What is the Standard Width of a Door?
Understanding Standard Door Dimensions
The standard width for interior doors typically ranges from 30 to 32 inches, while exterior doors are usually 36 inches wide. These dimensions have become the norm because they balance ease of use, space efficiency, and structural integrity. A 30-inch door, for example, is wide enough to accommodate most furniture and appliances, making it a practical choice for interior spaces.
Differences Between Interior and Exterior Doors
Interior and exterior doors differ in width due to their distinct purposes. Exterior doors are often wider (36 inches) to enhance security, insulation, and the ability to move larger items in and out of the home. Interior doors, on the other hand, are slightly narrower (30-32 inches) to save space while still providing adequate access to rooms.
Factors Influencing Door Width
Architectural Style and Building Codes
Architectural styles and building codes significantly impact door width choices. Modern designs might favor wider doors for an open, airy feel, while traditional homes may stick to standard sizes. Additionally, building codes, particularly those related to accessibility (like ADA compliance), often dictate minimum door widths to ensure inclusivity.
Purpose of the Door
The function of a door also determines its width. Bedroom doors are typically 30-32 inches, while bathroom and closet doors can be narrower, around 24-28 inches. Special cases, like double doors or sliding doors, may require wider openings to accommodate their design and functionality.
Room Size and Traffic Flow
The size of a room and the expected traffic flow are critical considerations. Larger rooms or high-traffic areas, such as living rooms or entryways, often benefit from wider doors to improve movement and accessibility.
Common Door Widths by Type
Interior Doors
- Bedroom doors: 30-32 inches

Narrower doors are ideal for small spaces, ensuring they don’t overwhelm the room while still providing functionality.
Exterior Doors
- Front doors: 36 inches

- Patio doors: 60-72 inches (for sliding or French doors)
Wider exterior doors are often used for grand entrances or to meet accessibility needs.
Specialty Doors
Specialty doors, such as French doors, sliding doors, and pocket doors, come in unique widths. French doors are typically 30-36 inches per panel, while sliding doors can span up to 72 inches or more, making them ideal for large openings.

Choosing the Right Door Width for Your Needs
Accessibility Considerations
Wider doors are essential for accessibility, especially for wheelchair users or those with mobility aids. ADA guidelines recommend a minimum door width of 32 inches to ensure ease of access.
