However, some interior doors may be wider, such as those leading to master bedrooms, closets, or other large spaces. These can range from 34 to 36 inches wide, depending on the specific needs and design of the home.

Exterior Door Widths

Exterior doors in homes typically measure 36 inches wide to accommodate larger items, such as furniture or appliances, that may need to pass through them. This width also provides better insulation and can help improve energy efficiency.

Additionally, some exterior doors may be even wider, such as those leading to garages or patios, which can range from 36 to 48 inches wide or more, depending on the specific needs and design of the home.

Public Building Door Widths

In public buildings, such as hospitals, schools, or government facilities, door widths can vary greatly depending on the specific needs and design of the building. However, many public buildings strive to meet accessibility standards, which often require door widths of at least 32 inches.
