A Fitter’s Guide to Measuring a Garage Door

Measuring a garage door can be tricky, but whether you’re replacing a garage door or you’re fitting a brand new one, it is important to keep a few things in mind. The key thing to remember is that garage doors require a fixing subframe.  You need to take this into consideration when measuring the dimensions, as subframes can vary from one manufacturer to another.

Now that you’re ready, here’s our step by step process to measuring a garage door:

Measuring a Garage Door

Step 1

Firstly, measure the width of the opening at its widest point. This is a basic measurement but remember to look out for any general irregularities that may obstruct the movement of a new or replacement garage door.

Step 2

Next, measure the height of the garage door from the bottom opening to its highest point. Again, it is important to look for any general irregularities, especially an uneven floor.

Step 3

Manual up and over garage doors will require 4” to 6” each side to be able to open comfortably without colliding with objects. So it is important to measure the space it needs to open and close.

If you’re installing other types of garage doors, such as side-hinged garage doors, the process is quite similar.  However, you will need to also measure the out-swing opening.

Step 4

You need to ensure that there’s enough room for a track to be attached to the ceiling for up and over garage doors. Note the space from door to wall and the top of the door to the ceiling.

Top Tips for Measuring a Garage Door

Garages vary in sizes and layout but here are some top tips to ensure you’re fitting the correct garage door for your space:

• Note any light fixtures that could get in the way
• Make sure anything on the walls is not going to obstruct the garage door and its hinges (shelves, pipes, etc)
• Make sure you’re not rushing. A standard up and over garage door can take around two hours to install (excluding measuring time)
• Make sure you consider the security (if there are added security locks, consider how you will install these)
