Standard Door Sizes In Australia

10 Jan 2019

Your doors are one of the first things any visitors will see when they come to your home. While doors serve a function, ensuring privacy and blocking out sound, they can also add character and style to any property.

While there’s an array of choice, material and colours to choose from, Australian doors are sold in standard sizes. If you’re trying to fit your house out with new doors, then the cheapest way would be to buy ones which are ready made for installation.

These types of doors are cheaper than custom doors which are tailor-made to suit your specific requirements.

Standard Internal door Sizes

Internal doors are less thick than external ones. There are two styles of internal doors panel and flush.

The most affordable type of internal door is a panel door, which is usually made of wood and has an inlaid panel and is more traditional. Panel doors offer good sound insulation and are made with either solid wood or a hollow body.

Flush doors include a core of solid material, usually laminated timber or plywood, and can be easily painted as they are smoother. Because they have no panels, they’re easier to clean. Their sleek finish means they fit in well with modern décor and tend to be less expensive than panelled doors.

In Australia, the most common internal standard door for both panel and flush has a height of 2040mm, a width of 820mm with a thickness of 35mm.

While this is the most common standard door size, there are other sizes which are popular and also deemed standard size and these are:

2040mm X 620mm X 35mm
2040mm X 720mm X 35mm
2040mm x 770mm X 35mm
2040mm X 870mm X 35mm
2040mm X 920mm X 35mm

What to consider

Doors for toilets and dressers are generally smaller in width. If you want your house accessible to all, then you’ll need doors which can accommodate wheelchair access so you’ll need them slightly wider.

While the height of a standard door in Australia is 2040mm, some newer homes are being built with taller ceilings to create that feeling of space. If you have high ceilings you could consider marginally taller doors which reach 2340mm.

There are set guidelines or Australian Standards for the height of the door hardware. It should be within 900mm and 1100mm above the floor – that’s around waist height for the average adult.

Standard External Door Sizes

External doors are also standardised to help homeowners and they are slightly thicker in depth coming in at 40mm as they are sturdier. The most popular is a height of 2040mm X 820mm with a thickness of 40mm.

Other sizes include:

  • 2040mm X 620mm X 40mm
  • 2040mm X 720mm X 40mm
  • 2040mm x 770mm X 40mm
  • 2040mm X 870mm X 40mm
  • 2040mm X 920mm X 40mm
