What is the standard height of a residential interior door?

The standard height of a residential interior door is typically 80 inches. This measurement is widely accepted in building codes and industry standards for residential construction. Doors of this height offer a balance between aesthetics and functional use, providing ample entry space for most individuals while ensuring a good proportion with the surrounding walls. Standardizing the height helps maintain consistency in design and construction, which is an important consideration for builders and architects alike.

Other heights like 78 inches, 84 inches, and 86 inches may be used for specific applications or custom designs, but they do not represent the standard for typical residential doors. Such deviations may cater to architectural styles, specific building needs, or regional preferences but generally fall outside the commonly accepted norms.
