What is the standard height of an interior door?

The standard height of an interior door is typically 6 feet 8 inches. This measurement has been widely adopted in residential construction as it provides adequate clearance for most individuals while also allowing for ceiling heights that accommodate various architectural designs.

When constructing or remodeling interiors, using a standardized door height simplifies procurement and installation, as manufacturers produce doors primarily in this dimension, making them readily available. This ensures not only aesthetic congruency but also functional utility in standard rooms, where this height suffices for general movement and accessibility.

Other measurements, while used in certain circumstances or specific styles, do not match the common standard and might limit options for door selection and compatibility with existing frames in many building scenarios.
