If your garage is looking more like a rubbish tip than a usable space, you’re definitely not alone. Garages tend to accumulate everything and it can be frustrating and overwhelming to manage. That's where we at Space Sheds come in.
We simply help Aussies find the perfect storage solution for their needs. Thankfully, our stock offers a huge range of garage storage cabinet sizes; from compact units perfect for suburban garages, to massive wall-to-wall setups built for serious DIYers, home businesses, or big families.
The right storage cabinet can turn that chaotic garage space into a tidy, functional area that actually works for you.
This guide breaks down small, large, and extra large garage cabinet options so you can understand what each size really fits and ultimately, how to choose a garage cabinet that makes sense for your space, lifestyle, and gear.
Small & Medium Garage Storage (Under 3,000mm Wide)
When you’ve only got a bit of wall space to play with (or you want to start small) a small garage storage cabinet or medium-width setup (up to about 3 metres) is perfect. Don’t let the size fool you. These units punch well above their weight and suit many common garage organisation needs.
Storage Tubs & Household Clutter
Using standard 600mm wide tubs, most small/medium units can fit:
-
4 shelves plus floor space.
-
4 to 5 tubs per shelf.
-
Approximately 18 to 24 medium storage tubs in total.
This is ideal if you want to get seasonal or long term household items off the floor and in order. For many households, one well organised small/medium cabinet can hold an entire cupboard’s worth of clutter.
Typical uses include:
-
Christmas decorations.
-
Kids’ toys, artwork, and keepsake boxes.
-
Old documents, files, tax paperwork.
-
Seasonal clothing and manchester.
-
Camping or light hobby gear.
Tools & DIY Gear
If you’re a weekend DIY warrior, these cabinets offer more than enough space. Expect capacity for:
-
8 to 10 power tool cases (drills, saws, grinders).
-
6 to 8 plastic parts organisers (for screws, nails, fittings).
-
2 small toolboxes.
-
1 compact compressor or vacuum on the bottom.
-
Spare space for 2 to 3 paint cans or extra cleaning supplies.
This size easily handles a complete home DIY setup without taking over your garage. If you’re working toward better garage organisation, this is a strong, budget-friendly starting point.
Large Garage Storage (3,000mm–4,000mm Wide)
Stepping up to a large garage cabinet gives you noticeably more space for gear, tools, or multi-person household storage. This size is great for families or anyone who wants to combine different storage categories (such as tubs, tools, stock, and bulkier items) into one clean wall unit.
High Capacity Tubs & Boxes
With the same 600mm tubs, a large cabinet usually fits:
-
4 shelves plus floor space.
-
5 to 6 tubs per shelf.
-
Approximately 25 to 30 medium storage tubs in total.
If you want garage storage ideas that genuinely give everything its own designated space, this category is worth looking into. That extra width really adds up, making this size suitable for:
-
Whole house decluttering.
-
A small home business stock section.
-
Separate zones for multiple family members.
-
Overflow pantry or linen storage.
-
Camping and outdoor gear.
Workshop or Tradie Storage
If you’re turning your garage into a more serious workshop, or you’re a tradie who wants to keep tools secure and organised, Large units also work beautifully as a dedicated workshop cabinet. Expect capacity for:
-
10 to 14 power tool cases.
-
8 to 12 small parts organisers.
-
4 to 6 larger crates (for cables, safety gear, accessories).
-
Room for 1 welding machine or pressure washer on the bottom.
-
Shelving space for 15 to 20 assorted bottles and cans (oils, sprays, paints).
Extra Large Garage Storage (Over 4,000mm Wide)
If you’ve got the space (and the stuff), an extra large garage cabinet is the ultimate storage solution. These units stretch four metres or more, giving you significant flexibility, extra depth, and room to separate categories clearly.
For families, hobbyists, or home-business owners, this is the most flexible, versatile and future proof option.
Very High Volume Tubs
Using the same medium tubs, extra large cabinets typically fit:
-
4 shelves plus floor space.
-
7 to 8 tubs per shelf.
-
Approximately 35 to 40 medium storage tubs in total.
That’s a seriously impressive amount of storage. If you like the idea of not just organising your garage but transforming it, this is the gold standard, and ideal for:
-
Small business inventory.
-
Bulk pantry overflow.
-
Bulk purchasing storage.
-
Clearly separated family zones (‘Kids’, ‘Camping’, ‘Christmas’, ‘Tools’ and more).
Home Business or Serious Hobby Setup
For hobbyists or home business operators (think online sellers, craft designers, collectors) these units are extremely reliable and helpful. Basically, If you want maximum flexibility without constantly reshuffling shelves, go extra large. Expect capacity for:
-
15 to 20 labelled crates of stock or supplies.
-
6 to 8 archive boxes.
-
8 to 10 small cartons ready for packing orders.
-
A full shelf for packaging (tapes, mailers, bubble wrap).
-
Bottom space for larger equipment such as printers and bulkier items.
How to Choose the Right Size
When choosing among different garage storage cabinet sizes, consider these quick tips:
-
Measure your wall space and don’t forget to account for the door swing, car clearance, and access to power points.
-
Think in categories, not items (for example, ‘camping gear’ instead of ‘fishing rods’ or ‘business supplies’ rather than ‘printers’).
-
Plan for future storage, not just the current clutter.
-
Match the cabinet to your lifestyle because families, DIY lovers, and home businesses all have very different needs.
If you're stuck, a quick sketch of your storage zones is often the easiest way to figure out how to choose a garage cabinet that won’t feel too small. It helps to visualise the space, identify what you have and consider how to efficiently place your belongings.
