From our friends at Home Depot:

Crafting your own DIY closet organizer is simple. You just need enough time and a little know-how. Start by measuring accurately. Accurate measurements are the secret to making any size closet more functional. 


You will install your finished DIY closet system on shelf supports. 


  • Measure the back wall and two side walls of your closet space. 
  • Use these measurements to determine the length of the shelf supports. 


Tip: Deduct 1 1/2 inches from the length of the back wall shelf support measurement to account for the 3/4-inch thickness of each side wall support.


You’ll use 3/4-inch plywood to make this closet organizer. Measure out:


  • Six 1-inch x 3-inch boards. The lengths will be based on the back and side wall measurements in Step 1.
  • Two 11 7/8-inch wide long closet shelves. Use the length that fits the width of your closet in Step 1.
  • Six 11 7 /8-inch square shelves for the central unit.
  • Two 11 7 /8-inch side pieces for the central shelf unit.

Use a circular saw to cut the following pieces you measured out in Step 2. 


  • Six 11 7/ 8-inch square shelves for the central unit. 
  • Six 1-inch x 3-inch boards with lengths based on the back and side wall measurements in Step 1.
  • Two 11 7 /8-inch wide closet shelves with lengths based on the closet width measurement in Step 1.


Your shelf support pieces will bear most of the weight of the central shelf unit. It’s important to attach them to the studs. Use a stud finder to find the studs in the back wall and the two side walls of your closet space.


  • Attach the supports for the top shelf to the walls with their top edges 84 inches above the floor using wood screws. 
  • Attach the supports for the bottom shelf to the wall with their top edges 76 inches above the floor using wood screws.


  • Use wood screws or finishing nails to put the center of the organizer together.
  • Space the shelves evenly. Or choose spacing based on the height of the items you plan to store.
  • Leave the top and bottom of the unit open.


  • Position the central shelf unit to be the middle of the DIY closet system.
  • Cut excess wood out with a hand saw so the unit fits into the support board. Take your time here and avoid removing too much wood.


  • Lay one of the long shelves on the lower shelf supports. It will be on top of the central shelf unit. 
  • Attach each long shelf with wood screws or 6d finishing nails.


Tip: Add metal shelving brackets in the corners of the long shelves for extra support.


Freestanding closet shelving comes in a wide range of designs and styles. Simply measure your available space and look for a unit that will fit. Choose from basic wire storage systems to high-end wood organizers perfect for upscale master bedrooms. Ready-made and ready-to-assemble closet organizers are also available. 


  • Freestanding wire organizers come with one or more shelves. 
  • Freestanding organizers in wood looks come with shelves. They can also have a combination of shelves and drawers. 
  • Freestanding plastic closet systems may have a hanging rod and shelves and storage baskets. 
  • Wire storage organizers can have drawers and baskets. Some are freestanding. Others hang over a door.


Tip: Large organizers may need to be assembled. Make sure they are anchored to a wall for safety and stability. Read the instructions that come with your unit for details.
