When it comes to interior design, one of the essential elements to consider is the width of interior doors. The width of a door can greatly impact the functionality, aesthetics, and accessibility of a space. In this article, we will explore the standard width of interior doors in 2023, providing you with valuable information for your next home improvement project.

Understanding Standard Door Sizes

Standard door sizes can vary depending on the region and the purpose of the door. However, in 2023, the most common width for interior doors remains around 32 inches (81 cm). This width allows for easy passage and is suitable for most residential applications.

Factors Influencing Door Width

While 32 inches is the standard width, certain factors can influence the decision to deviate from this size. These factors include the architectural style of the home, the size of the room, and the specific needs of the occupants.

Architectural Style and Door Width

Architectural styles often dictate the width of interior doors. For example, in older homes with narrower hallways, the doors may have a width of 28 inches (71 cm) to maintain the historical integrity of the property. On the other hand, modern and open-concept homes may opt for wider doors, such as 36 inches (91 cm), to create a sense of spaciousness.

Room Size and Door Width

The size of the room is another important consideration when determining door width. In smaller rooms, narrower doors can help maximize the available space. However, in larger rooms or rooms with high traffic, wider doors can enhance accessibility and ease of movement.

Accessibility and Universal Design

In recent years, there has been a growing emphasis on accessibility and universal design. As a result, wider doors, typically around 36 inches (91 cm), have become more popular. These wider doors can accommodate individuals with mobility aids, such as wheelchairs or walkers, allowing for greater independence and freedom of movement.

Custom Door Widths

While standard door widths are common, custom door sizes are also available for those seeking a unique or non-standard look. Custom door widths can be tailored to fit specific architectural designs, personal preferences, or unconventional spaces.


Choosing the right width for your interior doors is crucial for both functionality and aesthetics. In 2023, the standard width for interior doors remains around 32 inches (81 cm), but various factors can influence this decision. Consider the architectural style, room size, and accessibility needs when determining the ideal door width for your home. Remember, custom sizes are also an option if you want to create a personalized touch. With this knowledge, you can confidently select the perfect interior door width for your next renovation project.
