What is the recommended gap between a door and its frame?

The recommended gap between a door and its frame is 1/8 inch. This specification ensures that the door can open and close smoothly without binding against the frame. A gap of this size allows for proper air circulation, accommodates expansion and contraction of the door materials due to temperature and humidity changes, and helps prevent wear on the door and frame.

By adhering to the 1/8 inch gap guideline, homeowners and builders minimize the risk of issues such as warping, sticking, or uneven wear of the door over time. This standard spacing is particularly crucial for interior doors where functionality and aesthetics are important, ensuring that the door sits neatly within the frame while still allowing for necessary movement.
