bedroom window sizes & dimensions

Bedroom windows play a pivotal role in shaping the visual character of the room and dictating its comfort and functionality.

The sizes and dimensions of bedroom windows are not mere technical specifications; it is design choices that harmonize aesthetics with practicality.

Whether you seek to invite abundant natural light, facilitate ventilation, frame captivating views, or simply infuse your bedroom with a touch of architectural elegance, understanding the nuances of bedroom window sizes and dimensions is paramount.

In this article, we delve into choosing the right bedroom window sizes and dimensions for your haven.

Common Bedroom Window Size


Common window sizes for bedrooms refer to the typical or frequently used dimensions for windows in residential bedrooms.

These dimensions are not fixed and can vary based on factors like architectural design, regional building codes, and individual preferences.

However, average window size provides a general guideline for the dimensions of windows you might expect to find in a standard residential bedroom.

  • The normal window size for a bedroom that you can never go wrong with is 24 inches wide and 36 inches high.
  • But if you are looking for the minimum window size, one window must be at least 20 inches wide and has a height of at least 24 inches.

Standard Bedroom Window Sizes

The standard size of windows plays a crucial role in the design and functionality of your home. Windows provide natural light and ventilation and contribute significantly to a structure’s overall aesthetic appeal.

Let us explore the standard window dimensions and types of standard windows, helping you make informed decisions regarding enhancing the comfort, energy efficiency, and visual appeal of your living or working spaces.

1. Single or double hung window


These types of vertical-sliding windows are similar in design but differ in how the window sashes operate.

  • Single-Hung Window – Only the bottom sash (the movable part of the window) can be opened or raised in this window. The top sash is fixed in place and does not move.
  • Double-Hung Window – This window, on the other hand, allows both the top and bottom sashes to move independently. This provides greater flexibility in controlling ventilation and cleaning the window.

These two have the same size, which are following dimensions:

  • Width of window: 24 to 48 inches
  • Window height: 36 to 72 inches.

2. Picture window


A picture window is a non-operable, fixed window designed to frame panoramic views and flood interior spaces with natural light. Their immovable nature makes them ideal for showcasing scenic landscapes and architectural features, elevating residential and commercial spaces with a sense of openness and luminosity.

Picture windows come in different dimensions, with:

  • Common widths: 24 to 96 inches
  • Heights: 12 to 96 inches

3. Sliding window


Sliding windows offer a seamless blend of functionality and style. These horizontally movable windows allow for effortless ventilation and natural light infusion.

Sliding windows enhance bedroom comfort with ease of operation, space-saving qualities, and the opportunity to enjoy gentle breezes or picturesque views while maintaining an uncluttered, modern appearance in the room’s aesthetic.

Typically, standard sliding windows come in the following dimensions:

  • Width range: 36 to 84 inches
  • Height range: 24 to 60 inches

4. Bay window


Bay windows bring an air of elegance and charm to bedroom spaces. Compared to other windows, this is more expensive but a good investment. They extend outward from the room, creating a cozy alcove bathed in natural light.

A typical bay window features a central fixed pane flanked by two angled operable windows, offering both ventilation and unobstructed views.

Standard window dimensions for bay windows vary:

  • Typical widths: 40 to 144 inches
  • Typical heights: 48 to 60 inche

5. Casement window


Casement windows are an excellent choice for bedroom spaces, offering functionality and aesthetic appeal. Hinged on one side, they swing outward to open, allowing optimal ventilation and easy cleaning.

Casement windows also come in various styles, such as single casement or multi-pane configurations, enabling homeowners to customize their design to suit their bedroom’s aesthetic and functional needs.

Standard casement window varies, but you can follow these standard dimensions and match them with your room size:

  •  Typically widths: 17 to 41 inches
  • Heights: 16 up to 33 inches

6. Awning window


Awning windows are a practical and stylish choice for bedroom environments. Hinged at the top, they open outward from the bottom, creating a sheltering effect, allowing fresh air circulation, and maintaining privacy.

These windows are versatile, providing ventilation while shielding against rain and ensuring security. Their combination of functionality and aesthetics makes them an excellent choice for enhancing bedroom comfort and appeal.

The typical window size for awning spans the following ranges:

  • 12 to 96 inches in width
  • 12 to 60 inches in height

Custom Window Sizes


Custom windows for bedrooms offer limitless design possibilities to suit individual preferences and architectural needs. Unlike the typical size, these windows are tailor-made to fit unique spaces and design concepts.

Dimensions for custom bedroom windows can vary significantly, ranging from small decorative features to large, elaborate installations that cover entire walls. Especially for residential window sizes that are made to fit your window’s exact shape and size.

Custom windows empower homeowners to create a distinctive, personalized atmosphere that elevates both the functionality and visual appeal of their private spaces, making them truly one-of-a-kind.


The impact of bedroom window sizes & dimensions, measured meticulously in cm, in mm, and even in feet, transcends mere numbers. They shape the ambiance of a bedroom, harnessing natural light and ventilation to curate an atmosphere of tranquility.

From the standardized dimensions to the bespoke creations that adorn a bedroom with big window, these elements are symbolic of personalized design. The journey through this exploration of bedroom window sizes and dimensions underscores the importance of thoughtful consideration. It ensures that every room is a sanctuary of individuality and style.
