There is no one-size-fits-all formula when it comes to cupboard design. Think of where you want the cupboard situated, whether in your living room, kitchen or dining area, bedroom or elsewhere. Your thoughts must also consider the existing furniture and its dimensions, and the size of the other rooms including corridors and entrances. However, for a standard wardrobe size in a bedroom 7’x 10’ is commonly used as a minimum measurement. The depth usually is about two feet but if you are looking for a small one, it can be as narrow as 18 or even 12 inches only. But if space becomes limited then think collapsible wardrobes.
