Spaces in homes should not be inaccessible to anyone because of an inability to get through a doorway. Wide doorways are useful for all sorts of individuals, including (but not limited to) those who use wheelchairs, those with larger body types, and/or with several kids in tow. Just about anyone with arms loaded with items will appreciate plenty of clearance. 36″ doorways are ideal, though 32″ doorways (interior only) are functional for most people if space is limited.
