What is a common standard interior doorway height?

• A. 6 feet 8 inches
• B. 8 feet
• C. 7 feet 2 inches
• D. 7 feet 6 inches

Answer: (A)

The common standard interior doorway height is six feet eight inches. This height provides comfortable headroom for most adults while fitting typical residential framing and ceiling heights. It’s a stock size widely used in construction, which keeps costs down and makes doors readily available. While taller doors like eight feet or even around seven feet two inches or seven feet six inches can be found in some homes or special designs, they’re not the standard due to added costs and framing considerations. Six feet eight inches strikes a practical balance between usability, building conventions, and economy.
