What is the size range for the widths of exterior doors?

The size range for the widths of exterior doors typically falls between 24 to 36 inches. This standard sizing reflects common building practices and ensures compatibility with most residential and commercial door frames. A width of 32 inches is often considered the minimum for wheelchair accessibility under guidelines set by the Americans with Disabilities Act (ADA), which promotes accessibility for individuals with disabilities.

Exterior doors can also come in wider sizes, usually extending up to 36 inches, to accommodate various design preferences and practical uses, such as moving large items in and out of a home. Sizes beyond this range are less common for standard doors and are usually reserved for high-traffic areas or specialized applications.

As a result, the option of 24 to 36 inches accurately aligns with the established standards for exterior door widths and practicing builders and contractors.
