In Between Stud Storage: How to Use Your Garage Walls More Effectively

In-between stud storage means building shelves, inserting ready-made organizers, or adding hooks directly into the cavity between two wall studs in your garage. These cavities are typically 14.5 inches wide (with 16-inch stud spacing), 3.5 inches deep, and however tall your wall section is, giving you usable storage that sits flush with or recessed into the wall rather than sticking out into the garage floor space. If you're tight on floor and wall space, stud bay storage is a legitimate way to add organized capacity without losing a single inch of working depth.

Most people walk past these stud bays every day without thinking about them as storage. A garage with eight exposed stud bays on the back wall and 8-foot ceilings has roughly 80 linear feet of potential shelving in spaces that are currently doing nothing. This guide covers the methods for using stud bays, what to store there, how to add shelves or organizers, and when this approach makes sense versus mounting standard wall storage on top of drywall.

Why Stud Bay Storage Works in Garages

The garage is one of the few places in most homes where in-wall storage makes practical sense. In finished living spaces, you typically have drywall on both sides and insulation between, making stud bay access complicated and visually out of place. Garages, especially unfinished ones with exposed studs, let you access these bays directly.

The depth of a stud bay, 3.5 inches for a 2x4 wall, is surprisingly useful for certain items. Spray cans and aerosols fit perfectly in a 3.5-inch deep shelf. Power tool batteries, charging equipment, electrical tape and similar supplies, first aid kits, small parts bins, and canned goods all sit flush in a stud bay shelf. The result is storage that essentially disappears into the wall, keeping your floor and main wall surfaces clear.

For a finished garage with drywall, some homeowners cut out sections of drywall between studs to create recessed storage niches. This requires more work but creates a polished, built-in look.

Types of In-Between Stud Storage Solutions

DIY Plywood Shelves

The most common approach is cutting small shelves from 1/2-inch or 3/4-inch plywood and nailing or screwing them directly to the sides of the studs. A shelf cut to 14 inches wide and 12 inches deep sits in the bay with a small front reveal and holds a surprising amount of organized supplies.

You can add 3 to 5 shelves per stud bay depending on what you're storing, creating a narrow but tall cubby for spray cans, hand tools, batteries, or garage supplies. Paint the shelves to match the wall for a cleaner look.

Cost for this approach: $5 to $15 per bay in materials if you're using scrap plywood, up to $30 to $50 per bay for clean lumber and finish.

Premade Stud Bay Organizers

Several companies make ready-made organizers specifically designed for stud bay installation. These are typically plastic or metal units that slide into a standard 16-inch-on-center stud bay and screw to the flanking studs.

Common examples include: - Rubbermaid ActionPacker stud bay kits - Akro-Mils wall-mount storage bins that fit stud bay dimensions - Custom plastic bin organizers designed for spray paint can storage

The advantage of premade organizers is that you get finished edges, consistent dimensions, and often a purpose-specific design (like a rack specifically for holding 12-ounce spray cans in tidy rows).

Magnetic Strips and Tool Rails

A thin magnetic tool strip or tool rail screwed directly to a stud face inside the bay uses the bay space without adding any shelf depth. Magnetic strips for holding screwdrivers, chisels, and other metal tools cost $15 to $40 and install with two screws. This works well in a dedicated small-tools bay where you want your commonly used implements visible and accessible.

Recessed Charging Stations

A stud bay can be converted into a recessed charging station for cordless tool batteries. Run an electrical outlet into the bay (requires a permit and should be done by an electrician unless you're experienced with electrical work), add a few shelf dividers, and you have a recessed charging station that keeps battery chargers and batteries organized and out of the way.

This requires careful planning: you need access to the wall cavity from behind, or the outlet needs to be a surface-mount unit on a new circuit.

What to Store in Stud Bay Shelves

The 3.5-inch depth of a standard 2x4 stud bay is the determining factor for what stores well here.

