How To Measure For Garage Door

If you're planning to replace your garage door, the first step is to accurately measure the opening. This ensures that the new door will fit properly and operate smoothly. Here's a step-by-step guide on how to measure for a garage door:

1. Determine the Garage Door Opening Type

There are two main types of garage door openings: rectangular and arched. Rectangular openings are the most common, while arched openings are typically found on older homes. Determine the type of opening you have, as it will affect the measurement process.

2. Measure the Opening Width

Measure the width of the garage door opening at its widest point. This is typically at the header, the top of the opening. Use a measuring tape or laser level to get the most accurate measurement. Record the width in inches.

3. Measure the Opening Height

Measure the height of the garage door opening from the header to the floor. Make sure to measure to the finished floor level, not the subfloor. Record the height in inches.

4. Measure the Backroom Depth

The backroom depth is the distance from the back of the garage door opening to the wall behind it. This measurement is important if you're installing a new door with an opener, as it determines the length of the track and the opener arm.

5. Measure the Side Room

The side room is the distance from the edge of the garage door opening to the nearest wall or obstruction on either side. This measurement ensures that there's enough space for the door to fully open without hitting anything.

6. Note Any Obstructions

Make note of any obstructions within the garage door opening, such as windows, light fixtures, or pipes. These obstructions may affect the size or placement of the new door.

7. Double-Check Measurements

Once you've taken all the necessary measurements, double-check them to ensure accuracy. Small errors can lead to problems with the installation or operation of the new door.

Additional Tips for Measuring

Use a professional-grade measuring tape or laser level for the most accurate results.
Have a helper assist you with the measurements to ensure accuracy.
Measure the opening multiple times and take the average to minimize errors.
Provide the measurements to the garage door supplier or installer for verification and order placement.

By following these steps, you can accurately measure for a garage door and ensure a proper fit and smooth operation. If you encounter any difficulties or have concerns, it's recommended to consult with a professional garage door installer for assistance.
