Standard Door Size

A door is an opening in a building, wall, or fence that allows entrance to or exit from a room, building, or enclosure. Doors have different sizes, shapes, types and functions.

A door is either fixed or hinged so that it can swing open for use. Usually, a door has hinges on one side and some sort of latch on the other, but not always, especially older doors have latches that are used to keep the door closed, while hinges are only used to keep it in a closed position.

Door shapes vary depending on the building style and region where there are doors installed. Doors can be made of many materials like wood, metal, fibreglass, glass etc. In spite of the material that is used to construct a door, there are some common construction components.

There are many types of doors to choose from, such as panel doors, flush doors, standard timber doors, glass doors and many custom doors and products with each with a different door thickness. If you’re looking for something fancy with good door thickness go for flush doors, a bifold door or good and strong quality glass doors.

Standard Door Size Australia

Door sizes in Australia vary. The average size of the door is around 2040 mm x 820 mm x 35 mm. That is height, width, door thickness.

It majorly depends on the width of the opening required when erecting a doorway between rooms or walls. Since there are numberless types of doors available, it also depends on the type of opening that is to be fitted with a door.

Door Sizes Australia

Standard door size calculation is based on the width of the opening. Sometimes, there are also other factors like ceiling height, wall thickness etc. that are considered while sizing a door.

Generally, a rough estimate of a standard door size in Australia is up to 2040 mm high and 820 mm wide. The thickness varies between 18 mm to 35 mm which makes it difficult to be measured in an accurate way.

However, note that if you want an exterior or garage door, the height may vary from 2000mm to 2400mm and width from 850mm to 950mm accordingly. Also, there needs to be some allowance for carpentry because most doors are not installed flush with the frame but leave a gap of about 3 mm for expansion purposes. That’s why it is recommended to make the opening 10 mm bigger than what you finally need.

There are many factors that affect the size of a door.

Basically, to make things easy there are some standard sizes that you can go with or simply ask for an estimate and most door manufacturers may be more than happy to help you out. The choices vary from size and design as well as price range and budgets.

As mentioned earlier it all depends on your requirements and budget as well as whether your door is going outside or inside the house.

If your door is going outside, make sure it has a heavy-duty frame to keep the weather out. Don’t compromise on quality when it comes to an exterior doors because they are supposed to be stronger and more durable than interior ones. Even if you’re looking for an internal door, you’ll need certain specs like fire rating etc.

If you’re looking for a standard size then talk about width first before height because most people decide the height depending on whether they want the door to fill up the entire wall or not. So it’s better that you decide about the width first so that things can be easily figured out thereafter.

Inner Frame Height

The height of an inner frame including top, bottom and side(jamb) rails could measure around 155mm to 165mm. This value can also vary depending on your specific requirements. For instance, if you are looking for a fire-resistant industrial-grade steel framed door then it may be at least 203mm high because industrial doors are required to have heat insulation or protection up to 750 degrees Celsius. You may even need other special features like advanced locking systems etc which could affect the overall cost as well as dimensions accordingly.

Width of Door Frame

It’s possible that you may need different widths for different parts of your door frame. For instance, in case you are looking for a heavy-duty industrial door then the best width is around 235mm while for other uses normal width can be anywhere between 195-210mm.

Similar to the widths of door frames, you may need different widths for different sections of a single door as well. The standard widths are 800mm for an internal door and 760mm/845mm(H) for an exterior door. Again, if there are any special requirements regarding width then you can always discuss with the supplier to get their expert opinion.

Standard Door Frame Sizes – Exterior

The standard length of an exterior door frame is 375 mm. But this value may vary depending on your needs as well as the type of frame. For instance, some commercial-grade frameless or panel doors have a height anywhere between 1220mm to 1815mm which would ultimately increase the overall size depending on the height. Similarly, commercial doors have different widths ranging from 600mm to 1100mm which can also affect the final size greatly. Each type of door has a different frame size. This covers a bifold door, glass doors, flush doors and even panel doors.

Height is one of the most significant parameters when it comes to doors in Australia. The standard height for an exterior or interior door lining is in the range of 1815mm-1830mm, but this can also vary depending on your requirements(if any).

It’s even possible that you may get different heights for different parts of the same door like top and bottom hinges etc.

For standard door widths in Australia, common measurements are 795 mm and 860 mm for interior doors and 760/845/900/1220 for exterior doors(in order of preference).

Standard Internal Door Width Australia

Standard door sizes for hidden door hinges range from 595 mm (H) x 285 mm (W) and 635mm (H) x 295mm (W). These dimensions can also vary depending on the type of door and your requirements. For example, if you’re looking for an internal sliding door then it is better if thickness measures around 18-20mm so that it can handle heavy usage with ease.

The distance between the horizontal lines that are drawn from one edge of a door to another edge with or without an additional overhead lintel is known as the width of a door. The standard size for this distance is 600 mm.

In Australia, most doors are made from lightweight timber using plywood construction. This saves a lot of cost and time when working with heavy materials in a hot climate. Plywood is not used in commercial-grade doors because it does not last long in humid environmental conditions such as those found in coastal cities like Perth. It also depends on the type of material you plan to have on your door. Commercial-grade doors use solid timbers that are treated properly to prevent damage from termites and other pests.
