Choosing The Right Garage Door Size for You

Before choosing a garage door size, we recommend measuring the dimensions of your garage taking into consideration: 


  • Height and width of door opening to make sure that the garage door that you are installing is the correct size. 
  • Headroom is essential, particularly for garage doors with larger motors and mechanisms. Knowing the amount of headroom available can help you select which option is right for you.
  • Garage Depth is important to know so that you can assess how long the tracks for your garage door can be. 
  • Side Room is essential for the structural support of your garage. Single garages should have a minimum of 100mm on each side and double garages needing 250mm. 


While measuring the size of your garage, consider the way that you are planning to use any space in your garage for storage, workbenches etc and how this may impact your choice of garage door.  


Single Garage Door Sizes

Size: The Australian standard sizing for single garage doors is 2100mm high x 2400mm wide.


Consideration: It should be big enough to comfortably allow your vehicle to easily get in and out of your garage. If you drive a large 4x4 or SUV, you may want to consider a wide option for better accessibility. 


Double Garage Door Sizes

Size: The standard size of a double garage door in Australia is 2100mm high x 4800mm wide. 


Consideration: When choosing a double garage door, it is important to consider the space for installation. This means taking into account at least 120mm of side room from the garage to the corner of your house or shed and approximately 300mm of space at the top of your garage to allow for the installation of a motor.
