Interior Doors Standard Widths
Interior doors play a critical role in transforming a home, and yet are often seen as a necessary component of a home’s design and not a major element. But many homeowners might be surprised to learn that interior door sizes vary greatly. The standard interior door width is typically 24 and 28 inches for residential homes. However, it is important to note that these measurements can vary based on the door style, manufacturer, and application.
Interior Door vs. Exterior Door Standard Widths
It’s important to differentiate between interior and exterior door widths. Many exterior doors come in standard widths of 36, 32, and 48 inches wide depending on the size of the opening. In contrast, interior doors have an array of standard widths, although the most generally accepted standard size is 32 inches wide. It’s also important to note that standard interior door dimensions typically range from 30 to 36 inches wide and 80 to 96 inches high.
Interior Door Standards by Prefabricated Doors
If you are replacing or installing prefabricated doors, you will want to check the manufacturer’s measurements before purchasing any items. Most prefabricated doors come in three standard sizes. The most popular size is 32-inches wide with a height of 80 inches. The next two sizes are 36-by-80- inches and 28-by-80- inches. Both of these widths come in both single and double variants.
Interior Door Standards by Custom Doors
The standard interior door width by custom doors can be any width that an individual wants. With custom doors, individuals can customize the size and design of the door to fit the opening to the exact dimensions provided. If you are looking to customize interior doors, you will likely have to purchase custom-made doors to meet the specific height and width requirements. Custom door selection and installation require more attention to detail but can produce more beautiful and unique results than with prefabricated doors.
Structural Limitations on Door Dimensions
When considering door dimensions, it is important to consider the limitations in the home’s structural composition. Prefabricated doors come in specific sizes that must be accounted for. But with custom-made interior doors, consider the structural dimensions of the doorway carefully before purchasing custom-made doors. Factors such as ceiling height, structural width, flooring and trim, baseboards, and any doors that may be adjacent to the opening should all be considered.
Summary
The standard width of interior doors for residential homes is 24 and 28 inches, though this can vary based on style, manufacturer, and application. Exterior doors usually come in standard widths of 36, 32, and 48 inches. When it comes to pre-fabricated doors, the most popular size is 32-inches wide by 80-inches high. Meanwhile, custom interior door widths vary depending on the size of the doorway. It is important to consider structural limitations when replacing or installing interior doors, such as ceiling height, structural width, flooring, and trim.
