In this article, Grandsea will take you through the standard window sizes and provide you with some practical advice to help you choose the ideal windows and doors.
What are the standard window sizes?
Casement or Hinged Window Sizes: These windows combine simplicity and elegance. The standard size of single-pane windows varies, but they are usually 60-70 cm wide x 120 cm high or 70 cm wide x 140 cm high;
Single-hung and double-hung window sizes: Double-hung windows are versatile and have larger openings. The standard sizes for this type of window range from 90cm to 120cm high, with variations like 110cm x 150cm, 120cm x 130cm, 120cm x 140cm, etc.
French Door and French Window Sizes: French doors are ideal if you want a larger opening. Single French doors come in 90cm x 255cm, and double French doors come in 120cm x 245cm.
Window Width
As far as window width is concerned, standard windows can vary between 600 and 1200mm. Again, the width depends on the specific needs of the room and the amount of natural light required. It is important to consider not only the size of the window, but also the aesthetic aspect: larger windows can create a more pleasing visual effect.
Window Height
As for window height, standard windows can vary between 900 and 1200mm in height. When measuring, take into account the space required to ensure adequate lighting and ventilation in the room. However, keep in mind that the height can be adjusted to your preference or specific building requirements, and window brands can also offer windows of different heights.
Other factors that affect standard window sizes
What size windows should I install? You can find windows with different types of opening and closing in the product catalogs of window brands. The most common options are casement, silding and tilt & turn openings. Casement windows are the traditional variants of windows that open inwards or outwards. On the other hand, tilt-and-turn windows feature an outward opening with hinges on the upper part of the window. This option is particularly suitable for areas with limited outdoor space;
It is also important to consider the material of the window. Standard windows can be made from a variety of materials, including wood, aluminum and UPVC windows. Each of these materials has different advantages and disadvantages. Therefore, it is important to make an informed choice based on your insulation, weathering and maintenance requirements.

How to measure window size?
A very practical and useful topic is: how to measure window size correctly. If you are thinking of replacing or installing new windows, it is important to know the correct size to ensure a perfect fit to the wall.
- Make sure you have the necessary tools: a tape measure and a pencil are enough. Before you start measuring, clean the window opening thoroughly so that the edges and details can be clearly seen;
- Measure the height of the window. Place the tape measure vertically along one side of the window, starting from the windowsill to the top lintel. Make sure the tape measure is straight and parallel to the window frame to get an accurate measurement. Write down the measurements
- Now let’s move on to the width of the window. Measure the width of the frame horizontally from one side to the other. Be sure to account for the side frames if you have any. This will be your horizontal measurement;
- For more precision, you can measure a second width in the center of the frame, measuring slightly higher than the first. This will give you a more accurate idea of the size and account for any deviations in the frame.
- If you plan to replace the window sashes as well, it’s important to measure them as well. Measure the height and width of each door. If you have multiple doors, be sure to measure these individually.
Once you have your measurements, you can purchase new standard-size windows or contact a reliable window and door company for custom-made ones.
Window Size: What is the minimum size a window must have?
Window sizes can vary greatly depending on your personal needs and architectural style, but there are some general guidelines you should follow. Generally speaking, a window should be large enough to provide ample natural light and ventilation into the room.
As for the minimum size of a window, the width of a window should be at least one-tenth of the floor area of the room it is located in. For example, if you have a 20-square-meter room, the width of the window should be at least 2 meters. This ensures adequate light flow and also allows for easy evacuation in an emergency.
Window height should be high enough to provide a pleasant view of the outside and let in fresh air. The minimum height generally recommended is 10% of the ceiling height. So if the ceiling is 3 meters high, the window height should be at least 0.3 meters.
In addition to the minimum size, it is also important to consider the shape of the window. Traditional casement windows are a popular choice, but you can also choose bifold windows, tilt windows or sliding windows. The choice of shape depends on your personal taste and the aesthetics of the building.
Dimension of Window relative to Wall Area It is essential that windows be situated so as to cover 10-15 percent of the overall wall surface area for adequate light exposure and an aesthetic look. In general, placing them at this percentage ensures adequate illumination while creating an aesthetic balance in their placement on your walls.
Conclusion on standard window sizes
In summary, the size of the window depends on several factors and can vary according to your personal preferences. It is important to consider the architectural style of the house, the natural lighting required, ventilation needs and the impact of the surrounding environment, such as soundproof windows next to the street. Also remember to consider the type of window material, as it will affect the size and amount of natural light entering the home.
