By Melissa SmithJanuary 10, 2026

When it comes to the width of doorways, the measurement can vary greatly depending on the type of door, the room it's in, and the building's architecture. But why do we care about doorway widths? Understanding this dimension is crucial for accessibility, furniture placement, and overall functionality of a space.

Doorways, like many aspects of construction, are governed by building codes and standards. These regulations ensure safety, accessibility, and structural integrity. So, let's delve into the world of doorway widths, exploring the standards, the variations, and the reasons behind these measurements.

Standard Doorway Widths

In many modern buildings, you'll find standard doorway widths that cater to everyday needs. These widths are typically measured from the finished wall surface to the opposite finished wall surface.

According to the International Residential Code (IRC), the minimum clear width for a doorway is 32 inches. This measurement ensures that a person using a wheelchair can pass through comfortably. However, for accessibility purposes, the Americans with Disabilities Act (ADA) recommends a minimum clear width of 36 inches for most doors.

Single Door Widths

Single doors are the most common type and typically have a width of 32 to 36 inches. This width allows for easy passage, even with objects like luggage or furniture.

For accessibility, consider using a 36-inch wide door. This width provides ample space for individuals using mobility devices, and it's also useful for moving large items through the doorway.

Double Door Widths

Double doors, also known as French doors or bi-fold doors, can significantly increase the doorway width. The width of a double door can vary, but it often ranges from 60 to 72 inches when both doors are open.

Double doors are common in large spaces like living rooms, dining rooms, or entryways. They allow for easier movement of large items and can create a more open feel between spaces.

While the standard doorway widths provide a good starting point, the ideal width can vary depending on the room and its intended use.

For instance, in commercial buildings, doorways may need to be wider to accommodate heavy equipment or high volumes of foot traffic. In contrast, doorways in older homes may be narrower due to the construction techniques and materials used at the time.

Bathroom Doorways

Bathroom doorways often have a narrower width than other doors in the home. This is because bathrooms are typically smaller spaces with less traffic. According to the IRC, the minimum clear width for a bathroom doorway is 24 inches.

However, for accessibility, the ADA recommends a minimum clear width of 32 inches for bathroom doors. This width allows for easier maneuvering of mobility devices and provides more space for users.

Closet Doorways

Closet doorways can be quite narrow, often ranging from 24 to 30 inches in width. This is because closets are typically small spaces with limited movement area.

However, if you're designing a walk-in closet or a large reach-in closet, you might want to consider a wider doorway. A wider doorway can make the closet feel more spacious and allow for easier access to the entire space.

Understanding doorway widths is crucial for creating functional, accessible, and comfortable spaces. Whether you're designing a new home, renovating an existing one, or simply looking to upgrade your doors, keep these measurements in mind. After all, the right doorway width can make all the difference in how you use and enjoy your space. So, measure twice, cut once, and you'll be well on your way to creating a home that truly fits your needs.
