Door clearance varies depending on the type of door and flooring. Generally, you need about 1/8 inch (3.2 mm) at the top and sides and approximately 1/2 inch (12.7 mm) at the bottom for interior doors. This ensures smooth operation and air circulation. For exterior doors, ensure sufficient space for weatherstripping and insulation. Always double-check clearance allowances specified by the door manufacturer to avoid installation issues.
