Optimum visible light size of kitchen door

Door leaf width = doorway width-60mm, door leaf height = doorway height-40mm. Opposite door: single door leaf width = (door width -50mm)/2.

It is the size of the door opening, that is, the minimum size of the door frame, and the auspicious size is selected according to the actual situation of Lubanchi. Downshift: it is the threshold, which is generally high before and low after, 45mm before and 55mm after. Therefore, the reserved size of houses without floor tiles also needs to be included in the downshift. Usually the floor tile is 50mm, and the clearance height is deducted by 3-4 cm. Doors, doorposts and gates all like to match doorposts. The effect is luxurious and atmospheric. It is worth noting that the doorposts are installed above and on the left and right sides of the doorway, not inside the doorway. Therefore, it is necessary to consider whether the actual situation of the facade will limit the doorposts.
