The minimum door height equals which inches value?

• A. 6 ft 6 in
• B. 6 ft 4 in
• C. 6 ft 5 in
• D. 6 ft 7 in

Answer: (A)

Passing through a doorway requires enough headroom, and builders base this on practical, stock dimensions that fit typical framing and trim. The minimum height used in many residential guidelines is 78 inches, which is 6 feet 6 inches. This height provides comfortable clearance for most adults and aligns with commonly available interior door sizes, keeping framing, jambs, and hardware straightforward to install. A shorter height would reduce headroom for taller occupants, while taller options go beyond the practical minimum and add unnecessary cost.
