What is the typical width of an exterior door?

The typical width of an exterior door is 32 inches. This dimension is commonly used in residential construction because it provides a balance between accessibility and structural integrity. A 32-inch door allows for easy passage of people and furniture, ensuring that movement in and out of the home is practical and convenient. It also meets most building code requirements for residential accessibility, making it compliant for individuals with mobility challenges.

In addition, a 32-inch door can accommodate standard door frames, which helps reduce installation complications and ensures a good fit for various styles of exterior doors, including single doors or those that may pair with sidelights or transoms.

While options like 28 inches, 30 inches, and 36 inches can be found, they are either less common or used in specific applications. A 28-inch door may be too narrow for some uses, and a 30-inch door, while somewhat standard, is still less typical than 32 inches. Conversely, a 36-inch door is often seen in commercial applications or as a wide access entry but may not be as suitable for standard residential settings where space is at a premium. Thus, 32 inches stands out as the most typical choice for exterior doors in a residential context.
