The lever arch files have lived on the floor beside the printer since the last audit. The bookcase in the corner has a shelf that dips in the middle, and someone has balanced a box of copy paper on top. Choosing office bookcases well means matching the size, the shelf load and the wall fixing to what will actually sit on the shelves.
This guide covers sizes, shelf load ratings, melamine against steel, open shelves against cupboards, archive shelving and anchoring, with examples from our bookcases and shelving range.
Office bookcases: heights, widths and depths
A 900mm width is common, so the real choices are height and depth. Low units of 900mm or 1200mm sit under a window or beside a desk, and the top doubles as a surface. Tall units of 1800mm to 2100mm hold far more but need a clear wall and a fixing point.
Depth decides what fits. An A4 lever arch file is roughly 285mm deep standing on a shelf and about 320mm tall. A 315mm deep shelf holds files and books with a little to spare. Archive boxes, equipment cartons and bulk stationery want 400mm to 600mm.
Adjustable shelves let the spacing follow the contents. The Rapid Worker Bookcase Tall ($312) is 900mm wide, 315mm deep and 1800mm high, with 4 adjustable shelves 25mm thick. It is made from E1 Enviroboard melamine with Beech, Oak or White shelves, and extra shelves are available. The same bookcase comes in 900mm and 1200mm heights, so low and tall units can match across a room.
Shelf loads: what a UDL rating tells you
Shelf capacity is usually quoted as a uniformly distributed load, or UDL. It assumes the weight is spread evenly along the shelf. A row of files does that; one heavy box in the middle of a long shelf does not.
Paper is heavier than it looks, so read the rating before filling a shelf. The Steelco Open Bookcase 2000H (from $452) states 40kg UDL per shelf. Where a product page gives no rating, as on the Rapid Worker page, keep the heaviest loads for a unit that states one.
Melamine or steel shelving?
Melamine bookcases suit areas where the shelves are on show. Timber-look and white finishes match the desks, and thick boards such as the Rapid Worker's 25mm shelves suit everyday binders. They usually cost less, and arrive flat-packed for assembly on site.
Steel bookcases suit file rooms, busy shared areas and heavier loads. The Steelco is powder-coated steel with flush side panels, in White Satin, Silver Grey or Graphite Ripple. It comes 900mm or 1200mm wide, 2000mm high and 400mm deep, with 4 adjustable shelves, and the 1200mm width is White Satin only.
The steel unit arrives pre-assembled and carries a 10-year product warranty, against 5 years on the Rapid Worker. The trade-off is weight: the 900mm Steelco weighs 37.9kg and the 1200mm version 46kg. Deliveries go to the ground-floor entrance, so plan two people for the carry.
Open shelves or cupboards with doors
Open shelving is quick to scan and suits reference material used every day, but it shows every untidy row. Doors hide clutter and keep dust off, and a lock protects confidential files and stationery.
The Steelco 4 Shelf Storage Cabinets (from $517) share the 2000mm height of the open bookcase, at 914mm wide and 463mm deep. Reinforced doors close on a three-point locking mechanism with a barrel exchange lock, and they open to 180 degrees. The 4 shelves adjust in 32mm increments and are rated to 40kg UDL. More styles are in our office cupboards range.
A mixed wall often works best: lockable cupboards for private files, with open bookcases in the same colour for binders in daily use. Our guide to furnishing a manager's office around an executive desk shows how storage fits with the desk and visitor chairs.
Archive and storeroom shelving
Old records need capacity, not looks. Australian businesses keep years of records, and the close of each financial year on 30 June sends another round of archive boxes to the storeroom.
The T-span Shelving - Starter Bay (from $275) is 2100mm high, in widths from 910mm to 2160mm and depths of 450mm or 600mm. Heavy-duty T-section uprights carry four shelf levels, which adjust in 50mm steps against built-in position indicators. Each level holds up to 200kg UDL, and the warranty is 10 years. Add-on bays join on as the archive grows.
Where floor space is tight, a mobile compactus holds more in the same footprint. The Compactus 4 Bay Mobile Shelving Unit (from $4,812) runs on a low-profile track 2500mm long, with bays 2175mm high and 900mm or 1200mm wide. Shelves adjust in 25mm increments and carry 75kg UDL each. The unit is fully lockable, has an anti-tilt system and sits on a level floor without being fixed down.
The trade-offs: the 900mm version weighs 270kg, the lead time is 4 to 5 weeks, and it calls for specialised installation rather than self-assembly.

Anchoring tall units in Australian offices and homes
Since 4 May 2025, the Consumer Goods (Toppling Furniture) Information Standard 2024 has been mandatory in Australia. Made under the Australian Consumer Law on the ACCC's recommendation, it covers bookcases 686mm or taller that are consumer goods, meaning goods of a kind likely to be used at home. Suppliers must fix a permanent warning label to them and give tip-over and anchoring warnings online, in stores and in the instructions.
Several of our storage pages carry this notice, including the Rapid Worker, T-span and Steelco cabinet. They state that the item is designed for commercial office use, but must be anchored to the wall if used at home.
In an office, work health and safety laws require a business to eliminate or minimise risks so far as is reasonably practicable, and a tall unit that could tip is one of those risks. A few habits keep tall units stable:
- Fix tall units into studs or masonry with fixings that suit the wall, not into plasterboard alone.
- Load from the bottom up, with the heaviest files on the lowest shelves.
- Never use shelves as a step; keep a step stool nearby for the top shelf.
- Re-check the fixings after any office move or rearrangement.
Office bookcases — frequently asked questions
How deep should an office bookcase be?
For books and lever arch files, 315mm deep is enough. Choose 400mm to 450mm for archive boxes and larger items, and 600mm for storeroom stock.
How much weight can a bookcase shelf hold?
It depends on the unit, so check the stated UDL on the product page. In our range, the Steelco bookcase and cupboard are rated at 40kg per shelf, the compactus at 75kg and T-span shelving at up to 200kg per level.
Do office bookcases need to be anchored to the wall?
Tall bookcases should be anchored wherever they could tip, and several of our product pages say units used at home must be anchored. In an office, anchoring is the simplest way to manage the tip-over risk of tall units. Use fixings that suit the wall type.
Is steel or melamine shelving better for an office?
Steel is better for heavy, constant loads, and the steel units here state their shelf loads. Melamine is better where the bookcase is on show and should match the desks.
