The size of the refrigerator you choose depends on the number of members who intend to use it. If you are a bachelor living by yourself, a single-door fridge should suffice. But if you are a family of more than two, you probably should opt for a double-door fridge. Also, a double-door fridge makes our home look more presentable. Despite being such an important part of our lives, we often take the refrigerator for granted.
