Space and Functionality
The size of a door should align with the space it serves. Consider the room's purpose and the amount of traffic it will handle when selecting a door size. For instance, a bathroom door may be smaller than a bedroom door due to space constraints.
Material and Design
Door materials and designs can also influence size choices. Heavier materials like solid wood may require larger frames for stability, while lightweight materials like aluminum can accommodate smaller dimensions.

Proper maintenance ensures that your doors function well and last longer. Regularly check hinges, locks, and weatherstripping for wear and tear. Lubricate moving parts and clean the door surfaces to prevent damage from moisture and dirt.
