What is the standard height for a typical door?

  1. 6 foot 4 inches

  2. 6 foot 6 inches

  3. 6 foot 8 inches

  4. 7 foot 0 inches

The correct answer is: 6 foot 8 inches

The standard height for a typical interior and exterior door in residential construction is 6 feet 8 inches. This measurement has become the norm because it accommodates a wide range of building needs while ensuring sufficient headroom for most individuals. Doors at this height allow for easy access while avoiding the need for excessively tall or short frame constructions, which can lead to structural challenges. When designing or specifying building plans, it's crucial to adhere to this standard to maintain consistency in door heights across various areas of the structure, which assists with uniformity in aesthetics and functionality. Having a common height also allows for easier replacement and installation, as most pre-hung doors are manufactured to this specification. While other options exist, such as 6 feet 4 inches, 6 feet 6 inches, or 7 feet, they are less commonly used in typical residential applications. The choice of 6 feet 8 inches strikes a balance between accessibility and design efficiency, thus making it the preferred height for most doors.
