How many hinges are typically on an exterior door?

1. 2

2. 3

3. 4

4. 5

The correct answer is: 3

The typical number of hinges on an exterior door is three. This configuration is widely used because it provides adequate support and stability for heavier doors, which are common in exterior applications. Three hinges help distribute the door's weight more evenly, reducing the likelihood of sagging over time, which can occur with fewer hinges. Additionally, having three hinges enhances security, making it more difficult for unauthorized individuals to force the door open. While it's possible for some doors to use two or even four hinges depending on specific design requirements, three hinges strike a good balance between functionality and stability for most standard exterior doors.
