How to Measure Your Garage Door



Measuring a garage door can be quite a task if not done properly. They are usually required to be measured before the installation process or when you need a garage door replacement. Garage doors, just like any other doors of your house, are measured through the casing present around them.


To accurately measure a garage door, you need to take the measurements on the inside of the door, which includes the door opening, the headroom, the back room, and the side room.


Measure Garage Door: Installation Guide


Here is a small guide that will help you measure the garage door through a few fairly easy steps:


  1. Measure the height and width of the widest point of the garage door opening, which is the distance between the left side and right side of the same. Make sure to omit any door jambs or deformities in your measurements. These measurements will help you determine the size of the garage door that you will need to buy.

  2. To ensure that there is ample space to fit the vertical portion of the garage door, you need to measure the side room of the door next. These measurements are done from the outside of the door jamb to the wall on which the garage door will be mounted.

  3. The next step is to measure the space that runs between the top of the garage door opening to the ceiling or the lowest obstruction on the ceiling. This is known as the headroom measurements and is essential while measuring your garage door for installation or replacement. The headroom measurements usually differ according to the material of the door required.

  4. The last step is to measure the depth of the garage. This is known as the backroom measurement. It essentially requires you to measure along with the ceiling that runs between the garage door opening to the farthest point of the garage’s rear or the closest obstruction.


Garage Door Measuring Tips to Keep in Mind


- While measuring the door, make sure the jambs and other irregularities are taken into account.

- If you are unable to take the proper door measurements yourself, make sure to seek professional help for accurate dimensions and to save yourself from further troubles.

- The garage door measurements are usually of the same standard size but may differ according to the type of garage door you are willing to install.

- While taking the measurements, ensure that it is in accordance with the door’s material that you wish to replace your previous door with. The standard size for different types of doors may vary according to the thickness of the material.
