Garage Door Clearance Requirements

Building a garage door requires skills and attention to recommended configurations in various aspects. Before replacing the existing or building a new garage door, beware of the minimum requirements while planning. All clearance involved during garage door installation will prevent obstructions and maximize the usage as well as improve performance. In most cases, you will find measuring and planning is done based on a tight budget; hence, significant limitations are preferred during the installation despite prior warnings. This might lead to fault constructions. The following are major garage door clearance requirements.

Headroom Clearance

Perhaps you are asking yourself how much headroom is needed for a garage door? Well, there is a need to plan and measure the headroom right above the garage door before you order or install overhead openers. Take measurements from the frame of the garage door to the nearest obstruction using a tape measure. Ensure that you account for all the blockages that are just above the opening curve of your garage door to allow it to move smoothly. Whether it is commercial or residential, be sure to account for additional space based on your door size, weight, and other options that may affect the headroom.

Side-Room Clearance

The side-room of your garage door include the left and right space of the opening. Side-room clearance will vary based on various situations like the location of the garage door, the thickness of the tracks as well as the condition of the adjacent walls. When clearing the side-rooms, you need to pay attention because the brackets for the horizontal rails and the opening meet here. Also, you should beware that the torsion springs require space on each end of the bar, usually about 3.75 inches. Therefore, you need to ensure you have accurate measurements to prevent the garage door from obstructions when opening or closing.

Backroom Clearance

Backroom describes the room right from the opening towards the rear of the garage door. Backroom clearance will involve eliminating the obstruction that may interfere with the opening and closing of the door. When installing a garage door, have in mind that it needs to roll completely when you open it. Be sure to secure enough space that is slightly longer than the measurement of the door. When measuring the backroom, keep in mind the extension installed behind the garage door, such as the openers to ensure that they fit without causing disturbance to items in the garage.


When you are looking to create room for your garage door, you need to have the above clearance requirements in your mind. Whether it is a residential or commercial, ensure you have accurate measurements before initiating any clearance. Some garage doors may be easy to install while having the clearance requirements in mind; others require experts to ensure the door is suitable for your garage. Determine your garage situation to know what exactly you need to clear. You will be happy to have an organized garage with enough space. You can also create room to install your floor-mounted stool in the garage.
