There are so many customisation options for Perth doors that must be considered when choosing new ones for your home. Type, colour, locks, and more are all important for any door, but another element that is pivotal to the overall design is door size.
To some, this may seem like a trivial matter, but it is critical to consider the right size for doors being installed to make sure they fit with the size of an existing or new house. This guide will look at interior vs exterior door sizes, standard door sizes in Australia, and the comparisons between the two.

Are Interior and Exterior Doors Different Sizes?
One of the first points to consider is the difference between the sizes of exterior and interior doors.
Interior doors are generally smaller than exterior doors for a number of reasons. One is that they do not need to accommodate furniture or other large items being brought inside the home. Interior doors also tend to be less sturdy than exterior doors because they are not as exposed to the elements and do not need to provide as much security.
Exterior doors, on the other hand, must be able to withstand strong winds and rain, as well as provide a high level of security. This is why they are typically made from stronger materials such as steel or aluminium and are also usually thicker than interior doors.
Different types of doors such as glass doors, custom doors, bifold doors, flush doors and more can have varying sizes whether they are exterior or interior doors.
Interior Door Sizes
The standard door size in Australia for internal doors is 820mm x 2040mm. The typical ranges of this are 55-85cm for standard door width and 200-215cm for standard door height. However, there is some variation in these measurements depending on different door manufacturers.
If you need an interior door that is narrower than standard interior door sizes, you can get doors that are as narrow as 60cm wide. Most interior doors have a standard door thickness of 35mm.
Exterior Door Sizes
The standard door size in Australia for external doors is 870mm x 2040mm. The typical ranges of this are slightly bigger than interior doors, with 60-95cm in width and 200-225cm in height. Again, there may be some slight variation depending on the manufacturer. If you need an exterior door that is wider than the standard size, you can get doors that are up to 120cm wide.
The standard exterior door thickness is a bit thicker than interior doors at 40mm, however, they can also be 35mm in some configurations such as panel doors or folding doors.
Why Are There Different Door Sizes?
Different-sized doors are required for different purposes. Interior doors do not need to be as strong or secure as exterior doors, so they can be made from lighter materials and don’t need to be as thick. Exterior doors must be able to withstand bad weather and be strong enough within their door frames to deter intruders, so they are made from thicker, stronger materials.
There is also a difference in the standard door size for commercial and residential properties. Commercial doors often need to be wider to accommodate things like wheelchairs or trolleys, whereas residential doors only need to be wide enough for people to comfortably walk through.
