If you’re on a tight budget, the least expensive material you can buy for DIY closet shelves is chipboard, a.k.a. particle board. This inexpensive material is made from a pulp of sawdust, resin, and glue that’s pressed together under high temperature and pressure. As you can imagine, it’s not very sturdy and might buckle under your blue jean collection, so you should only use it if you’re storing very light items. 

On average, building a custom or built-in closet costs around $2,100. However, the total price can range from as little as $500 for a simple DIY project to $6,000 or more for a large, high-end custom closet. Most projects typically fall between $1,500 and $5,000.

The final cost depends on several factors, including the closet's size, type, materials, and features. Here is a general cost breakdown by closet type:

• Reach-in closet: $500 to $1,500

• Walk-in closet: $750 to $5,000

• Wardrobe: $2,000 to $6,000 or more

Choosing a prefabricated closet system is generally less expensive than a fully custom build. The scope of design and construction services will also significantly impact the price.

Walk-in closets are always the biggest and can easily be more than 100 square feet. Primary bedroom closets, even if not walk-ins, are the second largest category in most homes and sit between 30 and 80 square feet. Linen closets, utility closets, and built-in closets are smaller and, depending on their usage, tend to be between 10 and 50 square feet.

Yes, books are typically heavier than clothes, unless you have a collection exclusively of paperbacks or comic books. That’s why packing lots of books warrants careful planning and consideration. Consider packing up your reading collection first to determine whether you need to downsize it before loading it into your moving truck.
