How to Measure Your Garage Door Opening
Before choosing a new garage door, it’s important to measure your garage correctly.
Follow these steps:
1. Measure the Width
Measure the distance between the left and right sides of the garage opening.
2. Measure the Height
Measure from the floor to the top of the opening.
3. Measure the Headroom
Headroom is the space between the top of the opening and the ceiling. Most garage doors require 10″–12″ of headroom.
4. Measure the Side Room
Side room is the space on each side of the opening needed for tracks.
5. Measure the Backroom
Backroom is the distance from the garage opening to the back wall.
Taking these measurements ensures your new door will fit properly and operate smoothly.
