The area of ​​a standard walk-in dressing room is usually between 70 and 100 square feet (about 6.5 to 9.3 square meters), which is suitable for most families. It provides more storage space and layout freedom, and can accommodate more clothes, shoes, accessories, and even a small dressing table or seat.

An important reason for the popularity of walk-in closets is that they provide more storage space. In modern families, with the enrichment of material life, the number of clothes, accessories and shoes people own has increased dramatically, and traditional wardrobes often cannot meet these needs.
