How to build simple DIY garage storage shelves using 2x4s and plywood. This project takes about 4 hours and is an affordable project.
Keeping our garage organized is a never-ending battle. Every time either one of us works on a project we just clear an area to work in. Everything else gets pushed to the side. It’s a terrible system.
To solve our issue, we built DIY garage storage shelves. The shelves utilize our vertical space. This leaves more floor space for projects.
Storage boxes, filled with holiday decorations and childhood treasures, were the biggest culprit of chaos. We decided to build the garage shelves to fit all of these storage bins.
The corner next to the garage door was the perfect size for shelves to hold those boxes. Our design included 3 shelves, plus space underneath for gas and weed killer. Never keep hazardous materials on shelves where they could fall on you!
We measured our space and decided the best dimensions would be 34″ wide and 5′ long. This size allows the garage door to open and close without issue.
Then, we measured the height of the storage boxes. These measurements determined the required height of each shelf.
We decided around 20″ was best. This meant the shelves were about 6 ft tall in total.
I need a step stool to reach, but my husband reaches the top easily.
DIY Garage Storage Shelves
- 2 4×8 plywood sheets
- 10 8 ft. 2x4s
- 1 box 3″ deck screws
- 1 box 1 1/4 screws (for attaching the plywood)
- 4 2×4’s @ 6 ft. (shelf legs)
- 6 2×4’s @ 57″ (shelf supports)
- 6 2×4’s @ 31″ (shelf supports) Use leftover 2×4’s
- 2 4×8 plywood sheets @ 57″ by 34″ (bottom 2 shelves)
- 2 plywood sheets @ 30″ by 34″ (top shelf)
How to Build DIY Garage Storage Shelves
Assembling the Shelf Frame
First, cut the 2×4’s down to create the shelf legs and supports. Then attach a 57″ shelf support 20 inches from the bottom of the legs. This is the front of the shelves.
Attach the remaining shelf supports, with a 20-inch gap between the supports.
Next, flip this side of the shelf onto the side. One 2×4 for the leg should lay flat on the ground, with the supports and the other leg in the air. Attach the side supports to both the leg and the front support.
Then, assemble the back of the shelf. Attach the 57″ supports every 20″ along two shelf legs.
Lay the back of the shelf on top of the side supports and attach. Then flip the frame up so it stands on the legs.
Attaching the Storage Shelves
After the frame is assembled it’s time to start attaching your shelves!
Cut the plywood into 2 57″ by 34″ for the bottom shelves. Use the leftover plywood to make 2 30″ by 34″ pieces. These make the top shelf. Using leftover plywood keeps you from purchasing a third sheet!
Use the 1 1/4″ screws to attach the plywood to the tops of the supports. Attach them every 6 inches for sturdy shelves!
At this point, we could have painted the shelves or stained them. But they are just going in the garage. No need to be fancy!
I immediately loaded the shelves after we finished building. Finally, it felt so good to get all that crap off the floor! We brought some order to the garage chaos.
Along with the storage boxes, I loaded the shelves with bags of potting soil, a bin of scrap wood, and a bin of cardboard.
