Standard window sizes in Australia
If you are going to build your own home, or if you have bought a flat that needs renovating and primarily replacing old windows with new ones, you need to understand what double glazed window sizes are appropriate for your project. This is important because there is a typology of window opening sizes for each room: for bathrooms, for living rooms, for bedrooms, for rooms located on attic floors and so on. Ordering windows directly from the manufacturer eliminates the possibility of making a mistake or being cheated. In this overview you will learn:
- Which window sizes are considered standard?
- Why do you save time and money by choosing windows made to standard sizes?
- What are the advantages of standard sized windows?
- How to calculate the window size depending on the application of the room.
Impracticality to go beyond the standard window sizes
There are occasions when a non-standard solution is required for a project and this is a problem that can be solved. However, such cases are very rare when it comes to an art object, for example. You can use an imagination and skills of the window designers and fabricators to create a fitting piece that will cost a lot of money and take a lot of time. Why is this the case? The thing is that production and equipment are working in accordance with set patterns, producing not only accessories, profiles, glass panes of standard sizes according to particular configuration of windows, but also functionally important details and elements for windows. This includes soft covers, reinforced foils and fitting mechanisms, which are in turn manufactured in another facility. In addition, the production of profiles is also a fine-tuned process in which the range of installation widths, heights, reinforcement densities according to the first two parameters and so on are already defined. These processes are computerised and carried out automatically under the supervision of specialists. If it is necessary to produce windows with dimensions that go far beyond the standard ones, it becomes necessary to call up additional resources, which has an impact on the order budget and the production time frame. Here the production algorithm is completely different.
What is the ideal window size for your house?

Based on which parameters the window sizes are calculated
Standard sizes are determined for three types of windows: single, double and triple and more casement windows. According to building regulations, all values are calculated using universal formulas. Today’s plastic window technology allows any size of window construction, as long as the proportions are not distorted. Dimensions of plastic windows in private homes do not differ much from the established norms and are determined by the same national standards. The biggest windows shall be placed in living room, children’s room and bedroom. Smaller windows are suitable for non-residential rooms (kitchen, bathroom, utility room, etc.).
In this way it is possible to find out how exactly the window area and the size of the room to be illuminated should relate to each other, i.e. how many windows and what size are required per room.
When installing double-glazed windows with non-standard dimensions, a number of restrictions must be taken into account:
- A blind window cannot be larger than 6 m²;
- For a window with opening parts, the maximum height is 2200 mm;
- The minimum possible dimensions for a fixed window are 300×400 mm, and for casement windows – 400×500 mm.
The standard window dimensions in a private home depend on the size of the room. For example, for a bedroom or children’s room of 10-12 m2, one 900x900m window will do, but for a room twice or three times as large, the number of openings should be increased.
Window sizes in a brick or wooden house depend on the ownership of the room and are calculated based on the height from the floor:
- in bathrooms and toilets – from 1,300 mm;
- in the kitchen – from 900 mm;
- in living rooms – about 800 mm;
- in attic – about 1000 mm.
Plastic windows from PrestigePlus
Nowadays, it is not a problem to buy inexpensive plastic windows for country houses, because most of them have standard sizes, and the production of such windows has long been mass-produced. The standardisation of window openings is designed primarily to regulate the intensity of light in a room. The gradation in aperture parameters depends on the purpose of the room. Plastic windows can satisfy almost any engineering concept. It is easy to fit into the norm with these windows. Even if you take into account the calculated value, very roughly, that uPVC windows should be about 2/3 of the floor area, this condition is easily met.
Our website has an online calculator where you can pre-calculate the cost of the window by entering the required parameters in the fields. You can also visit our showroom and speak to a manager about any questions you may have.
