Closet design services include help designing and laying out your closet for maximum utility, visual appeal, and return on investment. Many closet designers can also include the carpentry required to construct your custom closet. You should speak with your designer beforehand to determine what services are included in the estimate, and prepare to lay out additional funds for materials or labor as needed.

Plywood, MDF (medium-density fiberboard), and solid wood are all popular options for closet shelving. Plywood and solid wood are sturdy and ideal for extended shelves or heavy items. MDF is a budget-friendly choice for light to moderate storage, but it can sag under heavy weight if not adequately supported. Wire shelving is another alternative that allows airflow, making it especially useful in humid spaces such as laundry rooms or basements.

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.

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.
