Typical Depths for Office Cabinets in Australia
Cabinet depth has a bigger impact on your workspace than most people realise. In Australian offices, a few common measurements tend to suit most storage needs.
For general storage, office cupboards and metal cabinets usually range from 450 mm to 600 mm deep. Shallow units around 450–500 mm help keep walkways clear and are ideal along corridors or behind workstations. Deeper cabinets closer to 600 mm are better when you need to store bulky files, archive boxes or large folders without them hanging over the edge of the shelf.
Many popular ranges, such as GO Steel Storage, Premier Storage and Steelco Modular Cabinets, are designed around these standard depths to integrate easily with desks and existing fit‑outs. Matching these depths with your workstations helps create a flush, professional look and avoids awkward gaps or overhangs.
When planning your layout, remember to allow additional space in front of hinged doors for them to open fully. For sliding and tambour units, you won’t need that swing clearance, but you should still consider how far the cabinet projects into the room once installed.
How Depth Affects Storage Capacity and Accessibility
Cabinet depth is a balance between fitting more in and keeping everything easy to reach. Going deeper is not always better.
A deeper cupboard can hold more lever arch files, IT equipment and archive boxes, but items may get pushed to the back and forgotten. This is where adjustable office shelving becomes useful, letting you customise shelf spacing to suit what you actually store. If staff frequently access the same items, a mid‑depth cabinet (around 450–500 mm) often strikes the right balance between capacity and visibility.
Accessibility also depends on door style. Traditional office cupboards with hinged doors need extra floor space for the door swing, which can be tricky in tight print rooms or corridors. In those situations, sliding door cabinets and tambour cupboards maintain the same internal depth while saving valuable circulation space at the front.
Think about who will use the storage, how often, and what they need to grab quickly. Keeping frequently used items on the front half of deeper shelves, and reserving the rear area for rarely accessed files, helps you get the most from the available depth without frustrating staff.
Choosing the Right Depth for Different Types of Storage
Different tasks call for different cabinet depths. Matching the unit to its job will keep your workspace organised and efficient.
For general admin and stationery, medium‑depth stationery cupboards provide enough room for reams of paper, folders and consumables without overwhelming smaller offices. When dealing with shared resources like printing supplies or kitchen back‑up items, a 450–500 mm deep cupboard usually gives staff clear visibility of what’s on hand.
For team filing areas or HR and finance records, look for deeper cupboards within ranges such as Premier Storage or Luxe Storage. These systems are designed to handle heavy loads and large volumes of files while maintaining safe shelf spacing. If you’re building a flexible storage wall, mixing shallow and deep modules from collections like Steelco Modular Cabinets can help you accommodate both bulky archives and everyday items.
Open office shelving works well at shallower depths where quick grab‑and‑go access matters more than maximum capacity. For front‑of‑house or client areas, shallower cabinets from lines such as Luxe Storage can provide a sleek, minimal footprint while still hiding clutter. The key is to map each storage zone to a specific purpose, then choose depths that suit that purpose rather than defaulting to one size everywhere.
Measuring Your Space: Clearance, Layout and Safety
Before ordering any storage, take accurate measurements of your space. A few millimetres can make the difference between a seamless fit and a safety hazard.
Start by measuring wall‑to‑wall distance, skirting boards and any power points or data outlets that might sit behind your cabinets. Then factor in the full depth of the unit plus required circulation space. With hinged office cupboards and stationery cupboards, allow additional clearance for the doors to open without blocking corridors or clashing with neighbouring furniture.
In narrow walkways or shared areas, sliding and tambour options are often safer. Sliding door cabinets and tambour cupboards keep door movement within the cabinet footprint, reducing trip risks and congestion. This is especially important in busy spaces like print rooms, copy bays and shared storage areas where several people may be moving around at once.
Finally, consider weight distribution and fixing. Deeper units loaded with files or equipment should be secured according to the manufacturer’s instructions, particularly in seismic zones or multi‑storey buildings. Quality systems such as GO Steel Storage and Premier Storage are engineered with stability in mind, but correct installation and sensible shelf loading are just as important as choosing the right depth.
Popular Storage Ranges and Depth Options to Compare
Once you understand your space and storage needs, comparing product ranges makes the decision easier. Many Australian collections offer multiple depths within the same family.
If you need hard‑wearing, versatile metal units, explore GO Steel Storage and Premier Storage. These lines include a mix of cupboards, filing cabinets and shelving in the most commonly used depths, so you can keep a consistent look while tailoring capacity to each room. For a more architectural finish, Luxe Storage offers contemporary designs that work well in front‑of‑house and executive areas where aesthetics and slim profiles matter.
Modular systems like Steelco Modular Cabinets make it easy to build storage walls that step in and out in depth, following your layout and avoiding obstructions such as columns or windows. You can combine deeper base units for bulk storage with shallower upper cupboards or open office shelving for display and quick access. Mixing in space‑saving pieces like sliding door cabinets and tambour cupboards gives you more flexibility in high‑traffic zones.
When you compare depth options, look beyond the raw measurement and consider how each unit will be used day‑to‑day. Align your choices with specific functions—files, stationery, IT gear, personal storage—and choose from dedicated categories such as office cupboards, stationery cupboards, and specialised office shelving. This functional approach ensures your cabinet depths support the way your team actually works, keeping your office organised, safe and efficient.
