A door is not only about aesthetics—it also affects comfort, safety, ventilation, and the overall spatial design. However, door dimensions vary across different regions, such as China, Europe, and America.
This article provides a comprehensive comparison of interior door sizes, standard bedroom door sizes, kitchen door size standards, and bathroom door sizes worldwide.
