How to Measure Your Garage Door and Its Components

Choosing a garage door is a process that requires that you have accurate measurements before you proceed. This applies to whether you are getting a garage door for the first time, or you are replacing your existing one.

It's more than just measuring the width and height that you need. The information below should be a perfect guide to get you through the process.

How to Measure Your Garage Door?

This section is all about gathering all the measurements that are important to your garage door opening. Getting precise numbers for the various areas that surround your garage door is essential as you don't want your new or replacement garage door to not fit.

You can also take this time to inspect the areas being measured for any defects or compromises to their integrity. It would be in your best interest to perform these measurements before any installation begins.

Step 1: Measure Width of the Garage Door

The first thing you need to do is to measure the width of the garage door by using the widest point present. This refers to the full measurement from the left to the right side of a finished opening.

Step 2: Measure Height of the Garage Door

Once you have completed the width, then the height is next. Look for the highest point of the opening, as you need to complete your measurement from there to the floor.

This is a perfect time for you to identify any garage door opening irregularities, such as an uneven frame or an uneven floor.

Step 3: Measure Side Room

Your garage door side room refers to the areas that sit to the left and right of the opening. For the installation of a vertical garage door track, there are specific measurements that may be required. It is likely that the required number ranges anywhere from three to five inches.

The requirement for this step means measuring the width of the side room at both sides of the garage door opening. You should note that the inside of the garage door is required to be framed with wood.

Step 4: Measure Headroom

Like the side room, the headroom speaks to the area that runs from your ceiling to the top of the garage door opening. The idea is to capture the measurement from the highest point of the ceiling to the lowest point of the opening's top.

Note that there should be no less than six inches of space between the lowest point and the header. This is to ensure that your torsion system and opener have the required clearance for their installation.

Step 5: Measure Your Garage Room

The requirement here is that your measurement should run from the top of the opening to the rear of your garage. Ensure that you capture your measurements from the furthest point of the opening stop to the furthest point of the backroom.

How to Measure Garage Door Springs

This section deals with the measuring of garage door springs, such as torsion springs and extension springs. Completing the measurements here are necessary, as they provide you with the information that you need on what length you should be looking to purchase.

Unfortunately, it's more than just measuring springs from one side to the other. This is because springs are coiled, but the measurement that you need is the unwound length.

Whether the spring is still wound, or it is broken and unwound, you still need to capture the measurement accurately. Never unwind the spring yourself, as you could compromise your own safety and that of others.

How to Measure Torsion Springs?

The measurement of your torsion springs requires a four-step process, which is as follows:

1. Collect the measurements of the wire size. Measuring this requires getting the length off 10 coils that are in the spring. Your 10-coil count may measure 2½ inches. If so, then your wire size is 0.25 inches. Similarly, if the 10 coil count measures 1¼ inches, then you have a wire size of 0.125 inches.

2. The inside diameter is the next item on the agenda. A two-inch diameter is the most common measurement on the market. In fact, nine out of every 10 garage doors in the United States of America have such a size.

However, you still need to do this just in case yours doesn't. All you need to do is capture the diameter's interior with your tape measure.

3. Your spring length comes next. This measurement should be captured when the spring is closed. Should it be a broken spring, you must close any gap in the pieces before you begin to measure.

4. The spring's wind direction is the final piece of the puzzle. You can ascertain this by using the paint on the end of the spring or the position of the spring. If there is still paint on the spring and it is red, then you have all right-wound spring. If the paint is another color, then you have a left-wound spring.

The possibility exists that the paint is no longer visible. In such cases, you can use the location of the spring to provide the information you need. If the spring is one that is on the right side of the door, it is left wounded. Similarly, if it is on the left side of the door, then it is right wounded.

How to Measure Extension Springs?

There is a three-step process associated with getting the required measurements of your extension springs.

1. First, you must measure the length of the spring. Just like the torsion springs, the length that you need to capture for your extension springs is the unwound one.

2. Second, the diameter of the spring is needed. This is the internal diameter, so you need only grab your tape measure and check what the number is on the inside.

3. Finally, capture the length of the coil of the spring.

Note, however, that with any spring, you also have the option of calling a professional garage door repair company to assist you with your measurements.

Measurements for Your Garage Door Track

For a smooth installation, you need to know the type of garage door track that you need. This involves appropriate measurements that can make the whole installation process easier.

It's essential that the tracks on both sides are the same type and size. Here are some track options and their associated measurements:

1. For a standard lift rack with torsion springs, your measurement should be from the top of the opening to the ceiling. If there is any obstruction before getting to the ceiling, then your measurement should end there. For a track with a 12-inch radius, you need 13 inches of headroom, while a 15-inch radius tracker requires 16 inches of headroom. A further three inches is necessary if you intend to use an electric motor.

2. If using a low headroom double track, you need 10 inches of headroom with no motor and 13 inches of headroom with a motor.

3. There is also the low headroom rear torsion option. 6½ inches of headroom is required without a motor, while 9½ inches are needed with a motor.

4. For low headroom extension springs, the measurements are the same as those of the low headroom rear torsion type.
