When it comes to choosing a new exterior door for your home, one of the most important factors to consider is the size. The size of the door not only affects the overall aesthetics of your home but also plays a crucial role in ensuring proper functionality and security. In this article, we will explore the standard exterior door sizes commonly used in homes today.

Standard Sizes

1. Single Doors

The most common type of exterior door is the single door. These doors typically come in three standard sizes: 30 inches, 32 inches, and 36 inches in width. The height is generally 80 inches, although some doors may be taller to accommodate taller individuals or custom specifications.

2. Double Doors

For larger entryways or a more grandiose appearance, double doors are often used. These doors consist of two panels that open from the center. The standard width for double doors is 60 inches, 64 inches, or 72 inches. The height remains the same as single doors, typically 80 inches.

Considerations for Choosing the Right Size

While the standard sizes mentioned above are widely used, it’s important to consider a few factors before finalizing your exterior door size:

1. Entryway Space

Measure the available space in your entryway to ensure that the door size you choose fits comfortably without obstructing any surrounding elements such as walls or furniture.

2. Accessibility

If you or someone in your household requires wheelchair accessibility, consider opting for a wider door size to accommodate easy access.

3. Aesthetics

The size of your exterior door should complement the overall design and style of your home. Consider the scale and proportions of your entryway to select a size that enhances the visual appeal of your home.

Custom Sizes

If the standard sizes do not meet your specific requirements, you can opt for custom-sized exterior doors. Custom doors can be designed to fit any dimensions, allowing you the flexibility to create a unique and personalized entryway.


Choosing the right size for your exterior door is an essential aspect of creating a functional and visually pleasing entryway for your home. By considering the standard sizes and taking into account your specific needs and preferences, you can make an informed decision that enhances both the aesthetics and functionality of your home.
