Sill height

In general residential buildings, the height of windowsill should not be less than 0.9m. When the height of windowsill is lower than 0.8m, protective measures should be taken. In public buildings, the height of windowsill varies from 1.0 to 1.8m, and the bottom height of the window sash opening to the public corridor should not be less than 2.0m.

Window height

In general residential buildings, the height of the window is 1.5m, plus the height of the windowsill is 0.9m, then the top of the window is 2.4m away from the floor. The height of the window should be determined according to the requirements of lighting, ventilation, space image, etc., but attention should be paid to the problem of high rigidity of the window. If necessary, beams or "splicing" should be added. In public buildings, the height of the whole glass has exceeded 7.2m, which is beyond the scope of ordinary windows.

Window width

Generally, the window width starts from 0.6m. According to the provisions of building standard opening specifications, the width modulus of general building opening is 300 mm, that is, the general width is 600mm, 900mm, 1200mm, 1500mm, and so on. It should be noted that when the window opening is too wide, the vertical keel or "joint" should be added. Otherwise, the stiffness problem of the window is easy to occur.

Height of door

The height of the door for people's passage is generally not less than 2m, and the height should not exceed 2.4m. Otherwise, there is a sense of cavity, and the door leaf production needs to be strengthened. If necessary for modeling, ventilation and lighting, waist windows can be added on the door, and the height should be 0.4m, but it should not be too high.

The door for vehicles or equipment to pass through shall be determined according to the specific situation, and its height shall be 0.3-0.5m higher than that of vehicles or equipment, so as to avoid collision with the door frame when the vehicle is bumpy or the equipment needs to be transported by cushion roller. As for the clearance requirements for various types of vehicles, the corresponding specifications should be consulted.

If it is a stadium, exhibition hall and other buildings with large volume and large space, if it is necessary to set super-scale doors, a conventional size auxiliary door can be added on the front door leaf, so that people can pass when the gate does not need to be opened.

Nowadays, there are many inspection doors for various equipment tube wells in the building, which are not often passed through. Therefore, the upper frame height is generally equal to or lower than the ordinary door, and there is a threshold with the same height as the skirting line at the bottom, so the net height does not have to be limited to 2m, about 1.5m. For hotel rooms, the net height of the door opening shall be no less than 2.1m.

Width of the door

In general, the household door is 0.9-1 m, the room door is 0.8-0.9 m, the kitchen door is about 0.8 m, and the toilet door is 0.7-0.8 M. due to the consideration of the moving in of modern furniture, the upper limit size is adopted now. The door width of public buildings is generally 1 m for single door and 1.2-1.8 m for double door. The production of door leaf should be considered when the width of double door or multi door is 0.6-1.0 M. Generally, the width of the door opening in the hotel room is greater than or equal to 0.9m, and the width of the door opening in the toilet is greater than or equal to 0.75m.

The width of the emergency exit for safe evacuation shall be set according to the calculation and specifications (relevant fire prevention regulations). The width of the door for maintenance in the pipeline well is generally 0.6m. In addition to its own width, only 0.3-0.5m gap is left on each side of the door for motor vehicles or equipment.
