Why Shelving Size Is More Important Than You Think
Choosing the wrong shelving size is one of the most common — and costly — mistakes when setting up a garage or warehouse. Too small, and you're constantly reorganising. Too large, and you waste floor space and create safety hazards. This guide walks you through exactly how to size your shelving correctly, whether you're fitting out a home garage in Sydney or a distribution centre in Melbourne.
Step 1: Measure Your Space First
Before looking at any product specs, grab a tape measure and record:
- Floor-to-ceiling height — subtract 200–300mm for clearance above the top shelf
- Available wall length — how many bays can you fit side by side?
- Aisle width requirements — allow at least 900mm for foot traffic, 2.5–3m for forklift access
- Door and window clearances — mark these on a rough floor plan
Pro tip: Sketch your floor plan to scale on graph paper or use a free tool like RoomSketcher. It takes 10 minutes and saves hours of rearranging later.
Step 2: Know the Key Dimensions
Shelving units are defined by three measurements: height × width × depth. Here's what each means in practice:
Height
Standard heavy-duty shelving ranges from 1.5m to 3m tall. For most Australian garages with 2.4m ceilings, a 1.8m–2.1m unit is the sweet spot — tall enough to maximise vertical storage, short enough to load safely without a ladder. For warehouses with 4m+ clearance, taller bays make sense with appropriate access equipment.
Width (Bay Width)
Common bay widths are 900mm, 1200mm, and 1500mm. Wider bays hold more per level but require heavier-gauge uprights to maintain load ratings. For most applications, 1200mm is the most versatile width — it fits standard pallets and most bulk storage items.
Depth
Shelf depth determines what you can store front-to-back. Common depths:
- 300–400mm: Small parts, tools, retail stock
- 450–600mm: Boxes, automotive parts, general warehouse goods
- 600–900mm: Pallets, large machinery components, bulk storage
Match depth to your largest item — items overhanging the shelf edge are a safety risk and reduce effective capacity.
Step 3: Match Shelving to Your Use Case
Home Garage
Most Australian home garages are 5.5m × 5.5m to 6m × 6m. A practical setup: two or three bays of 1800mm (H) × 1200mm (W) × 600mm (D) shelving along the back wall, leaving the centre clear for vehicles or a workbench. Our Heavy Duty Storage Shelving is a popular choice for this layout.
Trade Workshop
Workshops need a mix of depths — shallower shelves for small parts and tools near the workbench, deeper shelves for bulk materials and equipment. Consider a 4-tier configuration to maximise vertical space without sacrificing accessibility.
Small Warehouse (Under 500m²)
Plan your layout around a central aisle with shelving bays running perpendicular. Aim for bays no deeper than 600mm on each side of a 1.2m aisle — this gives you 2.4m of accessible storage width per aisle. Our Heavy Duty 4-Tier Storage Rack is engineered for exactly this kind of high-density layout.
Large Warehouse / Distribution Centre
At scale, consider a professional warehouse layout plan. Key principles: maximise vertical storage, minimise aisle count, and ensure forklift turning radii are accounted for. Shelving heights of 2.4m–3m with 2500kg+ unit capacity are typical.
Step 4: Plan for Growth
One of the most overlooked aspects of shelving selection is future-proofing. Ask yourself:
- Will my inventory grow in the next 2–3 years?
- Will I need to store larger or heavier items?
- Could I add extra bays or shelf levels to existing units?
Choosing a modular shelving system means you can add bays and levels as your business grows — without replacing your entire setup. All Hubrack shelving is designed to be modular and expandable.
