Hinged exterior doors typically have three or four side-mounted hinges. The reason for using this number of hinges is to provide adequate support, stability, and security for the door, particularly for heavier doors made of solid materials like wood or steel.

Three hinges are commonly found on standard-sized doors, offering a balanced distribution of weight and helping to prevent sagging over time. For larger or heavier doors, four hinges can be used to distribute the weight more evenly, thereby enhancing durability and extending the door's lifespan.

Having too few hinges might result in alignment issues or hinder the door's operation, while an excessive number of hinges is generally unnecessary and can complicate installation and maintenance. Therefore, three or four hinges strike the right balance for most hinged exterior doors, ensuring both functionality and a secure fit.