Items that fit perfectly: - Standard spray cans (aerosol paint, WD-40, contact cleaner) are about 2.5 to 3 inches in diameter - Power tool battery packs (most 20V/18V packs are 3 to 4 inches thick) - Small parts organizers with shallow compartments - Electrical tape, zip ties, and similar small hardware supplies - First aid kit contents or a small first aid kit box - Garage door remote controls and spare batteries - Mechanic's stethoscope, timing light, and similar long, thin tools

Items that don't fit: - Standard paint quarts (3.5 inches is just barely too narrow for a round can without the handle) - Most cordless drills and power tools (too bulky) - Anything that extends more than 3 inches from the stud face

For a 2x6 wall (common in newer construction or exterior-facing walls), the bay is 5.5 inches deep, which opens up significantly more options including regular round paint cans.

How to Add Shelves to Exposed Stud Bays

For an unfinished garage with exposed studs, adding shelves is straightforward.

Cut shelf boards from 1/2-inch plywood to 14 inches wide (the clear span between studs on 16-inch centers with standard stud width) and whatever depth you want, typically 10 to 12 inches. A 10-inch depth uses most of the stud depth while leaving a bit of the stud face proud for visual reference.

Mark level lines on the stud faces at your desired shelf heights. Pre-drill through the shelf ends to avoid splitting. Drive two screws through each shelf end into the flanking stud. Use 2-inch or 2.5-inch construction screws with a washer if the plywood is 1/2-inch (washers prevent the screw from pulling through).

Add a front lip of 1x2 or 1x3 lumber along the front edge of each shelf to prevent items from falling out. This is especially important for spray cans and small parts containers that could roll off during a door slam or vibration.

Planning a Full Wall of Stud Bay Storage

If your garage has a full exposed-stud back wall, planning the storage intentionally before adding any shelves pays off.

First, identify which bays have electrical wiring or plumbing in them and leave those clear or plan shallower shelves that won't interfere with the infrastructure. Outlet boxes are already set back 1/4 inch from the stud face in most cases, but wiring that runs up through a bay needs to stay accessible.

Then categorize your storage by zone. In my experience, a logical arrangement puts: - Automotive supplies (oils, filters, cleaners) in the bays closest to the car parking position - Garden chemicals and fertilizers away from flammable materials and elevated above floor splash level - Small hardware bins near the workbench - Safety and emergency supplies near the main entry

Stud Bay Storage in Finished Garages

For a finished garage with drywall, cutting access to stud bays is more work but completely achievable as a weekend project.

Mark the stud locations carefully, then cut the drywall between studs using an oscillating tool or drywall saw. Cut the drywall flush with the inside faces of the flanking studs, giving you a clean recessed opening.

Frame the opening with thin lumber or finish trim to create a clean edge, add shelves as described above, and paint to match. The finished result looks intentional and far better than a patched drywall repair.

For particularly heavy storage needs in a finished garage, adding a recessed cabinet that fills the full bay depth and installs flush with the wall surface creates a built-in cabinet look that's visually polished and maximally space-efficient.

FAQ

Do I need a permit to add stud bay shelves in my garage? Adding simple shelves between wall studs is not structural work and doesn't require a permit in most jurisdictions. If you're adding electrical outlets or running new wiring, that work typically does require a permit and inspection. Check local requirements before doing any electrical work.

Can I use stud bay storage in an exterior garage wall? You can, but exterior walls typically have insulation in the stud bays. Removing insulation to create storage in an exterior bay will reduce the thermal performance of that wall section. For a conditioned or heated garage where energy efficiency matters, the tradeoff isn't worth it. For an unheated garage, it's less of an issue.

What's the maximum weight I can put on a stud bay shelf? A shelf screwed into two flanking studs with appropriate screws can hold 50 to 100 lbs before the screw joints become the limiting factor. For most stud bay storage (spray cans, batteries, small tools), this is far more than needed. Don't exceed 30 to 40 lbs per shelf as a practical guideline.

Can I add stud bay storage if the bays have OSB sheathing on the exterior? Yes. The sheathing is on the outside of the studs, and your shelving goes on the inside. As long as you're not penetrating the sheathing (which you wouldn't be for interior shelves), the presence of exterior sheathing doesn't affect interior stud bay storage.

The Bottom Line

In-between stud storage is one of those solutions that makes you wonder why you didn't do it sooner. It's inexpensive, the installation is simple, and it adds usable organized storage without taking any floor or wall face space. Start with one section of wall, pick the supplies that fit perfectly in the 3.5-inch bay depth, and add a few simple plywood shelves. If it works well (and it will), extend the system down the wall.
