Types, Widths and Positions of Doors

Internal doors must be positioned in order to maximise the usable room space ⟶① – ⑧. It is necessary to decide whether a door should open inwards or outwards. Normally doors open into the room ⟶③ – ⑤. Door types are named according to their construction, position and purpose.

The width of a door is determined by its use and the room into which it leads. The minimum inside width of a door opening is 55 cm. In residential buildings the standard door opening widths are as follows:

  1. Single-panel doors: main rooms approx. 80 cm, auxiliary rooms approx. 70 cm, front doors to flats approx. 90 cm, front doors to houses up to 115 cm.
  2. Double doors: main rooms approx. 170 cm, front doors 140 – 225 cm.
  3. Door opening height at least 185 cm, but normally 195 – 200 cm.
  4. Sliding and revolving doors are not permitted for escape or exit doors, as they could block the route in an emergency.

Disabled persons have special requirements. The minimum convenient door width for the ambulant disabled is 80 cm. This is to narrow for wheelchair users, but 90 cm is usually adequate. There should be adequate space be not less than 120 cm wide so that wheelchair users can position themselves to open a door in the end of a corridor or at the side. And end door should be offset to give maximum space beside the handle. Similarly, when a door is located in the corner of a room, it should be hinged at the side nearer the corner.

This types and the widths of doors is taken from the book Architects’ Data written by Ernst and Peter Neufert, whereas this book has become the guideline for architecture college students in the world.
