Different types of closets are defined mostly by size. A few different types of closets include:

• A reach-in closet is a smaller closet that you can stand in front of and reach everything inside it. Aside from the size, the doors and the level of drywall finish are typically the largest price factors.  

• A walk-in closet can be anything from a small 5-by-5 feet closet that has a narrow walkway with shelves on both sides to a 100 square foot bedroom-sized closet with shelving along the walls and plenty of room to move around in.

• A built-in wardrobe often does not have a door and leaves the clothes and other contents open to the room, whereas a closet usually has a door to separate it from the rest of the room.

You can budget a little less money for how to build a closet with wire shelves than with wood shelves. Some people don’t like the aesthetics that wire shelves provide, though, meaning they’ll gladly spend a little more to add wood shelves to the build. If you decide to buy pre-made wire shelves instead of building custom-sized wood shelves, you’ll be restricted in the closet shelving dimensions you can use.

Plywood offers excellent stability and strength for drawer construction. Baltic birch plywood provides a premium appearance, while standard hardwood plywood offers good value. Solid wood works well but requires more attention to grain direction and seasonal movement.

Yes, 12-inch shelves are often considered the standard closet shelf depth for storing folded clothing, shoes, and small containers. However, if you plan to store bulky items such as blankets, baskets, or cleaning supplies, you may want to go deeper. For specialized layouts, an adjustable system can give you more flexibility.
