A door may be defined as a framework generally, consisting of wood, steel, aluminium, glass or a combination of these materials, secured in an opening left in a wall for the purpose of providing access to the users of the structure. It basically consists of two parts,

• a frame and
• shutter (leaf).

Timber, plywood, glass, block etc are used for shutter.

Aluminium doors are considered to be the best as they are rust proof and present an elegant appearance. However since aluminium is costly as compared with timber or steel, use of aluminium doors is normally restricted to public buildings.

The designer or planner of a building should observe the following rules while deciding the
location of doors :

• The number of doors should be kept minimum for each room, because larger
  number causes obstruction and thus, decreases utility of the accommodation.
  The location and size of a door should be based on its functional requirements.
  
• From point of view of utility of the accommodation and the primary need of the
  occupants, doors should preferably be located near the comer of a room (nearly
  20 cm from the comer).
• From point of view good ventilation and free air circulation inside the room, the
  doors should be located in opposite walls facing each other.
• The location, number and size of doors are also decided considering the various
  factors, namely, desired day light, desired vision of outside, privacy, natural
  ventilation, heat loss, etc.
• In addition to above listed factors, doors should preferably be located with a
  view to improving the interior decoration of a room.

In the context of doors, size means its width x height. In general, a door should he of such
dimensions that it allows the movement of the largest object likely to be passed through the
door. While in case of residential buildings it should be aimed that two persons walking
shoulder to shoulder can freely move through the door; while in public buildings, bigger
sizes are used. Normally, the sizes of doors provided in different locations in the buildings
are as follows :

1. Internal doors for residential buildings : 0.9 m x 2 m
2. External doors for residential buildings : 1.0 m x 2.0 m
3. Doors for bath rooms and water closets in residential buildings : 0.7 m x 2.0 m
4. Doors in public buildings, viz. hospitals, libraries, cinemas, etc. : 1.2 m x 2.25 m
5. Doors in garages : 2.5 m x 2.25 m

Note : Minimum height of a door should not be less than 1.80 m.
Common criterion for sizes of doors used is as follows :

1. Width = 0.4 to 0.6 x Height, or
2. Height = Width + 1.2 m.
