when it's retracted. A fixed - frame awning may need a more sturdy mounting structure.
When measuring, make sure to consider the style of the awning you're interested in. If you're unsure, you can consult our experts who can guide you based on the style and your specific measurements.
Different Types of Door Awnings and Their Considerations
There are several types of door awnings available, each with its own unique features and measurement considerations.
Door Canopy Kit
A Door Canopy Kit is a popular choice as it often comes with all the necessary components for easy installation. When measuring for a door canopy kit, you need to ensure that the width and height measurements match the specifications of the kit. Some kits may have a limited range of sizes, so accurate measurements are crucial to find the right fit.
Glass Door Canopy
A Glass Door Canopy adds a touch of elegance to your doorway. When measuring for a glass door canopy, you need to be extra precise as glass is a more rigid material. The measurements need to be exact to ensure a proper fit and to prevent any stress on the glass panels during installation.
Door Canopy Metal
Door Canopy Metal awnings are known for their durability. When measuring for a metal door canopy, consider the thickness of the metal frame. This may require a slightly larger mounting area compared to other materials. Also, make sure that the wall can support the weight of the metal awning.
Finalizing Your Measurements
Once you have taken all the necessary measurements and considered the style of the awning, double - check your numbers. It's a good idea to measure again to confirm accuracy.
