How Do You Measure The Opening For A New Garage Door?

5 Steps to Measure For A Garage Door

When you ready to get a new replacement garage door installed at your home, Maybe you`re putting in a new door for the first time. The first step in purchasing a new garage door is to figure out what size door you need. It`s extremely important that this measurement is correct in order to ensure a seamless installation. You may think a quick measurement of the door or opening`s height and width is enough, but there are a few other measurements you will need to take in order to properly measure your garage door. All you need to begin the measurement process is a tape measure. In the video below, our Overhead Garage Door Technician, George, walks you through the process of measuring the opening for a new garage door. We have outlined the steps below as well.

First, measure the width of the door. This is the distance between the left and right sides of the finished opening. You`ll want to make sure you take the measurement at the door`s widest point, in feet and inches.

Next, measure the height of the door. You`ll also take this measurement at the door`s highest point, from floor to the top of the finished opening. It`s important that you take this measurement in three spots: left, center, and right sides of the door. If one side of your opening is sagging – it can cause several issues with the garage door installation.

Measure the width of the area next to the openings, 4-4.5cm is required on each side for installation of the vertical track.

After that, you`ll need to measure the distance from the top of the opening to the ceiling. This is called the headroom. You`ll measure from the header to the lowest point is at least 30cm( single track) or 20cm (double track) to ensure you have enough clearance for your torsion system and the opener together.

Measure the distance from the opening to the rear of the garage. This is called the backroom.
