Garage Door Sizes

  • Published on May 26, 2015

Thinking about getting a new garage door, but don’t really know where to start? Installing a garage door comes with a lot of decisions. The main decision is what size are you going to get. There are numerous factors which will influence what size you can get installed in your home. The first thing to know is what sizes are available.

All garage doors including roller doors, panel doors, sectional doors and tilt doors are made to measure.

There is a common misconception that there are only certain sizes available and that standard size doors are available off the shelf. However, all doors are made to measure and are available in a variety of sizes. Standard garage doors range in size from as low as you want to go all the way up to 5 metres high and from 1 metre wide up to 6 metres wide.


In the new home market, there are standard garage door opening sizes that builders generally follow. Sizes include:

  • Single size: 2100mm high x 2400mm wide
  • Double size: 2100mm high x 4800mm wide
  • Custom: 2400mm high X 5200mm – perfect for wide for larger vehicles

If you’re considering getting a new garage door, it’s important to consider what size you want and why. How many cars do you own, or are planning to own? What is the size of the vehicles? If you’re planning on having more than one vehicle, or in a growing family, it may be better to consider a double size garage door, rather than limiting yourself to a single size.

It’s also important to not only think about the size and quantity of your cars, but what else you’re going to be using the garage for. It’s popular to use garage space for storage. If you’re planning on doing this, you may need something bigger than a single size garage.

Problems that affect garage door sizes

When renovating an existing house, most people are limited to the original size of the garage, unless undertaking structural work. Many older homes in Brisbane, such as the iconic Queenslander, are generally limited for height under the house. These types of houses benefit from installing tilt doors as these often give the best height clearance. Many people are opting to excavate under the house to give more height and build in underneath or build a carport at the front of the house.

There are other factors that can reduce the height of a garage door installation if the wrong type of door is chosen. There are factors that can restrict height, such as:

  • Beams
  • Plumbing
  • Pipe work
  • Electrical conduit
  • Shelving
  • Posts

When installing a garage door, make sure to keep these factors in mind so you do not encounter any problems.

How to measure a garage door

Want to find out how big your existing garage door is? If you’re after a custom-made design, you’re going to want to get the dimensions right. Using a tape measure:

  • Measure the width of your garage door, from measuring from one side of the door to the other.
  • Measure the height by measuring from the floor to the top of the garage door. Make sure to check if your garage door has any strips attached to the bottom that will account for extra height.
  • Make sure you leave room to run the tracks. Measure the space between the side of the door and the wall on both sides. This space should be at least 100mm, which most garages have, or 250mm for double garages.
  • If you’re planning on installing sectional or tilt garage doors, you’ll need to ensure you have roof storage space. To know if you have enough space, measure from the garage door frame to the back of the garage.
