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 one being what size are you going to get? There are numerous factors to take into consideration, although understanding the amount of required side and headroom for the specific type of garage door is an important place to start. Other key considerations include:

  • What is the size of your car?
  • Do you intend to use your garage for storage?

These are vital points to consider in creating your perfect garage that’s ready to store, protect, and preserve what’s important to you. Ensuring you have the required space to fit your desired garage door is certainly something you should put some detailed thought into, as getting it wrong can limit your design options and functionality.

Standard Garage Door Sizes

There is a common misconception that there are only certain sizes available, and that standard size garage doors are available off the shelf. However, in Australia, all doors are made to measure and are available in a variety of sizes.

All garage doors including, roller doorspanel doorssectional doors, and tilt doors are made to measure.

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

Single Garage Door Size:

A standard single garage door is 2100mm high x 2400mm wide.

Double Garage Door Size:

A standard double garage door is 2100mm high x 4800mm wide.

The process of deciding on which type of garage door is going to best suit your garage, carport or shed is based greatly on your needs. You may find that, if you have a large vehicle(s) or a wish for extra storage, you need the maximum opening possible.

Often customers think that the floor to ceiling height of their new garage or carport looks really high, but you then have to take into account that the door itself requires a certain amount of space to be installed and this will impede on your actual opening height once the door is installed.

So it is important to either measure or ask a professional what your opening height will be when the door is in the open position. This ensures that you can fit your vehicles and walk in and out of the space with ease.

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 is increasingly popular to use garage space for storage or as another room in your home. If you’re planning on doing this, you may need something bigger than a single size garage.

Garage Door Thickness

While it may not seem important the thickness of a garage door may be pivotal in reducing sound pollution for houses or businesses located in particularly loud areas. While insulated doors aren’t common in the Australian market, they can be custom ordered if required. A standard garage door is typically 30mm to 51mm thick.

Problems That Affect Garage Door Sizes

When renovating an existing house, most people are limited to the original size of the garage, unless they are 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 also opting to excavate under the house to give more height by building a carport underneath or at the front of the house.

There are other factors to be aware of that can reduce the height of a garage door installation if the wrong type of door is chosen for your property. The factors that can restrict the height of your garage include:

  • Structural beams
  • Structural posts
  • Plumbing
  • Pipe-work
  • Electrical conduit
  • Shelving units

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.
