Interior door heights are typically standardized to what measurement?

The standard height for interior doors is typically 6 feet 8 inches. This measurement has become widely accepted in residential construction and is used by most manufacturers, ensuring consistency across the industry. The reasoning behind this standard is that it provides enough clearance for most individuals, accommodating average height needs without being excessively tall, which could complicate installation and design. Furthermore, this measurement aligns with the dimensions used in many building codes and architectural plans, making it a practical choice for builders and contractors.

While other door heights, such as 6 feet 6 inches, 7 feet, or 7 feet 6 inches, do exist, they are less common and often used for specific situations or custom designs. The use of the standardized height of 6 feet 8 inches allows for efficiency in production and installation, contributing to overall project timelines and costs.
