In general, the house is divided into doors, room doors, kitchen doors, and bathroom doors, and the upper size is now taken in consideration of the entry of modern furniture. The door width of public buildings is generally 1m for a single door, and the width of the double door should be considered for the production of the door leaf, and the width of the door leaf of the double door or multiple doors is appropriate. The width of the gate for safe evacuation should be set according to the calculation and specification (relevant fire code).

The width of the pipe and the door for service is generally as follows: A door for motor vehicles or equipment to pass through a gap that is left on each side in addition to its own width. By the way, for overhaul"Manholes"Its size should not be less than that.
