Doors

Hinges on doors are not hung at equal spacings. In the UK hinges hang 6 inches down from the top of the door and 9 inches up from the bottom. This is because of the optical illusion created by the eyesight of 'foreshortening' when looking down at the bottom hinge. In the USA the space is 5" and 10" with the exception of some western states where 7" and 11" is the norm. The middle hinge is always placed equally between the two.

A French door was also known as a French window. Basically it was a window that served the purpose of a door at the end of the Renaissance period around the time of Louis XIV the Great, the Sun King. The original French doors were constructed of individual, single paned pieces of glass and wood. The window/doors led out on balconies and allowed for the maximum amount of light to enter the room.
