Garage Shelving 600mm Deep: What This Size Does Well and When to Use It
Garage shelving at 600mm deep (about 23.6 inches) sits right at the sweet spot between light-duty residential shelving and full industrial depth. It's wide enough to store large bins, automotive equipment, and tool cases side by side without hanging over the edge, but not so deep that you lose items in the back or can't reach the rear of the shelf comfortably.
If you're searching specifically for 600mm deep shelving, you're probably based in the UK or Australia where metric sizing is standard, or you've found that shallower shelves aren't cutting it for what you need to store. This guide covers what 600mm depth gives you, the common formats this size comes in, and how to choose the right system for your garage.
Why Shelf Depth Matters More Than People Expect
Most people think about shelf width and height when buying storage. Depth is the dimension that determines whether things actually fit and whether you can keep the shelf organized long-term.
Common storage items and what depth they need:
- Standard Sterilite or Hefty 30-gallon tote: about 18 inches (457mm) deep
- Large 66-gallon tote: about 23 to 24 inches (585 to 610mm) deep
- Automotive fluid jugs (2-gallon): 6 to 8 inches deep
- Cordless tool cases: 10 to 16 inches deep depending on brand
- Portable air compressors (small pancake): 18 to 20 inches deep
- Shop-vac: 18 to 20 inches deep
A 600mm shelf handles all of these comfortably. Shallower shelves at 450mm (18 inches) handle the smaller items but require large totes to either overhang the front or be stored diagonally, which wastes space and looks messy.
Common Formats for 600mm Deep Garage Shelving
Freestanding Boltless Units
The most common format is a freestanding boltless shelving unit where you can choose the depth. Many manufacturers offer the same frame in 450mm and 600mm depth variants. The 600mm version costs slightly more and takes up more floor space, but holds dramatically more usable volume per shelf.
A 1200mm wide x 600mm deep x 1800mm tall 5-shelf unit gives you about 3.6 square meters of shelf area. At 250 kg per shelf capacity (a typical rating for this size), you have 1,250 kg of total storage capacity. That's a serious amount of gear.
In inch terms: a 48-inch wide x 24-inch deep x 72-inch tall unit with five shelves at 250 lbs per shelf.
Wall-Mounted Bracket Systems
Wall-mounted shelves at 600mm depth are available but less common than freestanding units because the depth requires heavier-duty brackets. A 600mm shelf extends 24 inches from the wall, which creates significant leverage on the bracket mounting points.
For wall-mounted 600mm shelving, you need: - Brackets rated for the extended depth load (not just weight rating) - Lag screws into studs, not drywall anchors - Thick brackets, typically 6mm or thicker steel
The advantage of wall-mounted at this depth is floor space savings. A wall-mounted 600mm shelf over a workbench or along a full wall keeps that area clear underneath for equipment, vehicles, or workflow space.
Pallet Racking Style Systems
Some garages use lightweight pallet racking. These are the orange or blue uprights-and-beam systems you see in warehouses, scaled down for residential use. They're available in 600mm depth and offer much higher weight capacity than residential boltless shelving.
Residential pallet racking (brands like Edsal or similar) handles 500 to 1,000 kg per shelf level and is adjustable in height at 75mm increments. The trade-off is installation complexity and the fact that these systems look very industrial.
For garage use where you're storing heavy automotive equipment, motorcycles, or workshop materials, the capacity justifies the look.
Comparing 600mm to Other Common Depths
| Depth | Best For | Trade-offs |
|---|---|---|
| 300mm (12 in) | Wall cabinets, small parts | Too shallow for large bins |
| 450mm (18 in) | Light garage storage, most bins | Large totes overhang |
| 600mm (24 in) | All-purpose garage storage | Takes more floor space |
| 750mm (30 in) | Heavy workshop/warehouse | Deep enough to lose items in back |
For most garages with mixed storage needs, 600mm hits the right balance. You can store your largest totes flat, double-stack smaller bins, and still reach the back of the shelf without a step stool.
Floor Space Math for 600mm Shelving
Before buying, check your floor space. A 1200mm wide x 600mm deep unit needs: - 1200mm of wall space (about 4 feet) - 600mm of floor depth from the wall (about 24 inches) - Clear access space in front (typically 600 to 900mm minimum for pulling totes)
Total footprint from wall to clear aisle: about 1,200 to 1,500mm (4 to 5 feet).
In a standard two-car garage 5.5 meters wide (about 18 feet), two 1200mm shelving units side by side along one wall occupy 2,400mm of the wall and about 600mm of depth. That leaves over 3 meters of width available for vehicles, which is enough for two average-sized cars if the rest of the wall is kept clear.

Best Brands for 600mm Deep Garage Shelving
In the UK and Australia, where 600mm metric sizing is standard:
BiGDUG: UK-based shelving manufacturer offering heavy duty racking in 600mm depth. Popular with UK garage owners who need high capacity at reasonable prices. Their zinc-coated steel holds up well in damp garage environments.
Metaltech (Australia): Common in Bunnings stores, offers 600mm deep steel shelving in powder-coated finishes at mid-range prices.
Edsal: US brand available online with 24-inch (approximately 600mm) depth options. Good value, available in black and gray finishes.
Gorilla Rack: US brand commonly available at Costco and Sam's Club. Their 24-inch deep units are a popular choice for garage use.
In the US, 24-inch depth shelving from any of the major brands (Gorilla Rack, Edsal, Muscle Rack, Seville Classics) is equivalent to 600mm.

Installation Tips for 600mm Freestanding Units
600mm units are heavier to move once loaded. Position the unit before filling it. A 1200mm wide unit fully loaded with totes can weigh 400 to 600 kg, which is not something you want to slide across concrete.
Place a rubber mat under the leveling feet if the floor is sloped toward a drain. This gives the feet grip and reduces scratching if you ever do need to shift the unit.
On very uneven concrete, shim under the feet with steel shims rather than plastic. Steel shims compress less under load and stay in position better.
If the unit is near a wall, attach it with an anti-tip strap even if not required. 600mm deep units loaded top-heavy can tip forward when the top shelf is heavily loaded and the bottom is light.
FAQ
Is 600mm deep shelving too deep to reach the back? For most people, reaching 600mm (24 inches) to the back of a shelf at mid-height (around waist to chest level) is comfortable without stretching. For top shelves above shoulder height, you'll want a step stool to see and reach the back. This is normal for any shelving over about 1.5 meters tall.
Does 600mm shelving work in a garage with limited floor space? If floor space is at a premium, consider wall-mounted 600mm shelving above the workbench height. You get the depth benefits without losing floor access below. Alternatively, use 450mm depth for wall-mounted shelves and reserve 600mm depth only for freestanding corner units where depth is less disruptive.
Can I use 600mm shelving as a room divider in my garage? Yes. Double-sided shelving units (accessible from both sides) at 600mm depth work well as garage room dividers, creating a workshop zone on one side and a storage zone on the other. Load them from both sides for maximum efficiency.
How does 600mm shelving compare to garage cabinets at the same depth? Cabinets at 600mm depth give you the same storage volume but with doors that hide the clutter and protect items from dust and garage contaminants. Open shelving is easier to load and access quickly. The choice depends on how much visual organization matters versus access convenience.
When 600mm Is the Right Choice
If you're storing large bins, automotive equipment, workshop supplies, or anything that consistently hangs over the front of an 18-inch shelf, 600mm is worth the extra floor depth it requires. The extra 6 inches of depth per shelf adds about 33% more storage volume per shelf, which adds up significantly across five shelves.
Buy a unit that fits your wall and leave room in front for comfortable access. That access aisle is as important as the shelf depth itself.
