How to Measure a Garage Door

how to measure a garage door

Knowing the measurements of your garage helps you shop for a brand-new one. Here are five easy steps to learn how to measure for a garage door and help you get the cost estimates you need from a local garage door company.

1. Measure the Width of the Door

First, measure the width of the garage door’s opening at its widest point. This should be the distance between the right and left sides of the garage door. The width of the opening is the same as the width of the garage door (the door should be framed by 2″ x 6″ wood jambs).

2. Measure the Height of the Door

Second, measure the height of the door at its highest point. Here is the distance between the top of the garage door opening and the floor. The height of the garage door opening is the same as the height of the garage door.

3. Measure the Sides 

Third, measure the width of the sides next to the opening on both the right-hand and the left-hand side. They will need to each measure at least 3-3 ½” wide to fit a vertical track.

4. Measure the Top of the Opening to the Ceiling

Next, measure the height between the top of the opening to the ceiling. This space is called the ‘headroom’ and determines what style of garage door can fit. 15″ of headroom is required for a carriage house door, while all other garage doors require 12″ of headroom. An additional 3″ is needed to install a garage door opener. If your headroom does not meet these requirements, special hardware will be required.

5. Measure the Front of the Opening to the Back of Garage

Finally, measure the space from the opening or front of the garage to the back of the garage. This is called the ‘backroom’. This will be important during installation, especially if installing an automatic opener.
