A wardrobe and an armoire are very similar in nature. They are both pieces of furniture traditionally used primarily for storing clothing. The main differences between a wardrobe and an armoire relates to the size and style of these pieces of furniture. Wardrobes usually are smaller and less detailed. An armoire typically features intricate designs and stylish hardware, and some types of an armoire are used to house an item such as a television set or computer.

The term "wardrobe" typically refers to a tall wooden cabinet with two doors. It typically is used for storing clothing and accessories, although in medieval times, it more often was used for storing machinery. A wardrobe usually incorporates a long rod for hanging clothing. It might also include a mirror as well as drawers or shelves for storing accessories or smaller items.

The term “armoire” means “cupboard” in French. Like a wardrobe, an armoire typically is built as a tall cabinet with two doors and a long rod for hanging clothing. It might contain shelving, and it usually features ornate designs. Centuries ago, armoires were primarily used to store weapons and armor.

One difference between a wardrobe and an armoire is that some varieties of an armoire incorporate a very large shelf that makes it useful as a storage area for a television or computer. This is referred to as an entertainment armoire or a computer armoire. The doors of this type of armoire can remain open when the television or computer is in use, then can be closed afterward to conceal the equipment. This can give a room a more formal look than a typical entertainment center or computer desk.

There are numerous styles of wardrobes and armoires available. Both an wardrobe and an armoire traditionally have been built from wood, such as oak or mahogany. Some modern versions made from plastic or wood veneer cost less but might not provide the same look or sturdiness. Antique armoires can be quite expensive and usually are quite large. Wardrobes generally are cheaper than armoiress because of the simplistic nature of their design and their smaller size.
