What is the minimum door height?

• A. 1980 mm (6'6")
• B. 1900 mm (6'3")
• C. 2000 mm (6'6")
• D. 2100 mm (6'11")

Answer: (A)

Head clearance and practical usability set the minimum door height. A height of 1980 mm (about 6 ft 6 in) is widely used as the minimum because it provides comfortable passage for most people and fits typical ceiling and framing dimensions without adding unnecessary cost. A door that’s lower, such as 1900 mm, could lead to headroom issues in everyday use and isn’t considered sufficient by standard practices. Taller options like 2000 mm or 2100 mm meet or exceed the minimum height but aren’t required for the minimum standard.
