What is the standard interior door height for most residential interiors?

The standard interior door height for most residential interiors is 6 feet 8 inches. This measurement is commonly used in residential construction to ensure that most individuals can easily pass through the doorway without any issues. This height has been widely adopted in the industry due to its practicality and the overall aesthetic balance it offers in room proportions.

In many cases, using a door height of 6 feet 8 inches also allows for better utilization of space, especially in homes with standard ceiling heights. If doors were shorter, it could lead to a cramped feeling in the room and may hinder accessibility, especially for taller individuals. The 6 feet 8 inches height also provides room for the top of the door frame to accommodate standard architectural designs without disrupting the visual lines of the home’s interior.

The other measurements provided, while they may be used in specific situations, do not reflect the common practice for standard interior door installations in most residential settings. For example, 7 feet doors might be found in custom builds or in areas where higher ceilings are a design choice, but they are not standard. Similarly, the shorter heights do not meet the typical height for usability and aesthetics in most residential applications. Thus, 6 feet 8 inches is considered the norm for interior door heights
