The number of floors of the shoe rack at the door should be determined according to the actual demand and space size. Generally speaking, it is more appropriate to choose a shoe rack with three or four floors. This can meet the daily needs of family members without taking up too much space. If there are many people in the family or many shoes are stored, you can consider choosing a shoe rack with five to six floors. However, it should be noted that too high a shoe rack may affect the appearance, and it is not convenient to take and put shoes.
